MdePkg, OvmfPkg: fix IoWriteFifo8(), and print debug messages with it

[edk2] [PATCH 0/2] MdePkg, OvmfPkg: fix IoWriteFifo8(), and print debug messages with it

Posted by Laszlo Ersek 6 years, 7 months ago

Repo:   https://github.com/lersek/edk2.git
Branch: debugprint_iofifo

The first patch (for MdePkg) fixes an assembly language operand ordering
oversight in the unrolled / SEV implementations of IoWriteFifoXX().

The second patch makes OvmfPkg use IoWriteFifo8() for printing DEBUG
messages and ASSERT() failures.

Thanks,
Laszlo
