Please don't top-post.

Did you add "earlyprintk" to your kernel command line
like the EARLY_PRINTK menuconfig help text suggests?

arch/arm/mach-at91/include/mach/debug-macro.S also suggests
the LL debug output goes to AT91 debug unit not to normal UART
(not sure about this, I don't know much about AT91).
Did you try to dump __log_buf using JTAG?
