I try to port Kernel to custom MPC860 board. BSEIP architecture is close to my board. I used pROBE to load zvmImage on my board . ELF loader put .text section straight into 0x180000. With current head.S you lose value of R7 which should contain zImage length. I fixed it and I pass to Kernel R3 through R7 registers with valid context.
Still, nothing happen. In log_buf I see that kernel reports 0 K ( and some negative values ) memory allocation for its buffers and pages. The question is what else, besides R3-R7 wee need to pass to kernel to make it work? I assume that MMU and other hardware already set up. Any idea are welcome.
