Hi,
The following patchset adds support for 64bit little endian boot
wrapper. It is based on original code from Andrew Tauferner.
The first patches provide fixes for 64bit support. I also changed
the prom code to make it converge with the prom_init kernel code.
They have a lot in common and
This patch fixes warnings when the wrapper is compiled in 64bit and
updates the boot wrapper code related to prom to converge with the
kernel code in prom_init. This should make the review of changes easier.
The kernel has a different number of possible arguments (10) when
entering prom. There
This patch updates the wrapper code to converge with the kernel code in

This patch defines a 'prom' routine similar to 'enter_prom' in the
kernel.
The difference is in the MSR which is built before entering prom. Big
endian order is enforced as in the kernel but 32bit mode is not. It
prepares ground for the next patches which will introduce Little endian
order.
When entering the boot wrapper in little endian, we will need to fix
the endian order using a fixup trampoline like in the kernel. This
patch overrides the _zimage_start entry point for this purpose.

The code is only slightly modified : entry points now use the
FIXUP_ENDIAN trampoline to switch endian order. The 32bit wrapper
is kept for big endian kernels and 64bit is enforced for little

The linker script is generated using the kernel
