I haven't run sbsa-ref for quite a while, but when I tried to today I
got an alignment fault in BootLogoLib.
Don't we disable alignment checking in EDK2 so we should never get
alignment faults?
I'm using edk2 commit aa99d36be9ad68d8d0a99896332a9b5da10cf343, with
commit 05ad1440b8428b0ade9b8e5c01469adb8fbf83e3 and booting
qemu with:
qemu-system-aarch64 -M sbsa-ref -cpu neoverse-n1 -m 8g -pflash
../Build/SbsaQemu/NOOPT_GCC/FV/SBSA_FLASH0.fd -pflash
../Build/SbsaQemu/NOOPT_GCC/FV/SBSA_FLASH1.fd -nographic -serial
mon:stdio -s
The crash happens when it tried to call GraphicsOutput->Blt.
| 208 if ((DestX >= 0) && (DestY >= 0)) { │
│ 209 if (GraphicsOutput != NULL) { │
│ > 210 Status = GraphicsOutput->Blt ( │

│ 212 Blt, │
│ 213 EfiBltBufferToVideo, │

│ 215 0, │
│ 216 (UINTN)DestX, │
