1. Your lowlevel_init routine duplicates cache maintenance functions by Paul Burton
(please see commit 4a5d8898bca3e442b6 'MIPS: unify cache initialization code').

2. Can we select build for ar71xx from .config? I suppose 'No',
because the patch does not add any Kconfig option.

3. Can we put your arch/mips/mach-ath79/ar933x/serial.c into drivers/serial?

4. The patch is suffering from very very many unused macros in ar71xx.h.

5. The patch has whitespace errors, please see this git-am log:
