Hello

I have ported the following drivers: watchdog, interrupt, clock/reset,
i/o pins, memory card; and implemented C906-specific cache management
functions.

So in September I could boot from MFS, get a shell and mount the MMC.
But I could not boot directly from MMC and I stalled there.

Also I had to disable T-Head memory extensions in the bootloader. I
don't know if other C906-specific things are needed.
