My bisector fingered the commit 41f890164bc201f69841309c6b55e24c64121960 "ArmPkg/Mmu: Fix literal number left shift bug". I've tried to use the DEBUG firmware but didn't get any output at all. The guest has been created with 512MB in one memory bank (0x40000000-0x60000000). The binary are loaded at: UEFI firmware: 0x40080000 DTB: 0x48000000 Does anyone have any insight what could go wrong?
