I'm afraid that standalone support on MIPS is broken since we moved from 
manual symbol relocation to dynamic relocation. I've pushed a fix to 
git://git.denx.de/u-boot-mips.git branch 'fix_standalone_v1'. 

Could you retest with that branch? I'll send a patch series later.


At least it worked again on Malta board in Qemu:

$ qemu-system-mips -M malta -cpu 24Kc -m 256 -nographic -netdev user,id=ubtest,tftp=examples/standalone -device pcnet,netdev=ubtest -bios u-boot.bin
