[PATCH] KERNELADDR and LOAD_BUFFER_POS shift

[Leonardo Rangel]

Hi guys,

last month we discussed about defining both KERNELADDR and  
LOAD_BUFFER_POS with
0x0 address and let prom_claim_chunk dinamically look for a free memory
chunck for TFTP buffer, kernel and initrd  
(http://ozlabs.org/pipermail/yaboot-devel/2007-October/000187.html)

This way, I was able to load big kernels/initrds and also zImages.initrd
(ie: rhel5 installation zImage - ppc64.img, which has 7.7MB).

Here is a patch for it. It was built over HEAD + the following patches:

Thanks and regards,
