I suggested another solution:
http://patchwork.ozlabs.org/patch/123074/
This has the disadvantage, as discussed in the thread, that the address
passed to mmap is not guaranteed to be returned.
This could be caught by an assert. The base address in the patch
(0x20000000) was choosen with respect to the typical process address
layout on x86 and x86_64 linux to avoid any conflict. Even when ASLR
causes this the u-boot binary could still be started using setarch with
ASLR disabled.
