[Buildroot] [PATCH 1/2] openblass: drop SSE_GENERIC target

[Buildroot] [PATCH 1/2] openblass: drop SSE_GENERIC target

[Peter Korsgaard]

Fixes #10856

The SSE_GENERIC target fails to build with a "sgemm_kernel.o: No such file
or directory" error. Several upstream bug reports exist for this:

https://github.com/xianyi/OpenBLAS/issues/502
https://github.com/xianyi/OpenBLAS/issues/685

In both cases, upstream suggests using a different target definition
instead.  E.G.  from issue 685:

You may use NORTHWOOD on x86: make TARGET=NORTHWOOD that uses SSE2
instructions.  It's very hard to find non-SSE2 x86 CPUs today.  For x86-64
use the PRESCOTT target

So drop the SSE_GENERIC target.  The only x86_64 variant we support not
covered by a more specific openblas target is the default variant, nocona.

Nocona was a Xeon variant of the P4 "Prescott" architecture, so use the
PRESCOTT openblas target:

[Buildroot] [PATCH 2/2] openblas: bump version to v0.2.20

[Peter Korsgaard]

Drop 0001-Complete-support-for-MIPS-n32-ABI.patch as it is now upstream and rebase
0002-Makefile.arm-remove-march-flags.patch.

Also add a hash for the license file.

 Actually, I think BR2_x86_corei7_avx is not covered either. And BR2_x86_jaguar.

 These openblas targets really are an unmaintainable mess...

This is going to be the most useless e-mail, but here is a minor nit:
missing closing bracket.

I'm just going to add a few more sentences here, just to pretend this
e-mail is not just about this small nit. But I don't have much else to
say about this patch. Oh well, the length of this text starts to justify
this e-mail. I can probably stop here, and put my usual closing Best
regards, so let's do this.

Best regards,

Thomas

corei7_avx is:

default "SANDYBRIDGE"  if BR2_x86_corei7_avx

But jaguar indeed isn't. Jaguar is in the bobcat family so I'll add a
default "BOBCAT" entry for it:

Indeed :/
