Commit 1aa60a95bd broke microcode loading for chipsets that have a
microcode blob with a total_size field set to 0. This appears to be
support for older chipsets, where the size was set to 0 and assumed to
be 2048 bytes. The fix is to change the result of the subtraction to a
signed type, and ensure the following comparison is done without
promoting the signed type to an unsigned one.

All of the build configuration is set to produce big endian image on PPC64.
In addition, the toolchain produced by coreboot-sdk does not include little
endian libraries so it is not possible to build LE image even when that
configuration is changed.
This patch changes byte order definition which is required for proper work
of functions that deal with endianness, like read_{le,be}*() or
{le,be}*toh().
It also revealed bugs related to the endianness on BE targets that are
addressed in the following patches.

In x86_64, the first function parameter is passed in rdi register, and
the 32-bit code after exiting long mode reads the resume vector in
4(%esp), so it's needed to save the resume vector from rdi to 4(%rsp).
Also note that the function attribute "regparm" only works on x86-32
targets according to the GCC manual, so "asmlinkage" doesn't change
the ABI of an x86_64 function.

devices on bus 1 and higher to subscribe to IOMMU services. As per AMD
IOMMU spec v3 section 5.2.2.1 all possible device IDs must be defined,
whether the device ID is actually populated or not. Device entries are
used to report ranges when hot-plug and SR-IOV devices are possible.
