[-- Attachment #1: Type: text/plain, Size: 6944 bytes --]
Initrd load address is too low, it conflicts with kernel load
address:
rom: requested regions overlap (rom phdr #0:
/tmp/vmlinux-debian-6.0.4-sparc64. free=0x0000000000742519,
addr=0x0000000000400000)
rom loading failed
Fix by making the initrd address variable, load initrd after kernel
image. Use 64 bit variables instead of longs or 32 bit types.
