[U-Boot] [PATCH v5 6/7] Changes to move hawkboard to the new spl infrastructure
Christian Riesch
christian.riesch at omicron.at
Tue Jan 31 14:56:53 CET 2012
From: Sughosh Ganu <urwithsughosh at gmail.com>
This patch moves hawkboard to the new spl infrastructure from the
older nand_spl one.
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.
