[oe] ARM bootloaders (Zaurus) and CMDLINE

I'm trying to understand in details the boot-process and the changes
between 2.4 and 2.6 kernels.

The idea is to read the mtdparts passed by the Zaurus bootloader
(angel) with a 2.6 kernel.

I found two threads which shed some light:

http://lists.gnu.org/archive/html/qemu-devel/2007-07/msg00344.html
https://kerneltrap.org/mailarchive/linux-kernel/2007/10/25/355025/thread

The question is simple: is it possible to apply the
CONFIG_SHARPSL_BOOTLDR_PARAMS patch to the 2.6 kernels?

We'd need this in the kexecboot-kernel, to be able to recognize the
mtdparts passed in /proc/cmdline. This is actually working only with
u-boot.

Other solution would be a raw read of the nand addresses and a
subsequent edit of the CMDLINE params passed by the kexecboot kernel
to the launched kernel.

Any advice?

TIA

Andrea
