This is a revert of a recent logic change in setup_zimage(). We do
actually need to install this information always. Change it to install
from the Coreboot tables if available, else the normal source.

A recent change to disable cache setup when booting from coreboot
assumed that this has been done by SPL. The result is that for the
coreboot board, the cache is disabled (in start.S) and never
re-enabled.
If the cache was turned off, as it is on boards without SPL, we should
turn it back on. Add this new condition.

With x86 we can execute an option ROM either natively or using the
x86 emulator (if enabled with CONFIG_BIOSEMU). Both of these share
the _X86EMU_env variable, with the native code using it to hold
register state during interrupt processing.
At present, in 32-bit U-Boot, the variable is declared twice, once
in common code and once in code only compiled with CONFIG_BIOSEMU.
With GCC 11 this causes a 'multiple definitions' error on boards
with CONFIG_BIOSEMU.
Drop the emulator definition when CONFIG_BIOSEMU is used.

With TPL we don't need full PCI support and it adds to code size. Instead,
a simple_bus driver is good enough to be able to read and write the PCI

So at present there are two drivers in U-Boot called pci_x86. One is in
UCLASS_PCI, used in SPL and U-Boot proper. The other is in
UCLASS_SIMPLE_BUS and used only in TPL.

With the updated changes to bootargs substitution[1], the zboot command
needs to be updated to get its command line from an environment variable
instead of a memory address. This is because the command-line string must
be updated to convert %U to ${uuid}, etc.
In any case it is more flexible to use a environment variable and it is
best to do this before the release to avoid a subsequent change.
Update the command accordingly.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now

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.
