In the arch/ppc/boot directory, one of the linker
options is "-Ttext 0x00800000".
What does this mean ?
The base virtual address of the kernel is c0000000.
I've been using my own hand-rolled bootloader to
load the zImage.bin file into an address allocated
by the VxWorks malloc and jumping to that address.
Second question.
arch/ppc/boot/simple/head.S says it expects the load address
in r3. It seems strange that it would need its own (start)
starting address. What is this routine expecting ?
Regards,
Bob Beck
