We were having an issue with the command "go addr" starting some binary images (like the linux kernel and others).
You are aware that Linux is supposed to be booted using the bootm command, aren't you?
Aubrey Li tracked this down to what appears to us as an issue in u-boot/common/cmd_boot.c:do_go which doesn't clear, or invalidate cache.
Why do you think this is a problem? Caches are flushed after loading an image.
Right now, we added this to our cvs, with an ifdef - if this is a common need for other architectures, we can take out the ifdef, and re-sumbit the patch.
It will be rejected...
+#if defined(CONFIG_BLACKFIN)
if(icache_status())invalidate_entire_icache();+#endif
This will just cause linker errors. There is no function invalidate_entire_icache() anywhere in U-Boot.
