Yes, I use the mpc8xx.2.2.13.tgz to compile the kernel "zImage".
Do you mean that when I download the kernel "zImage" to RAM address 0x100000
on our own board (but not mbxboard) , and jump to 0x100000, It will
automatically run the uncompress program to copy and decompress the kernel to
0x200000, then jump to 0x200000, the decompressed kernel will boot, right ?
