At present this information is used to locate and parse the tables but is
not stored. Store it so that we can display it to the user, e.g. with the
'bdinfo' command.
Note that now the GD_FLG_SKIP_LL_INIT flag is set in get_coreboot_info(),
so it is always set when booting from coreboot.

To support detecting booting from coreboot, move the code which locates
the coreboot tables into a common place. Adjust the algorithm slightly to
use a word comparison instead of string, since it is faster.

coreboot makes it possible to add own entries into coreboot's
table at a per mainboard basis. As there might be some custom
ones it makes sense to provide a way to process them.

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.

coreboot table definitions can be used by other x86 builds.

The existing IP checksum function is only accessible to the 'coreboot' cpu.
Drop it in favour of the new code in the network subsystem.

There is no need to explicitly write 'arch-coreboot' when including headers,
as when the arch directory points to coreboot the correct files will be
used.

sysinfo.c only contains the lib_sysinfo data structure which
is used/filled by tables.c. This split was introduced by importing
code from libpayload originally, but to keep the code simple, add
the single line of actual code to tables.c

This change also forces the lib_sysinfo structure to be in the .data
section. Otherwise it ends up in the .bss section. U-boot assumes that it
doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.
