eb2ebbcf56 x86: apl: Use memory-mapped access for VBT
Use the new binman memory-mapping function to access the VBT, to simplify
the code.

0990c894cc x86: fsp: Support a warning message when DRAM init is slow
With DDR4, Intel SOCs take quite a long time to init their memory. During
this time, if the user is watching, it looks like SPL has hung. Add a
message in this case.

This works by adding a return code to fspm_update_config() that indicates
whether MRC data was found and a new property to the device tree.

Also add one more debug message while starting.

ef5f5f6ca6 x86: Avoid #ifdef with CONFIG_HAVE_ACPI_RESUME
At present this enables a few arch-specific members of the global_data
struct which are otherwise not part of the struct. As a result we have to
use #ifdef in various places.

The cost of always having these in the struct is small. Adjust things so
that we can use compile-time code instead of #ifdefs.

3dada5a1a8 x86: fsp: Reinit the FPU after FSP meminit
The APL FSP appears to leave the FPU in a bad state in that it has
registers in use. This causes an error when the next FPU operation is
performed.

Work around this by re-resetting the FPU after calling FSP-M. This allows
the freetype console to work correctly.

0621b5e1ee cbfs: Don't require the CBFS size with cbfs_init_mem()
The size is not actually used since it is present in the header. Drop this
parameter. Also tidy up error handling while we are here.

c793dbdb90 x86: fsp: Allow skipping init code when chain loading
It is useful to be able to boot the same x86 image on a device with or
without a first-stage bootloader. For example, with chromebook_coral, it
is helpful for testing to be able to boot the same U-Boot (complete with
FSP) on bare metal and from coreboot. It allows checking of things like
CPU speed, comparing registers, ACPI tables and the like.

When U-Boot is not the first-stage bootloader much of this code is not
needed and can break booting. Add checks for this to the FSP code.

Rather than checking for the amount of available SDRAM, just use 1GB in
this situation, which should be safe. Using 2GB may run into a memory
hole on some SoCs.

3cabcf966d x86: Move acpi_s3.h to include/acpi/
This header relates to ACPI and we are about to add some more ACPI
headers. Move this one into a new directory so they are together.

The header inclusion in pci_rom.c is not specific to x86 anymore, so drop
the #ifdef CONFIG_X86.

cf87d3b503 x86: fsp: Add FSP2 base support
Add support for some important configuration options and FSP memory init.
The memory init uses swizzle tables from the device tree.

Support for the FSP_S binary is also included.

Bootstage timing is used for both FSP_M and FSP_S and memory-mapped SPI
reads.
