Hi,
We are just moving to the linux and gnu world from other RTOS. First thing we try to port our own bootloader to U-boot for our MPC8xx board.
Some "naive" questions about u-boot for MPC8xx, the definition of some macro in ppc_asm.tmpl. Can anyone there explain them to me please?
1) In GET_GOT(x) what does " lwz r0,0b-1b(r14) ;" do? what does "0b-1b" stands for, or the meaning of the syntax? why move the content of the memory pointing by LR?
Thanks for the helps!!
