6588652ef5 mb/emulation/qemu-armv7: Fix board
Fix multiple issues allowing to boot until "Payload not loaded":

* The FMAP_CACHE was placed in memory mapped flash
  - Place the FMAP_CACHE in DRAM.
* The FMAP_CACHE was overlapping the BOOTBLOCK, which has a default size
  of 128KiB.
  - Increase the bootblock size in memlayout to 128KiB to match the FMAP.
* The heap in bootblock wasn't usable.
  - Add a linking check in armv7 common bootblock to relocate itself to
    the linked address.
* A FIT payload couldn't be compiled in as the POSTRAM_CBFS_CACHE was
  missing.
  - Add the POSTRAM_CBFS_CACHE to memlayout.
* The coreboot log is spammed with missing timestamp table error messages
  - Add TIMESTAMP table to memlayout.

Tested on QEMU armv7 vexpress.

e69b1af925 armv7: mmu: Use 'tlbimva' to invalidate TLB entries
The tlbimvaa operation (invalidate unified TLB by MVA, all address
space identifiers) is only available on armv7 processors that support
Multiprocessing Extensions. When used on processors that do not support
the extensions it causes an "undefined instruction" exception.

This patch changes the MMU table entry filling code to use the tlbimva
(invalidate unified TLB entry by MVA and address space identifier)
operation for invalidating TLB entries, which is supported on all armv7
processors.

As address space identifiers are not used in TLB entries in coreboot
(all entries are set as global), these two operations can safely be
used interchangeably. The ASID value supplied to the operation is not
checked for global TLB entries.

More information as well as the data formats for the tlbimvaa and
tlbimva operations are detailed in the "ARM Architecture Reference
Manual ARMv7-A" edition, issue "C.c" page B4-1747.

46514c2b87 treewide: Add Kconfig variable MEMLAYOUT_LD_FILE
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows
SoC/mainboard to provide a linker file for the platform. x86 already
provides a default memlayout.ld under src/arch/x86. With this new
Kconfig variable, it is possible for the SoC/mainboard code for x86 to
provide a custom linker file as well.

Makefile.inc is updated for all architectures to use this new Kconfig
variable instead of assuming memlayout.ld files under a certain
path. All non-x86 boards used memlayout.ld under mainboard
directory. However, a lot of these boards were simply including the
memlayout from SoC. So, this change also updates these mainboards and
SoCs to define the Kconfig as required.

BUG=b:155322763
TEST=Verified that abuild with --timeless option results in the same
coreboot.rom image for all boards.

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 placed in a followup commit.

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.

155c8023dd AUTHORS: Move src/arch/arm copyrights into AUTHORS file
As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file.  This will happen a bit at a time, as we'll be unifying
license headers at the same time.

Additional changes in this patch:
- Make sure files say that they're part of the coreboot project
- Move descriptions below the license header
- Fix some spacing

0c4ed4bd7e arch, include, soc: Use common stdint.h
There are only minimal differences between the architecture specific
stdint.h implementations, so let's tidy them up and merge them together
into a single file. In particular,

- Use 'unsigned long' for uintptr_t. This was already the case for x86
  and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64
  used 'unsigned long long'. This change allows using a single integer
  type for uintptr_t across all architectures, and brings it into
  consistency with the rest of the code base, which generally uses
  'unsigned long' for memory addresses anyway. This change required
  fixing several assumptions about integer types in the arm code.
- Use _Bool as the boolean type. This is a specialized boolean type that
  was introduced in C99, and is preferrable over hacking booleans
  using integers. romcc sadly does not support _Bool, so for that we
  stick with the old uint8_t.
- Drop the least and fast integer types. They aren't used
  anywhere in the code base and are an unnecessary maintenance burden.
  Using the standard fixed width types is essentially always better anyway.
- Drop the UINT64_C() macro. It also isn't used anywhere and doesn't
  provide anything that a (uint64_t) cast doesn't.
- Implement the rest of the MIN and MAX numerical limits.
- Use static assertions to check that the integer widths are correct.

This patch cleans up remaining uses of raw boolean Kconfig values I
could find by wrapping them with CONFIG(). The remaining naked config
value warnings in the code should all be false positives now (although
the process was semi-manual and involved some eyeballing so I may have
missed a few).

7e0dea6317 symbols.h: Add macro to define memlayout region symbols
When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.

This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).

Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

83bd46e5e5 selfboot: remove bounce buffers
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.

Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.

Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.
