[PATCH for-5.0 1/8] q35: implement 128K SMRAM at default SMBASE address

2019-12-04 Thread Igor Mammedov
Use commit (2f295167e0 q35/mch: implement extended TSEG sizes) for inspiration and (ab)use reserved register in config space at 0x9c offset [*] to extend q35 pci-host with ability to use 128K at 0x3 as SMRAM and hide it (like TSEG) from non-SMM context. Usage: 1: write 0xff in the register
