Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

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
config and do a little basic setup.
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.
Add a tag to tell dtoc about this, so it knows which one to use when
generating the devices and uclasses.

Move this out of the common header and include it only where needed. In

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
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

Also if the tables point to other tables (such as console log or a ramoops
