Subject: [PATCH 3/4] clearfog: enable distro boot code
|
||
|
|
|
||
|
|
load addresses start at 0x02000000, leaving enough space for fdt,
|
||
|
|
boot scripts and ramdisk at the end.
|
||
|
|
Only boot from mmc, the other options are not in working order.
|
||
|
|
Removed *_high variables in good faith. They can be re-added with sane
|
||
|
|
values when, and if required.
|
||
|
