This series of patches proposes adding AArch64 Linux host support for
EmulatorPkg. The main difference from IA32/X64 is that it does not
need to convert calling conventions between EFI environment and the
host. It is enough just directly registering the host side functions to
the EmulatorPkg provided UEFI protocols. I tested this feature on the
latest Ubuntu 20.04 with both CLANG38 and GCC5 toolchains.

The patch 1/4 is a trivial typo fix that are required for the 3/4 patch.
The 2/4 adds AArch64 specific stack switch code for EmulatorPkg/Sec. The
3/4 changes EmulatorPkg/Unix/Host to support AArch64. The 4/4 introduces
EmulatorPkg AArch64 Linux host build support.

Akira Moroo (4):
  EmulatorPkg/Unix/Host: Fix typo
  EmulatorPkg/Sec: Add AArch64 support
  EmulatorPkg/Unix/Host: Add AArch64 support
  EmulatorPkg: Add AArch64 Unix host build support
