[U-Boot] [PATCH 2/6 V2] sh: make the linker scripts more generic
Jean-Christophe PLAGNIOL-VILLARD
plagnioj at jcrosoft.com
Thu Jun 4 12:06:44 CEST 2009
currently we need to sync the linker script enty and TEXT_BASE manualy
and the reloc_dst is based on it
instead provide it now from the ldflags
tested on r2dplus
