991467da4d arch/x86: Add BERT region support functions
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.

5d6593a43c arm64: Factor out common parts of romstage execution flow
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.)

487f7f24a5 arm64: mmu: Spot check security state for TTB mapping
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.

e819c85760 arm64: Turn architectural register accessors into inline functions
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.

0c5f61a01c arm64: Drop checks for current exception level, hardcode EL3 assumption
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
would probably be cleaner to set the expected exception level in a
Kconfig rather than always probing it at runtime.

94e2ec7253 arch: Retire cache_sync_instructions() from <arch/cache.h> (except arm)
cache_sync_instructions() has been superseded by
arch_program_segment_loaded() and friends for a while. There are no uses
in common code anymore, so let's remove it from <arch/cache.h> for all
architectures.

arm64 still has an implementation and one reference, but they are not
really needed since arch_program_segment_loaded() does the same thing
already. Remove them.

Leave it in arm(32) since there are several references (including in SoC
code) that I don't feel like tracking down and testing right now.

e0058e89ab arm64: Reimplement mmu_disable() in assembly
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.

4702914e34 acpi: device: Walk up the tree to find identifier
Instead of just checking the immediate parent for an device name,
walk up the tree to check if any parent can identify the device.

This allows devices to be nested more than one level deep and
still have them identified in one place by the SOC.

The recursive method calling this function has been changed to
handle a null return from acpi_device_name and abort instead of
continuing and perhaps forming an invalid ACPI path.

99f4683adf Introduce bootblock self-decompression
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.

23d62dd15c lib/bootmem: Add more bootmem tags
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.

ARMv7 and ARMv8 specific changes:
* Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE.

ARMv7 specific changes:
* Add _ttb_subtables as BM_MEM_RAMSTAGE.

294446a137 x86/mpspec: order the I/O APICs by the APIC Id
Linux (4.16) assumes that the PIT interrupt is connected to the pin 0 of the
IOAPIC[0] and panics otherwise.

This might be a Linux bug. The MP Specification 1.4 does seem to mandate
sequential ordering for bus entries, but not for the I/O APICs.

4b032e457f arch/x86: allow idt to be available to link in all stages
Add Kconfig IDT_IN_EVERY_STAGE to optionally specify having
the interrupt handling code available to all stages. In order
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
the interrupt vector entry points can be used to dynamically
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
location.

0f35af8f42 arch/x86: add support for cache-as-ram paging
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.

99f54a60bf include/memory_info.h: Change serial number field from 5 bytes to 4
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.

Testing this on grunt, dmidecode now shows the full serial number:
        Serial Number: 00000000

042a8336f3 arch/riscv: Pass the bootrom-provided FDT to the payload
The RISC-V boot protocol foresees that at every stage boundary (bootrom

a1 contains the physical address of the Flattened Device Tree that the
stage shall use.

As a first step, pass the bootrom-provided FDT to the payload,
unmodified.

91ebbfdc5c arm64: Pass COREBOOT flag to ARM TF, always enable logging
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.

Add a method in the speedstep ssdt generator to notify all available

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.

2d65d20436 arch/x86: Restore forwarding table on resume for non EARLY_EBDA_INIT
In commit c06a3f72 (arch/x86: initialize EBDA in S3 and S0/S5 path),
BDA and EBDA are wiped in the resume path. It results in coreboot
forwarding table address being wiped out since it is stored in the
BDA. This issue was resolved for platforms using EARLY_EBDA_INIT in
commit f46a9a0d (arch/x86: restore forwarding table on resume for
EARLY_EBDA_INIT). However platforms that do not use EARLY_EBDA_INIT
still run into the same issue and hence cbmem does not work on
resume. This change fixes the issue by using the stash/restore of
forwarding table address for all platforms using BDA.

BUG=b:68412690

There are two warnings:
* In LATE_CBMEM_INIT's help text, I've added a multi-line warning, that
  aims to explain the problem.
* In src/mainboard/Kconfig (just below the mainboard selection), there's
  a warning which points the user at LATE_CBMEM_INIT, if such a board is
  selected.

Also update the function that needs to be implemented, as pointed out by

0f2dd1eff9 include/device: Split i2c.h into three
Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.

* `i2c.h`        - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
                   per board, devicetree independent I2C interface
* `i2c_bus.h`    - will become the devicetree compatible interface for
                   native I2C (e.g. non-SMBus) controllers

a102a029c5 arch/x86: Make postcar TempRamExit call generic
Move the FSP-specific call for tearing down cache-as-RAM out of
postcar.c and replace it with an empty weak function.

This patch omits checking if (IS_ENABLED(CONFIG_FSP_CAR)).  The
temp_ram_exit.c file with the real fsp_temp_ram_exit() is only built
when CONFIG_FSP_CAR is true.

ce9c88348c arch/x86/assembly_entry: Align stack for car_stage_entry
At process _start, the stack is expected to be aligned to a
16-byte boundary.  Upon entry to any function the stack frame
must have the end of any arguments also aligned.  In other words
the value of %esp+4 or %rsp+8 is always a multiple of 16 (1).

Align the stack down and change the method for executing
car_stage_entry from jmp to call which should preserve proper
alignment regardless of a 32- or 64-bit build.

Although 4-byte alignment is the minimum requirement for i386,
some AMD platforms use SSE instructions which expect 16-byte.

   See "Initial Stack and Register State" and "The Stack Frame"
   in the supplements.

cd6b22f9a0 arch: Unify basic cache clearing API
Caching is a very architecture-specific thing, but most architectures
have a cache in general. Therefore it can be useful to have a generic
architecture-independent API to perform simple cache management tasks
from common code.

We have already standardized on the dcache_clean/invalidate naming
scheme that originally comes from ARM in libpayload, so let's just do
the same for coreboot. Unlike libpayload, there are other things than
just DMA coherency we may want to achieve with those functions, so
actually implement them for real even on architectures with
cache-snooping DMA like x86. (In the future, we may find applications
like this in libpayload as well and should probably rethink the API
there... maybe move the current functionality to a separate
dma_map/unmap API instead. But that's beyond scope of this patch.)

baa3e70084 arm64: Align cache maintenance code with libpayload and ARM32
coreboot and libpayload currently use completely different code to
perform a full cache flush on ARM64, with even different function names.
The libpayload code is closely inspired by the ARM32 version, so for the
sake of overall consistency let's sync coreboot to that. Also align a
few other cache management details to work the same way as the
corresponding ARM32 parts (such as only flushing but not invalidating
the data cache after loading a new stage, which may have a small
performance benefit).

Also setup ATF builds so that unused functions don't break the build.
They're harmless and they don't filter for these like we do.

a7dd645594 CBMEM: Add config CBMEM_TOP_BACKUP
AGESA and binaryPI boards have no easy way to determine correct
cbmem_top() location early enough when GFXUMA is enabled, so they
will use these functions with EARLY_CBMEM_INIT as well.

At the end of AmdInitPost() the decisions of UMA base and size
have not been written to hardware yet. The decisions are stored
inside AGESA heap object we cannot locate from coreboot proper
until after AmdInitEnv().

Modify code such that weak backup functions are only defined
for LATE_CBMEM_INIT; they are somewhat troublesome to handle.

e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

94d9411415 vboot: Remove CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL Kconfig option
CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to
provide its own main() symbol that can execute code before the generic
verstage code runs. We have now established in other places (e.g. T210
ramstage) a sort of convention that SoCs which need to run code in any
stage before main() should just override stage_entry() instead. This
patch aligns the verstage with that model and gets rid of the extra
Kconfig option. This also removes the need for aliasing between main()
and verstage(). Like other stages the main verstage code is now just in
main() and can be called from stage_entry().

that all stages use the same architecture support code.

f797a1ac6a riscv: Suppress invalid coverity errors
Coverity is detecting 'sp' as a variable which has not been initialized.
This is obviously not correct, so this patch *TRIES* to mark it as false

I'm not positive that this will work because the annotation needs to go
on the line above the error, but this error is inside of a # define.

Does the whole #define count as one line?  Can it go on the line
above the #define in the .h file?  Does it have to precede every line
where the #define is used?  The documentation doesn't make this clear.

Should suppress coverity issues: 1368525 & 1368527
uninit_use: Using uninitialized value sp.

   anymore; it's mcall now.
 - Having SBI_ in the name is slightly wrong, too: these numbers are not
   part of the Supervisor Binary Interface, they are just used to
   forward SBI calls (they could be renumbered arbitrarily without
   breaking an OS that's run under coreboot).

Also remove mcall_dev_{req,resp} and the corresponding mcall numbers,
which are no longer used.

6f3a53b6f6 riscv: get SBI calls to work
SBI calls, as it turned out, were never right.
They did not set the stack correctly on traps.
They were not correctly setting the MIP instead of the SIP
(although this was not really well documented).
On Harvey, we were trying to avoid using them,
and due to a bug in SPIKE, our avoidance worked.
Once SPIKE was fixed, our avoidance broke.

This set of changes is tested and working with Harvey
which, for the first time, is making SBI calls.

It's not pretty and we're going to want to rework
trap_util.S in coming days.

d9307c2e8a riscv: Add support for timer interrupts
RISCV requires that timer interrupts be handled in machine
mode and delegated as necessary. Also you can only reset the
timer interrupt by writing to mtimecmp. Further, you must
write a number > mtime, not just != mtime. This rather clumsy
situation requires that we write some value into the future
into mtimecmp lest we never be able to leave machine mode as
the interrupt either is not cleared or instantly reoccurs.

This current code is tested and works for harvey (Plan 9)
timer interrupts.

a01695bf9a Revert "arch/x86/smbios: Correct manufacturer ID"
This reverts commit c86da67436.

Alas, I have to disagree with this in every single line. The comment
added to the top of the file only applies to a single function therein
which sits over a hundred lines below. That's not much helpful. More-
over, the link in the comment is already down ofc.

The comment is also irritating as it doesn't state in which way (enco-
ding!) it applies to the code, which presumably led to the wrong in-
terpretation of the IDs.

At last, if anything should have changed it is the strings, the IDs
are resolved to. `smbios_fill_dimm_manufacturer_from_id()` has to
resolve the IDs it gets actually fed and not a random selection from
any spec.

Since I digged into it, here's why the numbers are correct: The func-
tion started with the SPD encoding of DDR3 in mind. There, the lower
byte is the number of a "bank" of IDs with an odd-parity in the upper
most bit. The upper byte is the ID within the bank. The "correction"
was to clear the parity bit for naught. The function was later exten-
ded with IDs in the DDR2-SPD encoding (which is actually 64-bit not
16). There, a byte, starting from the lowest, is either an ID below
127 plus odd-parity, or 127 which means look in the next byte/bank.
Unused bytes seem to be filled with 0xff, I guess from the 0xff2c.

50e76709ed arm64: arm_tf: Do not build raw bl31.bin binary
coreboot's build system picks up the BL31 image as an ELF from the ARM
Trusted Firmware submodule and inserts it into CBFS. However, the
generic 'bl31' build target we run in the ARM Trusted Firmware build
system also generates a raw bl31.bin binary file.

We don't need that binary, and with the recently added support for
multiple non-contiguous program segments in BL31 it can grow close to
4GB in size (by having one section mapped near the start and one near
the end of the address space). To avoid clogging up people's hard drives
with 4GB of zeroes, let's only build the target we actually need.

571c230252 riscv: Add a bandaid for the new toolchain
After I did a new toolchain build, I found the
the mhartid register value is wrong for Spike.
The docs seem to agree with Spike, not the
code the toolchain produces?

Until such time as the bitstreams and toolchain can find
a way to agree, just hardcode it. We've been playing this game
for two years now so this is hardly a new approach.

This is intentionally ugly because we really need the
toolchains and emulators and bitstreams to sync up,
and that's not happening yet. Lowrisc
allegedly implements the v1.9 spec but it's PTEs are clearly
1.7. Once it all settles down we can just use constants
supplied by the toolchain.

I hope the syncup will have happened by the workshop in November.

This gets spike running again.

5965cba3dc RISCV: Clean up the common architectural code
This version of coreboot successfully starts a Harvey (Plan 9) kernel as a payload,
entering main() with no supporting assembly code for startup. The Harvey port
is not complete so it just panics but ... it gets started.

We provide a standard payload function that takes a pointer argument
and makes the jump from machine to supervisor mode;
the days of kernels running in machine mode are over.

We do some small tweaks to the virtual memory code. We temporarily
disable two functions that won't work on some targets as register
numbers changed between 1.7 and 1.9. Once lowrisc catches up
we'll reenable them.

We add the PAGETABLES to the memlayout.ld and use _pagetables in the virtual
memory setup code.

We now use the _stack and _estack from memlayout so we know where things are.
As time goes on maybe we can kill all the magic numbers.

e2e40cc17e riscv: Clean up {qemu,spike}_util
spike_util.h:
 - (LOG_)REGBYTES and STORE are already defined in
   arch/riscv/include/bits.h.
 - TOHOST_CMD, FROMHOST_* are helper macros for the deprecated
   Host-Target Interface (HTIF).

qemu_util.c:
 - mcall_query_memory now uses mprv_write_ulong instead of first
   translating the address and then accessing it normally. Thus,
   translate_address isn't used anymore.
 - Several functions used the deprecated HTIF CSRs mtohost/mfromhost.
   They have mostly been replaced by stub implementations.
 - htif_interrupt and testPrint were unused and have been deleted.

spike_util.c:
 - translate_address and testPrint were unused and have been deleted.

After this commit, spike_util.c and qemu_util.c are exactly the same and
can be moved to a common location.

7ae73fc3a0 arm64: Use 'payload' format for ATF instead of 'stage'
Switch the BL31 (ARM Trusted Firmware) format to payload so that it can
have multiple independent segments. This also requires disabling the region
check since SRAM is currently faulted by that check.

This has been tested with Rockchip's pending change:

with the patch mentioned on the bug at #13.

correct though:

1e9a914207 arch/x86,lib: make cbmem console work in postcar stage
Implement postcar stage cbmem console support. The postcar stage
is more like ramstage in that RAM is already up. Therefore, in
order to make the cbmem console reinit flow work one needs the cbmem
init hook infrastructure in place and the cbmem recovery called.
This call is added to x86/postcar.c to achieve that. Additionally,
one needs to provide postcar stage cbmem init hook callbacks for
the cbmem console library to use. A few other places need to
become postcar stage aware so that the code paths are taken.
Lastly, since postcar is backed by ram indicate that to the
cbmem backing store.

In the current implementation of postcar_frame_add_mtrr,
if provided size is bigger than the base address alignment,
the alignment is considered as size and covered by the MTRRs
ignoring the specified size.
In this case the callee has to make sure that the provided
size should be smaller or equal to the base address alignment
boundary.

To simplify this, utilize additonal MTRRs to cover the entire
size specified. We reuse the code from cpu/x86/mtrr/mtrr.c.

f643d661e1 arch/riscv: Add functions to read/write memory on behalf of supervisor/user mode
Normally machine-mode code operates completely within physical address
space. When emulating less privileged memory accesses (e.g. when the
hardware doesn't support unaligned read/write), it is useful to access
memory through the MMU (and with virtual addresses); this patch
implements this functionality using the MPRV bit.

The "fence" instruction represents a full memory fence, as opposed to
variants such as "fence r, rw" which represent a partial fence. An
operating system might want to use precisely the right fence, but
coreboot doesn't need this level of performance at the cost of
simplicity.
