[U-Boot] [PATCH] ARC: change the default CROSS_COMPILE for ARC

[U-Boot] [PATCH] ARC: change the default CROSS_COMPILE for ARC

[Masahiro Yamada]

As doc/README.ARC says, pre-build ARC toolchains are available at
the Synopsys GitHub page.

The bin files are prefixed with arc(eb)-buildroot-linux- for earlier
releases, but with arc(eb)-snps-linux- for the latest releases
(arc_gnu_2014.12_prebuilt_*).

For all the releases, the symbolic link, arc(eb)-linux-* is also
prepared for each bin file, so it can be used as the default
CROSS_COMPILE regardless of the toolchains version.

I would propose to use even simpler and more universal prefix which
could be used with both ARC pre-built toolchains, your own toolchain
built by Buildroot or even pre-built Buildroot toolchain
(http://autobuild.buildroot.org/toolchains/tarballs/br-arcle-hs38-full-2015.02.tar.bz2):
 [1] "arc-linux-" for little-endian
 [2] "arceb-linux-"

Care to re-send your patch or I may do that change myself?

I've posted v2.
Thanks for pointing this out!
