The is not a u-boot question but a question about u-boot source code.
In file cpu/ppc4xx/start.S, the first line for 405GP is:
addi r4, r0, 0x0000
I think the purpose of this line is to set r4 as 0x0000, but where is r0
set? Is it supposed to be 0 when the code is started?
Also, why not simply use li r4, 0x0000. Any difference?
