[U-Boot] [PATCH V5 1/2] ARM: fix linker file for newer ld support
Albert Aribaud
albert.aribaud at free.fr
Mon Nov 15 21:46:03 CET 2010
older ld emitted all ELF relocations in input sections named
.rel.dyn, whereas newer ld uses names of the form .rel*. The
linker script only collected .rel.dyn input sections. Rewrite
to collect all .rel* input sections.

V1 Initial submission
V2 arm926ejs: added ALIGN between bss and .rel.dyn sections
tx25: removed GOT and datarel output sections
tx25: fixed typo in config file commit message
V3 arm926ejs: overlaid .bss and .rel.dyn sections
tx25: overlaid .bss and .rel.dyn sections
V4 arm926ejs and tx25: fixed overlay
tx25: removed third patch as u-boot size remains small enough
V5 added u-boot.lds/start.S fix for arm1136, arm1176, pxa, armv7.
