commit c7b67a2bb903bb684ef1fa08d1e73918c7909651 Author: zbao fishbaozi@gmail.com Date: Fri Feb 26 20:48:13 2016 +0800
amdfwtool: Fix some PSP2 issues
1. Change the function which pushed one firmware to the one which pushes the whole group. Use fw_table as a parameter instead of using the global table name. 2. Let PSP2 and PSP1 not dependent on the other. It turns out PSP2 can exist without PSP1. For some APU, the PSP directory has to be put in PSP2 field (ROMSIG 0x14).
