From: Simon Glass Date: Tue, 2 Jun 2015 17:08:20 +0000 (-0600) Subject: arm: Add ENTRY/ENDPROC to private libgcc functions X-Git-Tag: v2015.07~27^2~6 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=1251d51ca587431d07fb37fecb86b21db682e250;p=u-boot arm: Add ENTRY/ENDPROC to private libgcc functions When CONFIG_SYS_THUMB_BUILD is defined these functions may be called from Thumb code. Add the required ENTRY and ENDPROC bracketing so that BLX is used to call these ARM functions, instead of plain BL, which will fail.
