9 | * Note on how mapped kernels work: the text and data section is | ||
10 | * compiled at cksseg segment (LOADADDR = 0xc001c000), and the | ||
11 | * init/setup/data section gets a 16M virtual address bump in the | ||
12 | * ld.script file (so that tlblo0 and tlblo1 maps the sections). | ||
13 | * The vmlinux.64 section addresses are put in the xkseg range | ||
14 | * using the change-addresses makefile option. Use elfdump -of | ||
15 | * on IRIX to see where the sections go. The Origin loader loads | ||
16 | * the two sections contiguously in physical memory. The loader | ||
17 | * sets the entry point into kernel_entry using a xkphys address, | ||
18 | * but instead of using 0xa800000001160000, it uses the address | ||
19 | * 0xa800000000160000, which is where it physically loaded that | ||
20 | * code. So no jumps can be done before we have switched to using | ||
21 | * cksseg addresses. | ||
