02541601cb x86: fsp: Don't program MTRR for DRAM for FSP1
There are several outstanding issues as to why this does not apply
to FSP1:

* For FSP1, the system memory and reserved memory used by FSP are
  already programmed in the MTRR by FSP.
* The 'mtrr_top' mistakenly includes TSEG memory range that has the
  same RES_MEM_RESERVED resource type. Its address is programmed
  and reported by FSP to be near the top of 4 GiB space, which is
  not what we want for SDRAM.
* The call to mtrr_add_request() is not guaranteed to have its size
  to be exactly the power of 2. This causes reserved bits of the
  IA32_MTRR_PHYSMASK register to be written which generates #GP.

For FSP2, it seems this is necessary as without this, U-Boot boot
process on Chromebook Coral goes very slowly.

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so

d46c0932a9 x86: fsp: Adjust calculations for MTRR range and DRAM top
At present the top of available DRAM is the same as the top of the range
of the low-memory MTRR.

In fact, U-Boot is allowed to use memory up until the start of the FSP
reserved memory. Use that value for low_end, since it makes more memory
available.

Keep the same calculation as before for mtrr_top, i.e. the top of
reserved memory.

A side-effect of this change is that the E820 tables have a single entry
that extends from the bottom of the memory used by U-Boot to the bottom
of the FSP reserved memory. This includes the bloblist, if ACPI tables
are placed there.

c68a1ae6ab bdinfo: x86: vesa: Update fb_base to the correct value
Set this value in global_data so that it is reported correctly on x86

In fact, U-Boot allocates space for the frame buffer even though it is not
used. Then the FSP picks the address itself (e.g. 0xb0000000). So the
value set by U-Boot (high in memory with everything else that is
relocated), is not actually the correct value.

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.

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.
