[PATCH] Grub2 running address on PowerPC64

[PATCH] Grub2 running address on PowerPC64

[Manoel]

[-- Attachment #1: Type: text/plain, Size: 580 bytes --]

OF uses the address 0x4000 as base-load (as stated in NOTE section added
by grub-mkelfimage) and grub uses 0x10000 as running address, thus
causing segment overlapping which leads to grub2 unable to load its
modules.

This patch moves the running address to 0x200000 to prevent overlapping,
its the same address used by Yaboot and is know to work well.

the makefile must be regenerated using the command:
 $ ruby genmk.rb < conf/powerpc-ieee1275.rmk> conf/powerpc-ieee1275.mk

  The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
  how) you may access your data; but nobody's threatening your freedom: we
  still allow you to remove your data and not access it at all."
