Progress: * UM-2 [QEMU upstream maintainership] - Before the QEMU 7.0 release we tried to land a bug fix which corrected the handling in our PSCI emulation of calls where the function ID is unrecognized -- these are supposed to return an error code. The bugfix turned out to cause regressions for some boards when running guest code at EL3 (because those boards were incorrectly enabling PSCI emulation in that situation). Sent a patchset that fixed those boards so we don't enable PSCI when running EL3 guests, and re-introduced the original PSCI bugfix. - Fixed various bugs in the highbank/midway boards discovered in the process of writing and testing the above patchset. (These two boards were the most complicated to fix.) - More code review, and sent out an arm pullrequest - Small handful of other minor patches
