Subject: [PATCH v2 2/2] frv: clean up linker script using new linker script macros.
From: Nelson Elhage <nelhage@...lice.com>
This is largely a straightforward conversion. The patch results in
fewer output sections, and some data being reordered, but should have
no functional impact.
Also, note that this patch moves some data (namely, init_task and
cacheline-aligned) inside [_sdata,_edata].
Because frv already builds using -ffunction-sections -fdata-sections,
we can't use BSS_SECTION or RW_DATA_SECTION yet, since they do not
currently include the required .bss.* and .data.* sections.
