commit 770f7664a013c2db9c753ea902e50a0e20b258b8 Author: zbao fishbaozi@gmail.com Date: Wed Jun 17 18:51:42 2015 -0400
AMD/Hudson Makefile: Fill the ROMSIG with 0xFF instead of 0
Besides the first five DWORDs are used in ROMSIG, the offset 0x40 & 0x41 are used to save SPI settings. They should only be 0xFF for being written.
Other parts in ROMSIG are also changed to 0xFF for potential requirement.
