> Subject: [PATCH] arm926ejs: timer: Replace bss variable by gdr
> 
> Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
> values in the arm926ejs timers implementation.
> 
> The usage of bss values in drivers before initialisation of bss is
> forbidden.
> In that special case some data in .rel.dyn gets corrupted.
> 
> This patch is similiar to the patch Dirk Behme posted
> for the armv7/omap-common/timer.c and added suggestions
> from Reinhard Meyer.
> 
> Tested on the arm926ejs mx27 based magnesium board
> Tested on the arm926ejs kirkwood based suen3 board
