r1127 - coreboot-v3/arch/x86

Author: mjones

New Revision: 1127

Modified:
   coreboot-v3/arch/x86/stage1.c
Log:
Coreboot uses the compiler option -mregparm=3 which causes variables to 
be passed in registers. This is good for size and speed but not good when
we call a C function from asm. Force stage1_phase1 to use stdcall and get
variables off the stack.

Note that I didn't change stage1_phase3 because it doesn't use any 
variables.
