The {get,set}_option() functions are not type-safe: they take a pointer
to void, without an associated length/size. Moreover, cmos_get_option()
does not always fully initialise the destination value (it has no means
to know how large it is), which can cause issues if the caller does not
initialise the value beforehand.
The idea behind this patch series is to replace the current type-unsafe
API with a type-safe equivalent, and ultimately decouple the option API
from CMOS. This would allow using different storage mechanisms with the
same option system, maximising flexibility.
Most, if not all users of get_option() have a value to fall back to, in
case the option could not be read. Thus, get_int_option() takes a value
to fall back to, which avoids repeating the same logic on call-sites.
These new functions will be put to use in subsequent commits.

The name of the and_mask parameter was a bit misleading, due to the
function inverting the value. Renaming this into clear and set makes it
more obvious what those parameters will actually do.

We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

There was a bug in the UPDs for STAPM settings that required one UPD
field to be extended from 8 to 32 bits, so this patch is a breaking
change to the binary layout, but since the UPD struct fields for the SMU
SoC power and performance tuning parameters aren't populated by the
coreboot code yet and we added some padding after each logical section
in the UPD, this isn't expected to cause too much trouble; the only
thing that is required is that a very recent build of the FSP binaries
need to be used in combination with the new coreboot code that will
populate the struct fields in follow-up patches.

The uPEP device is required to support S0i3. The device has been written
in ASL to make it easier to read and maintain. The device constraints
are purely informational. We use a dummy constraint like the Intel
platforms to keep both linux and Windows functional.
In order for this device to be used by the linux kernel the
ACPI_FADT_LOW_PWR_IDLE_S0 flag must be set. So including it
unconditionally doesn't cause any problems.
The AMD Modern Standby BIOS Implementation Guide defines two UUIDs,
one for getting the device constraints, and one for handling
notifications. This differs from the Intel specification and the linux
driver implementation. For this reason I haven't implemented any of the
notification callbacks yet.

Use the same stack location during relocation as for the permanent
handler.
When the number of CPUs is too large the stacks during relocation
don't fit inside the default SMRAM segment at 0x30000. Currently the
code would just let the CPU stack base grow downwards outside of the
default SMM segment which would corrupt lower memory if S3 is
implemented.
Also update the comment on smm_module_setup_stub().

If we select scancode set #1 and keep that, it can confuse Linux
with keyboards that don't return to set #2 when asked to load the
defaults. This happens for instance with various integrated Think-
Pad keyboards but was also seen with an external PS/2 one.
The chosen configuration, scancode set #2 without translation, seems
to be the default for many systems. So we can expect other payloads
and kernels to work with it.
