Alex is write that this is due to the 32MB size limit on XIP kernel. This means build failure happens if too many configurations are enabled and the kernel gets too large. I just sent a series to lift the size restriction and fix this build failure: https://lore.kernel.org/lkml/cover.1715286093.git.namcao@linutronix.de/ Best regards, Nam
