[oe] [PATCH] Userspace ATAG support for kexec

[Uli Luckas]

This patch for the kexec userspace tool adds support for propperly setting up 
ATAGs for the kexeced kernel. 
It uses information exported via /proc/atags to preserve all ATAGs except 
ATAG_INITRD, ATAG_INITRD2 and ATAG_CMDLINE. The ATAG_INITRD2 and ATAG_CMDLINE 
tags are set up according to command line options.
To start a kernel with nfs root via the usb gadget device for example a 
command line like this could be used:
kexec -l zImage --append="root=nfs nfsroot=192.168.1.1\:/oe-linux-rootfs 
ip=192.168.1.2:192.168.1.1:192.168.1.1:255.255.255.0:gadget:usb0:off rw"

This patch should be applied ontop of openembedded's "kexec-tools-arm.patch".
The patch posted in "[PATHC] ATAG export for the linux kernel" needs to be 
applied to the running kernel.

regards,
Uli Luckas
