3.16.65-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Michael Ellerman <mpe@xxxxxxxxxxxxxx> commit 2b874a5c7b75fdc90fdd1e2ffaa3ec5a9d21e253 upstream. This reverts the remains of commit b9ef7d6b11c1 ("powerpc: Update default configurations"). That commit was proceeded by a commit which added a config option to control use of BOOTX for early debug, ie. PPC_EARLY_DEBUG_BOOTX, and then the update of the defconfigs was intended to not change behaviour by then enabling the new config option. However enabling PPC_EARLY_DEBUG had other consequences, notably causing us to register the udbg console at the end of udbg_early_init(). This means on a system which doesn't have anything that BOOTX can use (most systems), we register the udbg console very early but the bootx code just throws everything away, meaning early boot messages are never printed to the console. What we want to happen is for the udbg console to only be registered later (from setup_arch()) once we've setup udbg_putc, and then all early boot messages will be replayed.
