We use mmu_ranges to track the list of memory ranges and their types for
MMU initialization. We also keep track of used memory ranges in
usedmem_ranges, to avoid them from being re-allocated in
mmu_alloc_range().
The problem is, the CBMEM range (CB_MEM_TABLE) is added to mmu_ranges,
but is never marked as "used" in usedmem_ranges. This potentially causes
any allocation (for example the framebuffer) to overlap with CBMEM. This
issue is observed when DMA_DEFAULT_SIZE is reduced from 32MB to 1MB [1].
Prior to that change, because there isn't enough space above the
coreboot table (with the 4GB upper limit) to fit the 32MB requested
region, the DMA heap is always allocated *below* the coreboot table. And
because the coreboot table is usually the lowest within CBMEM, the DMA
heap region is allocated *below* the whole CBMEM, which happens the
avoid the issue.
Fix the bug by adding CB_MEM_TABLE ranges to usedmem_ranges. The ranges
in usedmem_ranges don't need to be combined because they are not for MMU
initialization (and there's only one CB_MEM_TABLE range).

Weak symbols don't work as expected when you try to override them from
within the same static library. Static libraries are just archives of
individual objects, and when the linker tries to resolve a symbol
against it it simply uses the implementation from the first object that
has one, weak or not. It does not search through all remaining objects
to see if there's also a strong implementation.
We've had multiple cases in libpayload where builds were incorrectly
using the default implementation rather than an optimized arch-specific
implementation for years due to this issue. To prevent it from
recurring, this patch adds some postprocessing script to the Makefile
that checks for this situation and makes the build fail if it creeps in
again.

On arm64 device libpayload reserves 32MB of space for the DMA allocator.
DMA allocators are usually just used for small bounce buffers or DMA
descriptors for SPI, I2C or USB transfers, nothing that should get
anywhere near the size of megabytes.
Presumably the original number was just made arbitrarily large because
it didn't matter. But more recently we have had security applications
(guarding secrets that get received over SPI/I2C from firmware and must
not be visible to the OS after handoff) that made us want to erase the
entire DMA heap just to be sure no driver left a copy of any secret
lying around there. This means the size is no longer fully harmless
because erasing a larger heap takes more time.
Change the default to 1MB which should still be more than more than
enough for any real applications, but should bring the time required to
erase it back into negligible territory.

Our mechanism to override the default (pure C) memory function
implementations (memset, memcpy, memmove) with architecture-specific
optimized assembly versions doesn't actually work: it turns out that
weak functions don't work as you'd naively expect when you pack them
together with a strong definition from a different object into a static
library. When a linker tries to resolve a symbol from a static library,
it just picks the first one it finds, even if it is weak. It doesn't
evaluate all objects in the library to see if there are other strong
definitions.
To fix this, this patch gets rid of the weak symbols and uses Kconfigs
instead. It adds an optimized memmove() implementation for x86 because
that makes things easier (then all architectures either override all
three functions or none of them). Also remove memcmp() from the
functions that can be overridden for now because nobody ever needed that
anyway.

The existing lanczos_weight() implementation naively follows the purely
mathematical definition for the `x == 0` special case. However, the
point of defining that special case is obviously to prevent division by
zero in the general case formula. Unfortunately we are still doing some
multiplications with `x` before we get to the division step, and our
fpmath library loses precision during multiplication. This can lead to
edge cases where `x` is not zero but `x_times_pi` later ends up being 0,
which causes the division to throw an exception after all. (I guess
we've just been lucky to not see this case in practice for now... it
requires the output pixel coordinate to be extremely close to but not
quite on the next input pixel coordinate, which may be rare in practice
with our scaling algorithms.)
This patch fixes the issue by implementing the special case later and
checking if `x_times_pi` is zero instead. Note that as long as we pass
this check, we can be confident that the division cannot fail even
though fpdiv() also truncates the divisor: this is because `x_times_pi`
was calculated from an fpmul() call with the constant fppi(), which has
34 significant bits. Even if x is the smallest possible non-zero value
after scaling for multiplication, the result `x_times_pi` must still
have 18 significant bits. That means it can be scaled down a further 16
bits for division without becoming zero.
Also add a simple unit test forcing exactly this condition to ensure the
code will not regress.

Disks larger than 2TB (technically disks with more than 2^32 blocks, but
for the common block size of 512 that comes out to 2TB) cannot represent
their full amount of blocks in the SCSI READ_CAPACITY(10) command used
by libpayload's USB mass storage driver. The entire driver isn't written
to support block addresses larger than 32 bits anyway.
The SCSI command has been designed in a clever way so that devices are
supposed to return the maximum value (0xffffffff) if the actual value
doesn't fit. However, our code adds one to the value (because it is
actually the address of the last block, but we want to know the number
of blocks). This makes it overflow back to 0 which is not great.
This patch caps the result before incrementing it so that the overflow
cannot occur, allowing us to at least access the first 2TB of super
large USB sticks.

On recent AMD platforms the VRT bit in the StatusD register is
read-writeable and set every 1024msec when RTC power is good.
This leads to a timeout in RtcWaitToUpdate() waiting for the bit
to be set and the gEfiRealTimeClockArchProtocolGuid won't be installed.
The protocol is critical to boot.
Adjust the code to not clear the VRT bit, as RtcWaitToUpdate() will
return an error, as it assumes the VRT bit is read-only and hardwired
to one as on Intel ICHs. While the timeout could be increased it
would also increase boot time by up to a second.
On platforms where the VRT bit is read-only the introduced code
does the same as before.

Add strlen() and strnlen() to commonlib/bsd by rewriting them from
scratch, and remove the same functions from coreboot and libpayload.
Note that in the existing libpayload implementation, these functions
return 0 for NULL strings. Given that POSIX doesn't require the NULL
check and that other major libc implementations (e.g. glibc [1]) don't
seem to do that, the new functions also don't perform the NULL check.

Official EDK2 repository has VARIABLE_SUPPORT defaulting to EMU in
UefiPayloadPkg, switch it to SMMSTORE if coreboot is built with
SMMSTOREv2.
This removes custom default of EDK2_CUSTOM_BUILD_PARAMS for
EDK2_REPO_MRCHROMEBOX which is unnecessary now.

Without this, when doing a clean build with 'make j$(nproc)`, the build

not exist yet.

This change removes the unnecessary conditional compilation around
CBMEM_ID_CSE_BP_INFO and CBMEM_ID_CSE_INFO handling in
cb_parse_cbmem_entry. These CBMEM IDs are only relevant on platforms
with SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD enabled, and platforms without
this config option won't encounter these IDs when calling
cb_parse_cbmem_entry().
BUG=b:305898363
TEST=Builds and boots successfully:
* google/rex0 with SOC_INTEL_CSE_LITE_SKU
* google/rex64 with SOC_INTEL_CSE_LITE_SYNC_BY_PAYLOAD
