From: Arnd Bergmann <arnd@arndb.de> The address range 0xfee00000-0xfeffffff is used for PCI and PCMCIA I/O port mappings, but OMAP1 has its static mappings there as well. Move the OMAP1 addresses a little higher to avoid crashing at boot.
This has the same problem I reported in 2019, with earlyprintk the system no longer boots: https://marc.info/?t=156530014200005&r=1&w=2 Tested on OSK and SX1/qemu. A.
