According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.
How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

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.)

This patch changes all existing instances of clrsetbits_leXX() to the
new endian-independent clrsetbitsXX(), after double-checking that
they're all in SoC-specific code operating on CPU registers and not
actually trying to make an endian conversion.
This patch was created by running
sed -i -e 's/\([cs][le][rt]bits\)_le\([136][624]\)/\1\2/g'
across the codebase and cleaning up formatting a bit.

Current code uses CPUID leaf 0x1, EBX bits 16:23 to determine number for
"core count". However, it turns out this number has little to do with
real number of cores. According to SDM vol 2A, it stays for "maximum
number of addressable IDs for logical processors in this physical
package". This does not seem to take into account fusing of giving
processor.
The new code determines 'core count' by dividing thread-level cpus by
reported logical cores. This seems to be the only way to arrive
to number of cores as it is reported in official CPU datasheet.

Due to the way CAR teardown is handled in FSP 1.0, the results of
car_get_var_ptr() aren't always reliable, which can break things when
running with FMAP cache. It might be possible to fix this but would make
the code rather complicated, so let's just disable the feature on these
platforms and hope they die out soon.
Also allow this option to be used by platforms that don't have space for
the cache and want to save a little more code.

This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.
In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.
Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

To prevent this vboot_prepare() is removed from the vboot_locator

To clarify the change the vboot_prepare() has been renamed to

Add support for x86_64 bootblock on qemu.
Introduce a new approach to long mode support. The previous patch set
generated page tables at runtime and placed them in heap. The new
approach places the page tables in memory mapped ROM.
Introduce a new tool called pgtblgen that creates x86 long mode compatible
page tables and writes those to a file. The file is included into the CBFS
and placed at a predefined offset.
Add assembly code to load the page tables, based on a Kconfig symbol and
enter long in bootblock.
The code can be easily ported to real hardware bootblock.
Tested on qemu q35.

On this platform the ramstage is run on a different core so passing

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.

Currently all stages that need cbmem need an implementation of a
cbmem_top function. On FSP and AGESA platforms this proves to be
painful and a pointer to the top of lower memory if often passed via
lower memory (e.g. EBDA) or via a PCI scratchpad register.
The problem with writing to lower memory is that also need to be
written on S3 as one cannot assume it to be still there. Writing
things on S3 is always a fragile thing to do.
A very generic solution is to pass cbmem_top via the program argument.
It should be possible to implement this solution on every
architecture.
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.

The x86 timers are a bit of a mess. Cases where different stages use
different counters and timestamps use different counters from udelays.
The original intention was to only flip TSC_CONSTANT_RATE Kconfig
to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those
counters do run with a constant rate but we just lack tsc_freq_mhz()
implementation for three platforms.
Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a
slow run of calibrate_tsc_with_pit(). This is easy enough to fix with
followup implementation of tsc_freq_mhz() for the platforms.
Implementations with LAPIC_MONOTONIC_TIMER typically will not have
tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However,
as they don't use TSC for udelay() the slow calibrate_tsc_with_pit()
is avoided.
Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900
claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch
that romstage to use UDELAY_TSC.

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).

Keep track of the active timestamp table location using
a CAR_GLOBAL variable. Done this way, the entire table
can be located outside _car_relocatable_data and we only
switch the pointer to CBMEM and copy the data before
CAR gets torn down.
Fix comments about requirements of timestamp_init() usage.
Remove timestamp_cache from postcar and ramstage, as CBMEM
is available early on.

These platforms return to romstage from FSP only after
already having torn CAR down. A copy of the entire CAR
region is available and discoverable via HOB.
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.

Add a generic SuperIO ACPI generator, dropping the need to include
additional code in DSDT for SuperIO.
It generates a device HID based on the decoded I/O range.
Tested on Supermicro X11SSH-TF using AST2400.
The SSDT contains no errors and all devices are present.
Possible TODOs:
* Add "enter config" and "exit config" bytes
* Generate support methods to enter and exit config mode
* Generate support methods to query, change or disable current
resource settings on specific LDNs

tsc_freq_mhz() had a static table of Intel CPU families and crystal
clock, but it is possible to calculate the crystal clock speed dynamically,
and this is preferred over hardcoded table.
On SKL/KBL/CML CPUID.15h.ecx = nominal core crystal clock = 0 Hz
hence we had to use static table to calculate crystal clock.
Recommendation is to make use of CPUID.16h where crystal clock frequency
was not reported by CPUID.15h to calculate the crystal clock.

This patch renames arm_tf.c and arm_tf.h to bl31.c and bl31.h,

functions related to Trusted Firmware, and it removes the annoying
