Subject: microblaze: Cleanup linker script using new linker script macros.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8cc11f5ab5384dad6c63905f71882e65cd70b7b7;p=deliverable%2Flinux.git

microblaze: Cleanup linker script using new linker script macros.

I wasn't able to further clean up the linker script using the
INIT_DATA_SECTION macro because of the FIXME comment for the
.init.ramfs section; when that is resolved we should convert
microblaze to use INIT_DATA_SECTION.
