6a622311e4 arch/x86: Add option to disable default mmap_boot implementation
On certain platforms, the boot media is either not memory-mapped, or
not mapped at the top of 4G. This makes the default mmap_boot
implementation unsuitable. Add an option to allow such platforms to
define their own mapping implementation.

8c09377dea timestamp: Remove HAS_PRECBMEM_TIMESTAMP_REGION Kconfig
This patch generalizes the approach previously used for ARM32
TTB_SUBTABLES to "auto-detect" whether a certain region was defined in
memlayout.ld. This allows us to get rid of the explicit Kconfig for the
TIMESTAMP region, reducing configuration redundancy and avoiding
confusion when setting up future boards.

(Removing armv4/bootblock_simple.c because it references this Kconfig
and it is a dead file that I just forgot to remove in CL:12076.)

BRANCH=None
BUG=None
TEST=Booted Oak and confirmed that all pre-RAM timestamps are still
there. Built Nyan and Falco.

3834520ba1 arch/arm64: Use correct SPSR.DAIF mask for BL31 and payload
The PSTATE mask bits for Debug exceptions, external Aborts, Interrupts
and Fast interrupts are usually best left unset: under normal
circumstances none of those exceptions should occur in firmware, and if
they do it's better to get a crash close to the code that caused it
(rather than much later when the kernel first unmasks them). For this
reason arm64_cpu_init unmasks them right after boot. However, the EL2
payload was still running with all mask bits set, which this patch
fixes.

BL31, on the other hand, explicitly wants to be entered with all masks
set (see calling convention in docs/firmware-design.md), which we had
previously not been doing. It doesn't seem to make a difference at the
moment, but since it's explicitly specified we should probably comply.

BRANCH=None
BUG=None
TEST=Booted Oak, confirmed with raw_read_daif() in payload that mask
bits are now cleared.

372d0ff1d1 arch/arm64: mmu: Spot check TTB memory attributes
On ARM64, the memory type for accessing page table descriptors during
address translation is governed by the Translation Control Register
(TCR). When the MMU code accesses the same descriptors to change page
mappings, it uses the standard memory type rules (defined by the page
table descriptor for the page that contains that table, or 'device' if
the MMU is off).

Accessing the same memory with different memory types can lead to all
kinds of fun and hard to debug effects. In particular, if the TCR says
"cacheable" and the page tables say "uncacheable", page table walks will
pull stale entries into the cache and later mmu_config_range() calls
will write directly to memory, bypassing those cache lines. This means
the translations will not get updated even after a TLB flush, and later
cache flushes/evictions may write the stale entries back to memory.

Since page table configuration is currently always done from SoC code,
we can't generally ensure that the TTB is always mapped as cacheable.
We can however save developers of future SoCs a lot of headaches and
time by spot checking the attributes when the MMU gets enabled, as this
patch does.

BRANCH=None
BUG=None
TEST=Booted Oak. Manually tested get_pte() with a few addresses.

6be6c8f282 arch/x86: Implement minimal bootblock for C_ENVIRONMENT_BOTOBLOCK
Some newer x86 systems can boot from non-memory-mapped boot media
(e.g. EMMC). The bootblock may be backed by small amounts of SRAM, or
other memory, similar to how most ARM chipsets work. In such cases, we
may not have enough code space for romstage very early on. This means
that CAR setup and early boot media (e.g. SPI, EMMC) drivers need to
be implemented within the limited amount memory of storage available.
Since the reset vector has to be contained in this early code memory,
the bootblock is the best place to implement loading of other stages.

Implement a bootblock which does the minimal initialization, up to,
and including switch to protected mode. This then transfers control
to platform-specific code. No stack is needed, and control is
transferred via a "jmp" such that no stack operations are involved.

8e442dc09a arch/riscv: Add missing license headers

encoding.h and atomic.h are from the riscv codebase and have their
license.

699af19359 arch/x86/Makefile.inc: Update symbol check macro
This was breaking the build on OS X, but also wasn't working correctly
under linux anymore either. It wouldn't print the illegal symbols
when it failed.

- Split the generation of the offenders file from the actual check for
offending symbols and just send all output to /dev/null.
- Rewrite the check for offending symbols in a way that works with OS X.

Tested by adding a global variable to romstage and verifying the
failure is shown correctly.  Verified that it works correctly with no
illegal variables.

9df9e93914 arch/x86: add missing license headers
These were mostly written as part of the coreboot project, so get
the standard coreboot license header.

memmove.c came from the linux kernel, so also gets the standard
coreboot v2 license header, but gets the added attribution that it
was derived from the linux kernel.  Unlike many coreboot files,
this file may not be re-licensed as GPL V3.

7b22d84d55 drivers/pc80: Add optional spinlock for nvram CBFS access
When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following:
AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030]

Decoding the faulting address:
0x000000fdf9103300
        fdf91x          Hypertransport system management region
              33        SysMgtCmd (System Management Command) = 0x33
              3         Base Command Type = 0x3: STPCLK (Stop Clock request)
               3        SMAF (System Management Action Field) = [3:1] = 0x1
               1        Signal State Bit Map = [0] = 0x1

Therefore, the error appears to be triggered by an upstream C1E request.

This was eventually traced to concurrent access to the SP5100's SPI Flash controller by
multiple APs during startup.  Calls to the nvram read functions get_option and read_option
call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash
controller, thus placing the SP5100 in an invalid state.  This limitation is not documented
in any public AMD errata, and was only discovered through considerable debugging effort.
