[U-Boot-Users] [GIT PULL] MIPS updates

[Shinya Kuribayashi]

Dear Wolfgang,

please pull MIPS updates. 2 patches are there. One fixes a build failure
caused by absence of dcache_enable(). The other is for a better handling
of gas minor version (this isn't a kind of bug fix, but I'd like to push
this for 1.3.3 release. Ok?).

Each patch has not been posted to u-boot-users yet, so they will follow
this mail. Please review (and apply).

thanks,

  Shinya

[U-Boot-Users] [PATCH][MIPS] cpu/mips/cache.S: Add dcache_enable

[Shinya Kuribayashi]

Recent bootelf command fixes (017e9b7925f74878d0e9475388cca9bda5ef9482,
"allow ports to override bootelf behavior") requires ports to have this
function.

[U-Boot-Users] [PATCH][MIPS] cpu/mips/config.mk: Fix GNU assembler minor version picker

[Shinya Kuribayashi]

Current trick to pick up GNU assembler minor version uses a dot(.) as a
delimiter, and take the second field to obtain minor version number. But
as can be expected, this doesn't work with a version string which has
dots more than needs.

Here's an example:

$ mips-linux-gnu-as --version | grep 'GNU assembler'
GNU assembler (Sourcery G++ Lite 4.2-129) 2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | cut -d. -f2
2-129) 2
$

This patch restricts the version format to 2.XX.XX... This will work
in most cases.

$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+'
2.18.50.20080215
$ mips-linux-gnu-as --version | grep 'GNU assembler' | egrep -o '2\.[0-9\.]+' | cut -d. -f2
18
$
