2014-09-04MdePkg NASM Thunk16: Work around NASM 2.09.04 - 2.10rc1 bugJordan Justen
Without this change, NASM 2.09.04 will hang with OVMF+CSM on both IA32 and X64. Tested on OVMF+CSM on GCC49 with NASM 2.07, 2.09.04 and 2.11.

2014-09-01MdePkg BaseLib NASM Thunk16: Initialize _16GdtrBase to 0Jordan Justen
Previously we were setting it to the start of the GDT in the UEFI driver's copy of BaseLib. This address is irrelavent, since the C code will initialize it to the cooresponding address after the Thunk16 code has been placed in low memory. Additionally, initializing this was causing a link error for the XCLANG toolchain.

2014-09-01MdePkg BaseLib NASM Thunk16: Use bits 16 for 16-bit codeJordan Justen
By using 'bits 16', we can write code for 16-bit use the actual assembly syntax rather than 'DB' and sometimes writing code with seemingly incorrect operands because we know it will run correctly when the processor is running in 16-bit mode.

2011-08-02MdePkg: Fixed hang/reset in thunk code when building with GCC X64geekboy15a
Reverted changes of data areas from .long back to .space 4. This was done because the size of .long is based off of .int and may vary. Using a fixed size is required because these values are for patching code. Also note that .space will automatically initialize the data to zero. Not initializing all values to zero was causing the hang/reset.
