I tested the full series on the following OMAP1 boards: ams-delta,
nokia770, osk, palmte and sx1 (QEMU only).

Apart from the earlyprintk breakage, everything seemed to work OK.

A minor note, zImage grows about 50 KB with a minimal kernel config. This
is not yet critical, there's still about 7% headroom on 770 to the 2 MB
bootloader limit on my setup. Also the decompression time is approaching
the hardcoded watchdog timeout...
