[U-Boot] [PATCH 2/2] Changes to move hawkboard to the new infrastructure.
Sughosh Ganu
urwithsughosh at gmail.com
Mon Jan 9 19:28:49 CET 2012
This patch moves hawkboard to the new spl infrastructure from the
older nand_spl one. Making this change required some code refactoring
with a couple of davinci based platforms which use spl.
Removed the hawkboard_nand_config build option -- The spl code now
gets compiled with hawkboard_config, after building the main u-boot
image, using the CONFIG_SPL_TEXT_BASE. Modified the README.hawkboard
to reflect the same.
