Testing on the unmatched shows the code no longer works completely
correctly; Linux has taken over the handling of misalignment
anyway, because handling it in firmware, with the growing
complexity of the ISA and the awkward way in which it
has to be handled, is more trouble than its worth.
Plus, we don't WANT misalignment handled, magically, in
firmware: the cost of getting it wrong is high (as I've
spent a month learning); the performance is terrible (350x
slowdown; and most toolchains now know to avoid unaligned
load/store on RISC-V anyway.
But, mostly, if alignment problems exist, *we need to know*,
and if they're handled invisibly in firmware, we don't.
The problem with invisible handling was shown a while back
in the Go toolchain: runtime had a small error, such that
many misaligned load/store were happening, and it was
not discovered for some time. Had a trap been directed
to kernel or user on misalignment, the problem would
have been known immediately, not after many months.
(The error, btw, was masking the address with 3,
not 7, to detect misalignment; an easy mistake!).
But, the coreboot code does not work any more any way,
and it's not worth fixing. Remove it.
Tested by booting Linux to runlevel 1; before,
it would hang on an alignment fault, as the
alignment code was failing (somewhere).
This takes the coreboot SBI code much closer to
revival.

Older parts do not have the menvcfg csr.
Provide a Kconfig variable, default y, to enable it.
Check the variable in the payload code, when coreboot SBI
is used, and print out if it is enabled.
The SiFive FU540 and FU740 do not support this register;
set the variable to n for those parts.
Add constants for this new CSR.

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.

PMP (Physical Memory Protection) is a feature of the RISC-V
Privileged Architecture spec, that allows defining region(s) of
the address space to be protected in a variety of ways: ranges
for M mode can be protected against access from lower privilege
levels, and M mode can be locked out of accessig to memory
reserved for lower privilege levels. Limits on Read, Write, and
Execute are allowed. In coreboot, we protect against Write and
Execute of PMP code from lower levels, but allow Reading, so as
to ease data structure access. PMP is not a security boundary,
it is an accident prevention device.
PMP is used here to protect persistent ramstage code that is
used to support SBI, e.g. printk and some data structures. It
also protects the SBI stacks. Note that there is one stack per
hart. There are 512- and 1024-hart SoC's being built today, so
the stack should be kept small.
PMP is not a general purpose protection mechanism and it is easy
to get around it. For example, S mode can stage a DMA that
overwrites all the M mode code. PMP is, rather, a way to avoid
simple accidents. It is understood that PMP depends on proper OS
behavior to implement true SBI security (personal conversation
with a RISC-V architect). Think of PMP as "Protection Minus
Protection".
PMP is also a very limited resource, as defined in the
architecture. This language is instructive: "PMP entries are
described by an 8-bit configuration register and one XLEN-bit
address register. Some PMP settings additionally use the address
register associated with the preceding PMP entry. Up to 16 PMP
entries are supported. If any PMP entries are implemented, then
all PMP CSRs must be implemented, but all PMP CSR fields are
WARL and may be hardwired to zero. PMP CSRs are only accessible
to M-mode."
In other words if you implement PMP even a little, you have to
impelement it all; but you can implement it in part by simply
returning 0 for a pmpcfg. Also, PMP address registers (pmpaddr)
don't have to implement all the bits. On a SiFive FU740, for
example, PMP only implements bits 33:0, i.e. a 34 bit address.
PMPs are just packed with all kinds of special cases. There are
no requirements that you read back what you wrote to the pmpaddr
registers. The earlier PMP code would die if the read did not
match the write, but, since pmpaddr are WARL, that was not
correct. An SoC can just decide it only does 4096-byte
granularity, on TOR PMP types, and that is your problem if you
wanted finer granulatiry. SoC's don't have to implement all the
high order bits either.
And, to reiterate, there is no requirement about which of the pmpcfg
are implemented. Implementing just pmpcfg15 is allowed.
The coreboot SBI code was written before PMP existed. In order
for coreboot SBI code to work, this patch is necessary.
With this change, a simple S-mode payload that calls SBI putchar
works:
1:
li a7, 1
li a0, 48
ecall
j 1b
Without this change, it will not work.
Getting this to build on RV32 required changes to the API,
as it was incorrect. In RV32, PMP entries are 34 bits.
Hence, the setup_pmp needed to accept u64. So,
uinptr_t can not be used, as on 32 bits they are
only 32 bit numbers. The internal API uses uintptr_t,
but the exported API uses u64, so external code
does not have to think about right shifts on base
and size.
Errors are detected: an error in base and size will result
in a BIOS_EMERG print, but not a panic.
Boots not bricks if possible.
There are small changes to the internal API to reduce
stack pressure: there's no need to have two pmpcfg_t
on the stack when one will do.
TEST: Linux now boots partly on the SiFive unmatched. There are
changes in flight on the coreboot SBI that will allow Linux to
boot further, but they are out of scope for this patch.
Currently, clk_ignore_unused is required, this requires a
separate patch.

for having explicitly been refusing to add a macro like "__MUSL__" to
announce its own presence.
Using __always_unused and __maybe_unused for everything may be a good
idea. This is how it works in the Linux kernel, so that would at least
make us match some other standard rather than doing our own thing
(especially since the other compiler.h shorthand macros are also
inspired by Linux).

This patch contains several minor cleanups related to compiler.h:
- Replace __always_unused() (which is a Linux-specific concept that
doesn't make sense without also having __maybe_unused(), and had zero
uses in the codebase) with __unused() which moves here from helpers.h
- Add __underscores__ to the names of all attributes in the compiler
attribute shorthand macros. This is necessary to make them work in
files where the same name was already used for an identifier (e.g.
cbfstool/cbfs.h's `unused` array of file types).
- Remove libpayload's own copy of compiler.h and make it directly pull
in the commonlib/bsd copy.

There are too many "FIT" in firmware land. In order to reduce possible
confusion of CBFS_TYPE_FIT with the Intel Firmware Interface Table, this
patch renames it to CBFS_TYPE_FIT_PAYLOAD (including the cbfstool
argument, so calling scripts will now need to replace `-t fit` with `-t
fit_payload`).

It seems that GCC's LTO doesn't like the way we implement
DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than
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.
BUG=b:155322763
TEST=Verified that abuild with --timeless option results in the same

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.

Previously, CBMEM console detected on-the-fly that CAR
migration had happened and relocated cbmem_console_p
accoringlin with car_sync_var(). However, if the CAR_GLOBAL
pointing to another object inside CAR is a relative offset
instead, we have a more generic solution that can be used
with timestamps code as well.

Required to boot a kernel as OpenSBI's instruction emulation feature
is required on that virtual machine.
Tested on SiFive/unleashed:
The earlycon is working. No console after regular serial driver
should take over, which might be related to kernel config.

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.

Also don't define the default as this results in spurious lines in the

The only difference in the generated config.h is that for most board
ARCH_RISCV_M goes from 1 to 0. This should not matter.

Fixes a logic error that sets MPIE, but didn't use mret to return to the payload.
This left MIE set to an undefined value.
Now all modes are handled the same way:
- Trap vector base address point to the payload
- Disable Interrupt
- Return to payload using mret
TEST=Run an M-mode payload
