[PATCH 1/1] OpenRISC: Fix kernel build problem on OpenRISC

[anees]

Kernel build fails with error "target elf32-or32 not found"
This is due to the change in OpenRISC compiler prefix from "or12"
to "or1k". Add config options that set architecture output format
default to "or1k" but also allow user to select older prefix.

Tested with gcc version 4.9.1 uclibc

That means I'll have to use different toolchains for different kernel
versions, or hand-edit default configuration files to able to work
with the same toolchain. Both is, from a testing perspective,
quite annoying.

Maybe I should simply stop testing older kernels for openrisc
after this patch has been merged; that would be much easier.
Jonas, is that ok with you ?

Side note: I didn't drop it from Cc:, but the openrisc.net domain
name expired and appears to be for sale.

Also quite annoying would be
    $ grep OUTPUT_FORMAT .config 
    CONFIG_OUTPUT_FORMAT_TYPE="typo"

(Note the missing CONFIG_OUTPUT_FORMAT= line.)

What might be less annoying would be something (completely untested)
like:
    choice
	prompt "Architecture output format type"
	default OUTPUT_FORMAT_OR1K
	help
	  Choose "or12" if building kernel against an older toolchain
	  else leave the default "or1k".

    config OUTPUT_FORMAT_OR1K
	bool "or1k"

    config OUTPUT_FORMAT_OR12
	bool "or12"

    enchoice

    config OUTPUT_FORMAT
	string
	default "elf32-or1k" if OUTPUT_FORMAT_OR1K
	default "elf32-or12" if OUTPUT_FORMAT_OR12

> Jonas, is that ok with you ?

Would testing be easier if you'd be provided with two defconfig files?
Ie, one for "elf32-or1k" and "elf32-or12".

(Note that "elf32-or12" smells like a typo to me. Shouldn't that be
"elf32-or32"? If not, where does "elf32-or32" fir in this story?)

That's ominous.

(That patch also suggests that "or12" in the patch we're discussing here
is a typo.)

This is problem is present now for none months, apparently. Your patch
was supposed to be applied already (see
https://lkml.org/lkml/2014/9/22/36 ), but clearly nothing happened.
openrisc.net is for sale.

What's going on here?

openrisc.net is no more.... long story, not worth regurgitating.

Guenter's patch is the one to apply.  You can put my Acked-by: Jonas 
Bonn <jonas@southpole.se> on it.  Unfortunately, I'm not currently in a 
position to do anything meaningful with it, so please send it upstream 
directly via Andrew Morton's collection of assorted patches.

Jonas,

Looks like you are out for the time being, and we can not add Stefan
as maintainer (yet) because he doesn't have a signed key.

Wonder if I should step in as interim maintainer to handle urgent
requests like this one. Comments, thoughts, anyone ?

This is about a pretty major build issue, that's been known for ten
months now, isn't? If that's correct, this is not an urgent request, but
a chronic issue. So in that case anyone who cares about OpenRISC should
consider taking over. Because this looks like an orphaned architecture
to me.

Am I being too strict?

Those using the architecture simply apply the patch, or a similar patch,
or use the tree Stefan maintains at github.

Sure, we can wait until Stefan gets a public key and we can add him
as maintainer. I guess the active users use Stefan's tree at github
anyway.

The problem was already present when openrisc was introduced back in 2011;
see arch/openrisc/TODO.openrisc. I just tried to get it fixed to let me use
a more recent toolchain for my build tests.
