with current master branch in git://git.denx.de/u-boot-mips.git you can drop the endianess flags which are now handled in arch/mips/config.mk
Ok, I have done what you ask for. But I didn't find where does
CONFIG_SYS_LITTLE_ENDIAN or CONFIG_SYS_BIG_ENDIAN define. Could you tell where should I put them? It seem that putting it in qemu-mips64.h doesn't affect building flags.
currently we cannot use interrupts or setup any interrupt handlers in u-boot-mips. Please leave those functions empty.
calling a C function is not supposed to work here because no stack pointer has been setup yet. I checked with Sourcery 2011.09 and 2012.03. The stack is always utilized in cache_probe. Either you rewrite the cache_probe function in assembler or you use the existing config options and you could drop the cache probing.
I'm afraid I don't say clearly just now. I mean could I call cache_probe
in checkboard()?
