* Update to the latest PSP release (version 04.06.00.10) of the 3.2 kernel. * Rename recipe to match meta-ti kernel recipe naming convention. * Use in tree defconfig instead of providing a separate defconfig. These defconfigs were the same anyway. * Add additional crypto patches that were needed to fix suspend and resume issues. Signed-off-by: Franklin S.
