CBFS used to have a special region for the x86 bootblock, which also
contained a pointer to a CBFS master header, which describes the
layout of the CBFS.
Since we adopted other architectures, we got rid of the bootblock region
as a separate entity and add the x86 bootblock as a CBFS file now.
The master header still exists for compatibility with old cbfstool
versions, but it's neatly wrapped in either the bootblock file or in a
file carefully crafted at the right location (on all other architectures).
All the layout information we need is now available from FMAP, a core
part of a contemporary coreboot image, even on x86, so we can just use
the generic master header locator in src/lib/cbfs.c and get rid of the
special version.
Among the advantages: the x86 header locator reduced the size of the
CBFS by 64 bytes assuming that there's the bootblock region of at least
that size - this breaks assumptions elsewhere (eg. when walking CBFS in
cbfs_boot_locate() because the last file, the bootblock, will exceed the
CBFS region as seen by coreboot (since it's CBFS - 64bytes).

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.

need to increment the program counter by the size of instruction.
Otherwise the same instruction is executed (and emulated) again and again.
While were at it: Also return early in the unlikely case that the
faulting instruction is not 16 or 32 bits long, and be more explicit
about the return values of fetch_*bit_instruction.

Add code for generating the region pointed to in an ACPI Boot Error
Record Table.
The BERT region must be reported as Reserved to the OSPM, so this
code calls out to a system-specific region locator. cbmem is
reported as type 16 and is not usable for the BERT region.
Events reported via BERT are Generic Error Data, and are constructed
as follows (see ACPI and UEFI specs for reference):
* Each event begins with a Generic Error Status Block, which may
contain zero or more Generic Data Entries
* Each Generic Data Entry is identifiable by its Section Type field,
and the data structures associated are also in the UEFI spec.
* The GUIDs are listed in the Section Type field of the CPER
Section Descriptor structure. BERT doesn't use this structure
but simply uses its GUIDs.
* Data structures used in the Generic Data Entry are named as
Error Sections in the UEFI spec.
* Some sections may optionally include a variable number of
additional structures, e.g. an IA32/X64 processor error
can report error information as well as machine contexts.
It is worth noting that the Linux kernel (as of v4.4) does not attempt
to parse IA32/X64 sections, and opts to hexdump them instead.

The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

Since commit 372d0ff1d1 (arch/arm64: mmu: Spot check TTB memory
attributes), we already check the memory attributes that the TTB region
is mapped with to avoid configuration mistakes that cause weird issues
(because the MMU walks the page tables with different memory attributes
than they were written with). Unfortunately, we only checked
cachability, but the security state attribute is just as important for
this (because it is part of the cache tag, meaning that a cache entry
created by accessing the non-secure mapping won't be used when trying to
read the same address through a secure mapping... and since AArch64 page
table walks are cache snooping and we rely on that behavior, this can
lead to the MMU not seeing the new page table entries we just wrote).
This patch adds the check for security state and cleans up that code a
little.

Accesses to architectural registers should be really fast -- they're
just registers, after all. In fact, the arm64 architecture uses them for
some timing-senstive uses like the architectural timer. A read should be:
one instruction, no data dependencies, done.
However, our current coreboot framework wraps each of these accesses
into a separate function. Suddenly you have to spill registers on a
stack, make a function call, move your stack pointer, etc. When running
without MMU this adds a significant enough delay to cause timing
problems when bitbanging a UART on SDM845.
This patch replaces all those existing functions with static inline
definitions in the header so they will get reduced to a single
instruction as they should be. Also use some macros to condense the code
a little since they're all so regular, which should make it easier to
add more in the future. This patch also expands all the data types to
uint64_t since that's what the actual assembly instruction accesses,
even if the register itself only has 32 bits (the others will be ignored
by the processor and set to 0 on read). Arm regularly expands registers
as they add new bit fields to them with newer iterations of the
architecture anyway, so this just prepares us for the inevitable.

When we first created the arm64 port, we weren't quite sure whether
coreboot would always run in EL3 on all platforms. The AArch64 A.R.M.
technically considers this exception level optional, but in practice all
SoCs seem to support it. We have since accumulated a lot of code that
already hardcodes an implicit or explicit assumption of executing in EL3
somewhere, so coreboot wouldn't work on a system that tries to enter it
in EL1/2 right now anyway.
However, some of our low level support libraries (in particular those
for accessing architectural registers) still have provisions for
running at different exception levels built-in, and often use switch
statements over the current exception level to decide which register to
access. This includes an unnecessarily large amount of code for what
should be single-instruction operations and precludes further
optimization via inlining.
This patch removes any remaining code that dynamically depends on the
current exception level and makes the assumption that coreboot executes
at EL3 official. If this ever needs to change for a future platform, it

Disabling the MMU with proper cache behavior is a bit tricky on ARM64:
you can flush the cache first and then disable the MMU (like we have
been doing), but then you run the risk of having new cache lines
allocated in the tiny window between the two, which may or may not
become a problem when those get flushed at a later point (on some
platforms certain memory regions "go away" at certain points in a way
that makes the CPU very unhappy if it ever issues a write cycle to
them again afterwards).
The obvious alternative is to first disable the MMU and then flush the
cache, ensuring that every memory access after the flush already has the
non-cacheable attribute. But we can't just flip the order around in the
C code that we have because then those accesses in the tiny window
in-between will go straight to memory, so loads may yield the wrong
result or stores may get overwritten again by the later cache flush.
In the end, this all shouldn't really be a problem because we can do
both operations purely from registers without doing any explicit memory
accesses in-between. We just have to reimplement the function in
assembly to make sure the compiler doesn't insert any stack accesses at
the wrong points.

Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.
This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.
This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.
NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

This is a simple structure format which indicates what type of

Introduce new bootmem tags to allow more fine grained control over buffer
allocation on various platforms. The new tags are:
BM_MEM_RAMSTAGE : Memory where any kind of boot firmware resides and that
should not be touched by bootmem (by example: stack,
TTB, program, ...).
BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should
not be touched by bootmem.
Starting with this commit all bootmem methods will no longer see memory
that is used by coreboot as usable RAM.
Bootmem changes:
* Introduce a weak function to add platform specific memranges.
* Mark memory allocated by bootmem as BM_TAG_PAYLOAD.
* Assert on failures.
* Add _stack and _program as BM_MEM_RAMSTAGE.

to do this the idt setup is moved to a C module. The vecX
entries are made global so that a table of references to all

initialize the idt. The ramification for ramstage is that
exceptions are initialized later (lib/hardwaremain.c). Not
all stages initialize exceptions when this Kconfig variable
is selected, but bootblock for the C, stages using
assembly_entry.S, and of course ramstage do. Anything left
out just needs a call to exception_init() at the right

Processors, such as glk, need to have paging enabled while
in cache-as-ram mode because the front end is agressive about
fetching lines into the L1I cache. If the line is dirty and in
the L1D then it writes it back to "memory". However, in this case
there is no backing store so the cache-as-ram data that was written
back transforms to all 0xff's when read back in causing corruption.
In order to mitigate the failure add x86 architecture support for
enabling paging while in cache-as-ram mode. A Kconfig variable,
NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve
out for page tables within the cache-as-ram region. Additionally,
the page directory pointer table is also carved out of cache-as-ram.
Both areas are allocated from the persist-across-stages region
of cache-as-ram so all stages utilizing cache-as-ram don't corrupt
the page tables.
The two paging-related areas are loaded by calling
paging_enable_for_car() with the names of cbfs files to load the
initial paging structures from.

dimm_info.serial had a strange contract. The SPD spec defines a 4 byte
serial number. dimm_info.serial required a 4 character ascii string with
a null terminator.
This change makes the serial field so it matches the SPD spec.
smbios.c will then translate the byte array into hex and set it on the
smbios table.
There were only two callers that set the serial number:
* haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so
it already matches the new contract.
* amd_late_init.c: Previously copied the last 4 characters. Requires
decoding the serial number into a byte array.
google/cyan/spd/spd.c: This could be updated to pass the serial number,
but it uses a hard coded spd.bin.

In order to support RISC-V processors with and without the RVC
extension, configure the architecture variant (-march=...) explicitly.
NOTE: Spike does support RVC, but currently doesn't select
ARCH_RISCV_COMPRESSED, because coreboot's trap handler doesn't
support RVC.

The RISC-V Privileged Architecture spec 1.10 requires that the address part of
mtvec is four-byte aligned. The lower two bits encode a "mode" flag and should
be zero for now.
Add the necessary alignment directive before trap_entry.

There are now a few architectural extensions available for ARMv8, some
of which introduce instructions or other features that may be useful.
This allows the user to select an extension implemented on their SoC
which will set the -march option passed into the compiler.

This patch changes the way coreboot builds ARM TF to pass the new
COREBOOT flag introduced with the following pull request:
https://github.com/ARM-software/arm-trusted-firmware/pull/1193
Since the new coreboot support code supports the CBMEM console, we need
to always enable LOG_LEVEL INFO. Supporting platforms will parse the
coreboot table to conditionally enable the serial console only if it was
enabled in coreboot as well.
Also remove explicit cache flushes of some BL31 parameters. Turns out we
never really needed these because we already flush the whole cache when
disabling the MMU, and we were already not doing it for most parameters.

Some x86 platforms don't have a TSC that is invariant w.r.t.
rate to get accurate timestamps. As such a different timestamp
is required. Therefore, allow one to specify non-TSC timestamp
source and not compile in the default x86 TSC code.

The PNOT method never notifies the CPU to update it's _CST methods due
to reliance on inexisting variable (PDCx).
Add a method in the speedstep ssdt generator to notify all available
CPU nodes and hook this up in this file.
The cpu.asl file is moved to cpu/intel/speedstep/acpi since it now
relies on code generated in the speedstep ssdt generator. CPUs not
using the speedstep code never included this PNOT method so this is
a logical place for this code to be.
