[U-Boot] [PATCH] common: image: Allow mkimage to build a uImage for extensa

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

Currently we get the following failure when trying to build a uImage for 
extensa:

$ ./tools/mkimage -A xtensa

Invalid CPU Type - valid names are: alpha, arm, x86, ia64, m68k, microblaze,
mips, mips64, nios2, powerpc, ppc, s390, sh, sparc, sparc64, blackfin, avr32,
nds32, or1k, sandbox, arm64

Add an entry for extensa so that a uImage can be built.

Hi Fabio,

Thanks for the patch, but the name is actually 'xtensa' (without the 
'e'). Would be great if you could change that.

Thanks,
-Chris

[U-Boot] [PATCH] common: image: Allow mkimage to build a uImage for extensa

[Wolfgang Denk]

Dear Fabio Estevam,

Is this "xtensa" or "extensa"?

And which actual architecture would that be?  I cannot find any
architecture support for xtensa in U-Boot mainline, so why should we
add image support for it?

If you plan to add support for this architecture, then please submit
this patch as part of the series that adds such architecture support.

Best regards,

Wolfgang Denk

It is xtensa, sorry.

Ok, understood.

Looks like the quick fix is for Michael/Geert do not build uImage for
xtensa on their automated build environments.

What would you do with an uImage file when there is no U-Boot to load
it?

Michael's build system builds uImage for xtensa:
http://kisskb.ellerman.id.au/kisskb/buildresult/10665903/

,so it makes more sense simply not to build uImage for such architecture.

Hi,

I have a port for the Xtensa architecture ready, and it would be great 
if you could include it in the mainline tree. I still have to finish 
another project, but could start sending patches for RFC to this mailing 
list in a week or two.

Thanks,
-Chris

It just runs "make".

The decision about building a uImage must be in the .config somewhere.

This failure is for allnoconfig, so presumably there is something like a
CONFIG_DONT_BUILD_UIMAGE which is getting set to n by allnoconfig. If you can
tell me what that option is I can force it back on (I think).

cheers

It seems that xtensa uses an out of tree U-boot port then.

Chris mentioned that he plans to upstream xtensa u-boot support.

arch/xtensa/boot/boot-uboot/Makefile does force the uImage to be generated.
