Marek, you can try my repository at 
https://github.com/willswang/u-boot-ath79,
I have fixed the compiling issue about headers.
I'm very sorry about this compiling error, my work tree have a residual 
symbol
link between arch/mips/include/asm/arch and 
arch/mips/mach-ath79/include/mach.
it was not removed when i executed "make clean" to rebuild,  so, my 
compiling
didn't discover this problem before this. now i clone this remote branch 
into a new
location and find this issue.
