These are some initial patches to bugs I found attempting to get a XIP kernel working on hardware: - 32-bit VexRiscv processor - kernel in SPI flash, at 0x00200000 - 16MB of RAM at 0x10000000 - MMU enabled The system isn't actually booting yet; but at least the initial memory management setup completes with these patches as opposed to crashing almost straight away.
