Subject: sh: unify sh2/sh3/sh4 linker scripts
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=afc3929fac2ab5c2c3396ceed1bd7585c3b33cc2;p=u-boot.git

sh: unify sh2/sh3/sh4 linker scripts

The linker scripts of sh2/sh3/sh4 are almost the same.
The difference among them is essentially only one line.

They can be consolidated into a single file, arch/sh/cpu/u-boot.lds
by re-writing the diffrent line as follows:

	KEEP(*/start.o	(.text))
