[PATCH 0/2] Add support for MIPS32r2 and CI20 to Yocto

[Vicente Olivert Riera]

Add support for the MIPS Creator CI20 machine. That board has a MIPS32r2
architecture so we also add support for that.

[PATCH 2/2] Add MIPS Creator CI20 machine

[Vicente Olivert Riera]

Add support for the MIPS Creator CI20 machine. You will need to build a
working kernel for this board using this kernel repository on GitHub:

  https://github.com/MIPS/CI20_linux

More information about this board can be found at:

  http://elinux.org/MIPS_Creator_CI20

All of the meta-yocto-bsp reference machines are using the kernel, and
kernel version of linux-yocto* so we can ensure a consistent update
cadence and set of features.

Something that I'd like to see continue.

I can see how the ability to re-use the tune files makes sense, but
the BSP should follow the format and structure of the existing ones,
otherwise, the value in pulling it into the common layers isn't there.

What Bruce said.  You've a specific machine that needs a specific
kernel, so this can happily live on as a Yocto-compatible BSP layer
outside of meta-yocto.

Hi Vicente,

there is already some support for mips32r2 (see
include/tune-mips32r2.inc) in oe-core master.
It looks like your patch is extending it so please rebase and resend
the patch to openembedded-core@lists.openembedded.org for review.

Thanks

Andrea

Yeah, I have noticed there is support for mips32r2 hard-float in Yocto's 
master branch. I was cloning the Daisy branch.

mips32r2 hard-float is all I need, so by now I'm not going to make any 
change to that file.

Thanks.
