According to the doc, you cannot use memory under 0x8000. So,
I've prepend an AIF header that tells the boot loader to copy image
to 0x8000, then I've put into zero-init zone the part of code to set
r0,r1 and put off mmu, then I should jump to 0x8000
But I'm not sure zero-init code is executed in that case.
Anyway, by initialisiing UART in uncomp_setup_arch() , I now get
"Uncompressing Linux...done"
and "now booting the kernel.",
but then .... nothing
I've also tried by adding the bootstrap instructions to the beginning
of head.S, but It doesn't work neither better nor bader
