Hi,
This patch maintains Marvell PJ4 cores pipeline description.
Run arm testsuite on arm-linux-gnueabi and no extra regressions are found.
* config/arm/marvell-pj4.md: New marvell-pj4 pipeline description.
* config/arm/arm.c (arm_issue_rate): Add marvell_pj4.
* config/arm/arm-cores.def: Add core marvell-pj4.
* config/arm/arm-tune.md: Regenerated.
* config/arm/arm-tables.opt: Regenerated.
* doc/invoke.texi: Added entry for marvell-pj4.
Thanks!
P.S. I create the patch from revision 187308, but this revision is unable to build successfully, then I apply this patch to revision 187623 and successfully build and pass the testsuite.

This command line option should also be added to BE8_LINK_SPEC similar
to what's done for the other v7-a cores.
Ok with that change.

I take the blame for not doing this back then, but I suggest the
resource names be properly qualified, similar to most recently added
pipeline descriptions, e.g. prepend resource/reservation names with
"pj4_" ("is" to "pj4_is", etc.)

marvell-pj4 is added to BE8_LINK_SPEC.
Modified patch is attached.
Thanks!

Another nit, I think the tune_marvell attribute now looks a bit
unneeded. You can just fold it into the "tune" clause of "generic_sched".

Sorry about the time it's taken to finish this patch up. I seem to have
missed this one in the review process.
I've now applied the attached patch after taking into account the recent
attribute changes and treated alu_reg and simple_alu_imm as you have
treated alu, rebased to trunk to fix up some small issues with
BE8_LINK_SPECS.
Additionally I've removed tune_marvell as that seems redundant at this
point of time - an additional attribute and testing that appears to be
unnecessary instead of just one more inequality test.
The only part I'm not sure about is how to treat the simple_alu_shift
category here , so a patch to handle them in the pj4 pipeline
description would be welcome.
Thanks
Ramana

the patch was missing the new file config/arm/marvell-pj4.md. Checked is as
obvious to restore the bootstrap.

Hi Ramana,
Attached is the patch for marvell-pj4.md to fix the simple_alu_shift category.
Thanks for your kindly help.
Cheers,
Yi-Hsiu, Hsu

Sorry about the time it's taken to finish this patch up. I seem to have missed this one in the review process.
I've now applied the attached patch after taking into account the recent attribute changes and treated alu_reg and simple_alu_imm as you have treated alu, rebased to trunk to fix up some small issues with BE8_LINK_SPECS.
Additionally I've removed tune_marvell as that seems redundant at this point of time - an additional attribute and testing that appears to be unnecessary instead of just one more inequality test.
The only part I'm not sure about is how to treat the simple_alu_shift category here , so a patch to handle them in the pj4 pipeline description would be welcome.
Thanks

In the future please submit patches with a Changelog entry. I've created
one for this patch as it needed a bit of splitting up given the
mis-commit earlier by doko.
So in this case I've now committed the following with the following
Changelog entry.
