4fb2536e5b x86: Allow listing MTRRs in SPL
Move MTRR-listing code into a common file so it can be used from SPL.
Update the 'mtrr' command to call it.

Use this in SPL just before adjusting the MTRRs, so we can see the state
set up by the board. Only show it when debug is enabled.

2f5210b703 x86: coreboot: Show unimplemented sysinfo tags
Sometimes coreboot adds new tags that U-Boot does not know about. These
are silently ignored, but it is useful to at least know what we are
missing.

Add a way to collect this information. For Brya it shows:

   Unimpl. 38 41 37 34 42 40

These are:

   LB_TAG_PLATFORM_BLOB_VERSION
   LB_TAG_ACPI_CNVS
   LB_TAG_FMAP
   LB_TAG_VBOOT_WORKBUF
   LB_TAG_TYPE_C_INFO
   LB_TAG_BOARD_CONFIG

368fd56466 x86: coreboot: Collect the address of the ACPI tables
At present any ACPI tables created by prior-stage firmware are ignored.
It is useful to be able to view these in U-Boot.

Pick this up from the sysinfo tables and display it with the cbsysinfo
command. This allows the 'acpi list' command to work when booting from
coreboot.

Adjust the global_data condition so that acpi_start is available even if
table-generation is disabled.

cf9f38064d x86: mtrr: Fix parsing of "mtrr list" command
The command 'mtrr' does not recognize the 'list' subcommand any more
since the code restructuring in commit b2a76b3fe7 ("x86: mtrr:
Restructure so command execution is in one place").

The if-else parsing the command arguments does not take 'list' into
account: the if-branch is intended for no subcommands, the else-branch
is intended for the non-list subcommands (which all expect additional
arguments). Calling the 'mtrr list' subcommand leads to a "return
CMD_RET_USAGE" in the else-branch.

Fix this by changing the else-branch to explicitly checking for
if (cmd != 'l').

We should not use typedefs in U-Boot. They cannot be used as forward

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.
