[RFC PATCH v2 24/44] i386/tdx: Add MMIO HOB entries

2021-07-07 Thread isaku . yamahata
From: Sean Christopherson Add MMIO HOB entries, which are needed to enumerate legal MMIO ranges to early TDVF. Note, the attribute absolutely must include UNCACHEABLE, else TDVF will effectively consider it a bad HOB entry and ignore it. Signed-off-by: Sean Christopherson Signed-off-by: Isaku
