Bring Up BIOS

1. Modify GPIO that depends on platform design
2. Modify FDLA (Firmware Device Linear Address)
3. Change VBIOS
4. Change SPI ROM size
5. Disable KSC

===========================================================================

做一個Bring-up BIOS主要的工作如下:
1. 依照platform的layout去修改GPIO
2. 修改FDLA (Firmware Device Linear Address)
3. 換掉VBIOS
4. 依照platform的設計改變SPI ROM大小
5. 移除KSC

    以上兩項可以再說明一下嘛? 找不到相關的文件呢?

  2. Modify FDLA就是要指定BIOS ROM的大小,例如1mb的BIOS ROM就是用0x100000000 - 0x100000 = 0xFFF00000當作FDLA的起始位置。
    Disable KSC就是把公板上的KSC相關的CODE關掉,因為客戶的notebook會用自己的EC(ITE/WINDBON etc.)
