Subject: omap3: make get_board_rev() function weak
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=715462dd7ec56f2410a98a4cd8fe8203132871dd;p=project%2Fbcm63xx%2Fu-boot.git

omap3: make get_board_rev() function weak

Current get_board_rev() function returns a hard coded value which is
obviously incorrect for the majority of boards.
Allow boards to provide a correct implementation by making this function
weak.
