FYI - I'm using version 2.4.18 of the linux
kernel with the ppc patches.

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
