<stdio.h> header is used for input/output operations (such as printf,
scanf, fopen, etc.). Although some input/output functions can manipulate
strings, they do not need to directly include <string.h> because they
are declared independently.

TF-A migrates the default choice of linker to GCC in order to enable
LTO. Change BL31_LDFLAGS from `--emit-relocs` to '-Wl,--emit-relocs', so
that GCC is able to pass `--emit-relocs` to the linker.

This change is for upcoming arm-trusted uprev commit.
TF-A refactors the toolchain detection in [1][2]. After that `AR`,
`CC`, `LD` and other toolchain variables have precedence over
`CROSS_COMPILE`.
Since ChromeOS build system also sets those toolchain variables when
building coreboot, it results that TF-A uses CrOS GCC instead of
coreboot SDK. It needs to unset those variables in order to make
`CROSS_COMPILE` effective.
TF-A upstream changes the default linker from BFD to GCC in [3].
Therefore, temporarily overriding LD as $(LD_arm64} to fix the below
build error.
aarch64-elf-gcc: error: unrecognized command-line option '--emit-relocs'
In addition, TF-A wrapped LD with single quotes to solve Windows path
issue[4]. On MT8173 platform, `--fix-cortex-a53-843419` is appended to
$(LD_arm64} for ERRATA_A53_843419. It results in the below build error.
/bin/sh: 1: --fix-cortex-a53-843419: not found
Since `--fix-cortex-a53-843419` is never passed to TF-A, simply extract
the LD command from $(LD_arm64) by $(word 1, $(LD_arm64)).

Currently, arch/arm64 requires coreboot to run on EL3 due
to EL3 register access. This might be an issue when, for example,
one boots into TF-A first and drops into EL2 for coreboot afterwards.
This patch aims at making arch/arm64 more versatile by removing the
current EL3 constraint and allowing arm64 coreboot to run on EL1,
EL2 and EL3.
The strategy here, is to add a Kconfig option (ARM64_CURRENT_EL) which
lets us specify coreboot's EL upon entry. Based on that, we access the
appropriate ELx registers. So, for example, when running coreboot on
EL1, we would not access vbar_el3 or vbar_el2 but instead vbar_el1.
This way, we don't generate faults when accessing higher-EL registers.
Currently only tested on the qemu-aarch64 target. Exceptions were
tested by enabling FATAL_ASSERTS.

This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since
all code is BSD licensed anyway.
It also moves some code from libpayloads stdlib.h to
commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is
useful for a subsequent commit that adds devicetree.c into commonlib.
Also we don't support DMA on arm platforms in coreboot (only libpayload)
therefore `dma_malloc()` has been removed and `dma_coherent()` has been
moved to architecture specific functions. Any architecture that tries to
use `dma_coherent()` now will get a compile time error. In order to not
break current platforms like mb/google/herobrine which make use of the
commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a
stub has been added to arch/arm64/dma.c.

It seems that we have some applications where we need to calculate a GCD
in 64 bits. Now, we could instantiate the algorithm multiple times for
different bit width combinations to be able to use the most efficient
one for each problem... but considering that the function usually only
gets called once per callsite per stage, and that software emulation of
64-bit division on 32-bit systems doesn't take *that* long either, we
would probably usually be paying more time loading the second instance
of the function than we save with faster divisions. So let's just make
things easy and always do it in 64-bit and then nobody has to spend time
thinking on which version to call.

In case printk does not work the current exception handler will print a
simple "!" to notify the developer that coreboot is actually there but
something went wrong.
The "!" can be quite confusing when it actually happens that printk does
not work. Since "!" doesn't really say much (if you don't know the
exception arm64 code) the developer (like me) can easily assume that
something went wrong while configuring clocks or baud rate of UART,
since the output seemingly does not seem to make sense.
This adds a little bit more output to assure the developer that what was
printed was actually intended to be printed. Therefore it prints
"EXCEPT" which assures the developer that this was intended output.
It also adds a comment above so that developer can more easily grep
for this message.
It has intentionally not been written as:
```
const char *msg = "\r\n!EXCPT!";
while (*msg)
__uart_tx_byte(*msg++);
```
because in this case the compiler will generate code that will place
`msg` somewhere in bootblock and the code will try to access this using
a memory address. In rare cases (if you link bootblock at the wrong
address) this memory address can be wrong and coreboot will not print
the message. Using individual calls to `__uart_tx_byte` ensures that the
compiler will generate code which directly puts the character bytes into
the argument register without referencing a variable in bootblock.

Having a separate romstage is only desirable:
- with advanced setups like vboot or normal/fallback
- boot medium is slow at startup (some ARM SOCs)
- bootblock is limited in size (Intel APL 32K)
When this is not the case there is no need for the extra complexity
that romstage brings. Including the romstage sources inside the
bootblock substantially reduces the total code footprint. Often the
resulting code is 10-20k smaller.
This is controlled via a Kconfig option.
TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'

This patch removes the prog_locate() step for stages and rmodules.
Instead, the stage and rmodule loading functions will now perform the
locate step directly together with the actual loading. The long-term
goal of this is to eliminate prog_locate() (and the rdev member in
struct prog that it fills) completely in order to make CBFS verification
code safer and its security guarantees easier to follow. prog_locate()
is the main remaining use case where a raw rdev of CBFS file data
"leaks" out of cbfs.c into other code, and that other code needs to
manually make sure that the contents of the rdev get verified during
loading. By eliminating this step and moving all code that directly
deals with file data into cbfs.c, we can concentrate the code that needs
to worry about file data hashing (and needs access to cbfs_private.h
APIs) into one file, making it easier to keep track of and reason about.
This patch is the first step of this move, later patches will do the
same for SELFs and other program types.

having a normal DECLARE_REGION() in <symbols.h> and then an extra
DECLARE_OPTIONAL_REGION() in the C file using it, you just say
DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead
of the usual DECLARE_REGION()). This basically looks the same way in the
resulting object file but somehow LTO seems to like it better.

This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows
SoC/mainboard to provide a linker file for the platform. x86 already
provides a default memlayout.ld under src/arch/x86. With this new
Kconfig variable, it is possible for the SoC/mainboard code for x86 to
provide a custom linker file as well.
Makefile.inc is updated for all architectures to use this new Kconfig
variable instead of assuming memlayout.ld files under a certain
path. All non-x86 boards used memlayout.ld under mainboard
directory. However, a lot of these boards were simply including the
memlayout from SoC. So, this change also updates these mainboards and
SoCs to define the Kconfig as required.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

Over time our printk() seems to acquire more and more features... which
is nice, but it also makes it a little less robust when something goes
wrong. If the wrong global is trampled by some buffer overflow, it
suddenly doesn't print anymore. It would be nice to have at least some
way to tell that we triggered a real exception in that case.
With this patch, arm64 exceptions will print a '!' straight to the UART
before trying any of the more fancy printk() stuff. It's not much but it
should tell the difference between an exception and a hang and hopefully
help someone dig in the right direction sooner. This violates loglevels
(which is part of the point), but presumably when you have a fatal
exception you shouldn't care about that anymore.

To avoid trampling over interesting exception artifacts on the real
stack, our arm64 systems switch to a separate exception stack when
entering an exception handler. We don't want that to use up too much
SRAM so we just set it to 512 bytes. I mean it just prints a bunch of
registers, how much stack could it need, right?
Quite a bit it turns out. The whole vtxprintf() call stack goes pretty
deep, and aarch64 generally seems to be very generous with stack space.
Just the varargs handling seems to require 128 bytes for some reason,
and the other stuff adds up too. In the end the current implementation
takes 1008 bytes, so bump the exception stack size to 2K to make sure it
fits.

Arm CPUs have always had an odd feature that allows you to mask not only
true interrupts, but also "external aborts" (memory bus errors from
outside the CPU). CPUs usually have all of these masked after reset,
which we quickly learned was a bad idea back when bringing up the first
arm32 systems in coreboot. Masking external aborts means that if any of
your firmware code does an illegal memory access, you will only see it
once the kernel comes up and unmasks the abort (not when it happens).
Therefore, we always unmask everything in early bootblock assembly code.
When arm64 came around, it had very similar masking bits and we did the
same there, thinking the issue resolved. Unfortunately Arm, in their
ceaseless struggle for more complexity, decided that having a single bit
to control this masking behavior is no longer enough: on AArch64, in
addition to the PSTATE.DAIF bits that are analogous to arm32's CPSR,
there are additional bits in SCR_EL3 that can override the PSTATE
setting for some but not all cases (makes perfect sense, I know...).
When aborts are unmasked in PSTATE, but SCR.EA is not set, then
synchronous external aborts will cause an exception while asynchronous
external aborts will not. It turns out we never intialize SCR in
coreboot and on RK3399 it comes up with all zeroes (even the reserved-1
bits, which is super weird). If you get an asynchronous external abort
in coreboot it will silently hide in the CPU until BL31 enables SCR.EA
before it has its own console handlers registered and silently hangs.
This patch resolves the issue by also initializing SCR to a known good
state early in the bootblock. It also cleans up some bit defintions and
slightly reworks the DAIF unmasking... it doesn't actually make that
much sense to unmask anything before our console and exception handlers
are up. The new code will mask everything until the exception handler is
installed and then unmask it, so that if there was a super early
external abort we could still see it. (Of course there are still dozens
of other processor exceptions that could happen which we have no way to
mask.)

All targets now have the _cbmem_top_ptr symbol populated via calling

it with cbmem_top_chipset explicitly at the start of ramstage, so the
Kconfig guarding this behavior can be removed.

populate _cbmem_top_ptr with cbmem_top_chipset which is also used in

This solution is very generic and can in principle be implemented on
all arch/soc. Currently the old infrastructure to pass on information
from romstage to ramstage is left in place and will be removed in a
follow-up commit.
Nvidia Tegra will be handled in a separate patch because it has a
custom ramstage entry.
Instead trying to figure out which files can be removed from stages
and which cbmem_top implementations need with preprocessor, rename all
cbmem_top implementation to cbmem_top_romstage.
Mechanisms set in place to pass on information from rom- to ram-stage
will be replaced in a followup commit.

This patch uprevs the Arm Trusted Firmware submodule to the new upstream
master (commit 42cdeb930).
Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff
parameters across platforms which involved changing a few names around.
This patch syncs coreboot back up with that. They also made header
changes that now allow us to directly include all the headers we need
(in a safer and cleaner way than before), so we can get rid of some
structure definitions that were duplicated. Since the version of entry
point info parameters we have been using has been deprecated in Trusted
Firmware, this patch switches to the new version 2 parameter format.
NOTE: This may or may not stop Cavium from booting with the current
pinned Trusted Firmware blob. Cavium maintainers are still evaluating
whether to fix that later or drop the platform entirely.
Tested on GOOGLE_KEVIN (rk3399).

As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file. This will happen a bit at a time, as we'll be unifying
license headers at the same time.
Additional changes in this patch:
- Make sure files say that they're part of the coreboot project
- Move descriptions below the license header
Note that the file include/arch/acpi.h is a fantastic example of why
moving to the authors file is needed. Excluding the guard statements,
it has 8 lines of copyrights for 3 function declarations.

There are only minimal differences between the architecture specific
stdint.h implementations, so let's tidy them up and merge them together
into a single file. In particular,
- Use 'unsigned long' for uintptr_t. This was already the case for x86
and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64
used 'unsigned long long'. This change allows using a single integer
type for uintptr_t across all architectures, and brings it into
consistency with the rest of the code base, which generally uses
'unsigned long' for memory addresses anyway. This change required
fixing several assumptions about integer types in the arm code.
- Use _Bool as the boolean type. This is a specialized boolean type that
was introduced in C99, and is preferrable over hacking booleans
using integers. romcc sadly does not support _Bool, so for that we
stick with the old uint8_t.
- Drop the least and fast integer types. They aren't used
anywhere in the code base and are an unnecessary maintenance burden.
Using the standard fixed width types is essentially always better anyway.
- Drop the UINT64_C() macro. It also isn't used anywhere and doesn't
provide anything that a (uint64_t) cast doesn't.
- Implement the rest of the MIN and MAX numerical limits.
- Use static assertions to check that the integer widths are correct.

This patch makes some minor refactoring to the way the FIT parser
handles config nodes. A lot of this code was written in the dawn age of
depthcharge when its device tree library wasn't as well-stocked yet, so
some of it can be rewritten nicer with more high-level primitives.
There's no point in storing both the string name and the actual FDT node
of a FIT image node separately, since the latter also contains the
former, so remove that. Also eliminate code for the case of not having
an FDT (which makes no sense), and move some more FDT validity/compat
checking into fit_update_compat() (mostly in anticipation of later
changes).
This patch was adapted from depthcharge's http://crosreview.com/1553456
with a couple of modifications specific to coreboot's custom FIT loading
code.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

The selfboot function was changed at some point to take a parameter
which meant "check the allocated descriptors to see if they target
regions of real memory."
The region check had to be buried deep in the last step of loading since
that is where those descriptors were created and used.
An issue with the use of the parameter was that it was not possible
for compilers to easily divine whether the check code was used,
and it was hence possible for the code, and its dependencies, to be
compiled in even if never used (which caused problems for the
rampayload code).
Now that bounce buffers are gone, we can hoist the check code
to the outermost level. Further, by creating a selfload_check
and selfload function, we can make it easy for compilers
to discard unused code: if selfload_check is never called, all
the code it uses can be discarded too.

This patch adds the new, faster architectural register accessors to
libpayload that were already added to coreboot in CB:27881. It also
hardcodes the assumption that coreboot payloads run at EL2, which has
already been hardcoded in coreboot with CB:27880 (see rationale there).
This means we can drop all the read_current/write_current stuff which
added a lot of unnecessary helpers to check the current exception level.
This patch breaks payloads that used read_current/write_current
accessors, but it seems unlikely that many payloads deal with this stuff
anyway, and it should be a trivial fix (just replace them with the
respective _el2 versions).
Also add accessors for a couple of more registers that are required to
enable debug mode while I'm here.

Bounce buffers used to be used in those cases where the payload
might overlap coreboot.
Bounce buffers are a problem for rampayloads as they need malloc.
They are also an artifact of our x86 past before we had relocatable
ramstage; only x86, out of the 5 architectures we support, needs them;
currently they only seem to matter on the following chipsets:
src/northbridge/amd/amdfam10/Kconfig
src/northbridge/amd/lx/Kconfig
src/northbridge/via/vx900/Kconfig
src/soc/intel/fsp_baytrail/Kconfig
src/soc/intel/fsp_broadwell_de/Kconfig
The first three are obsolete or at least could be changed
to avoid the need to have bounce buffers.
The last two should change to no longer need them.
In any event they can be fixed or pegged to a release which supports
them.
For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the
value needed in 1999 for the 32-bit Linux kernel, the original ramstage)
to 0xe00000 (14 Mib) which will put the non-relocatable x86
ramstage out of the way of any reasonable payload until we can
get rid of it for good.
14 MiB was chosen after some discussion, but it does fit well:
o Fits in the 16 MiB cacheable range coreboot sets up by default
o Most small payloads are well under 14 MiB (even kernels!)
o Most large payloads get loaded at 16 MiB (especially kernels!)
With this change in place coreboot correctly still loads a bzImage payload.
Werner reports that the 0xe00000 setting works on his broadwell systems.
