b75617b035 x86: Update the fsp command for FSP2
The current 'fsp' command only works with FSP1. Update it to handle FSP2
as well. Convert everything to hex which is what U-Boot uses.

8331188615 x86: Rename existing FSP code to fsp1
Since there is now a new version of the FSP and it is incompatible with
the existing version, move the code into an fsp1 directory. This will
allow us to put FSP v2 code into an fsp2 directory.

Add a Kconfig which defines which version is in use.

Some of the code in this new fsp1/ directory is generic across both FSPv1
and FSPv2. Future patches will address this.

FSP (CONFIG_HAVE_FSP) and Slim Bootloader (CONFIG_SYS_SLIMBOOTLOADER)
consume HOB (CONFIG_USE_HOB) data from the each HOB list pointer.
Add a common HOB library in lib/hob.c and include/asm/hob.h.

5b931a5080 x86: lib: fsp: Use EFI_GUID and efi_guid_t
Use existing EFI_GUID and efi_guid_t instead of struct efi_guid.
This is pre-work before making a common HOB library.
- Change 'struct efi_guid' to efi_guit_t
- Remove 'struct efi_guid'
- Define GUIDs with EFI_GUID() macro
- Use guidcmp() instead of compare_guid()
- Remove compare_guid()

590cee8315 x86: Update mtrr functions to allow leaving cache alone
At present the mtrr functions disable the cache before making changes and
enable it again afterwards. This is fine in U-Boot, but does not work if
running in CAR (such as we are in SPL).

Update the functions so that the caller can request that caches be left
alone.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

We only need to compile and link these files when building for full
U-Boot.  Move them to under cmd/x86/ to make sure they aren't linked in
and undiscarded due to u_boot_list_2_cmd_* being included).
