From: Daniel Schwierzeck Date: Tue, 12 Feb 2013 21:22:13 +0000 (+0100) Subject: MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation X-Git-Tag: v2013.04-rc1~46^2~2 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=28875e2c4731296ee7ed645d07f1c28c0301f1c4;p=u-boot MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation Use the newly introduced symbol __image_copy_end as end address for relocation of U-Boot image. This is needed for dynamic relocation added in later patches. This patch obsoletes the symbols uboot_end and uboot_end_data which are removed.
