Hard to tell me how many of those things are missing in QEMU and how 
many in EDK2 we use as firmware.

SBSA-ACS failures:

GIC ITS is missing (Shashi Mallela works on it):

 102 : If PCIe, then GIC implements ITS  : Result:  --FAIL-- 1
 104 : GIC Maintenance Interrupt         : Result:  --FAIL-- 1


System timers are not present in GTDT so few more tests are not run:

 206 : SYS Timer if PE Timer not ON      : Result:  --FAIL-- 1
       PE Timers are not always-on.
 207 : CNTCTLBase & CNTBaseN access      : Result:  -SKIPPED- 1
       No System timers are defined
 505 : Wake from System Timer Interrupt  : Result:  -SKIPPED- 1
       No system timers implemented


There is no SMMU present so SMMU and IO virtualization tests are not 
run. This one is probably related:

 605 : Memory Access to Un-Populated addr: Result:  --FAIL-- 1
       Memory access check fails at address = 0x104C0000
