2009-07-08sh: unify linker scriptJean-Christophe PLAGNIOL-VILLARD
all sh boards use the same cpu linker script so move it to cpu/$(CPU) that could be overwrite in following order SOC BOARD via the corresponding config.mk tested on r2dplus Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nobuhiro Iwamatsu <iwamatsu.nobuhiro@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2009-07-08sh: make the linker scripts more genericJean-Christophe PLAGNIOL-VILLARD
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 Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Cc: Nobuhiro Iwamatsu <iwamatsu.nobuhiro@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2009-03-20Fix all linker script to handle all rodata sectionsTrent Piepho
A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-01-16sh: Fix compile error on lowlevel_init fileNobuhiro Iwamatsu
lowlevel_init of SH was corrected to use the write/readXX macro. However, there was a problem that was not able to be compiled partially. This patch corrected this. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
