PATCH v3 1/1 imximage: Remove failure when no IVT offset is found

From: Fabio Estevam <[email protected]>

Sometimes imximage throws the following error:

CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
CFGS board/freescale/vf610twr/imximage.cfg.cfgtmp
MKIMAGE u-boot-dtb.imx
Error: No BOOT_FROM tag in board/freescale/vf610twr/imximage.cfg.cfgtmp arch/arm/mach-imx/Makefile:100: recipe for target 'u-boot-dtb.imx' failed

Later on, when running mkimage for the u-boot.imx it will succeed in finding the IVT offset.

Looks like some race condition happening during parallel build when processing mkimage for u-boot-dtb.imx and u-boot.imx.

A proper fix still needs to be implemented, but as a workaround let's remove the error when the IVT offset is not found.

It is useful to have such message, especially during bring-up phase, but the build error that it causes is severe, so better avoid the build error for now.

The error checking can be re-implemented later when we have a proper fix.

As discussed, applied as fix for the release - thanks !

I think the real problem here is that the command to produce an imx from a bin file:

%.imx: %.bin

        $(Q)$(MAKE) $(build)=arch/arm/mach-imx $@

Creates, as part of the command, a temp file, imximage.cfg.cfgtmp. If two or more images are made, they both create temp files with the same name. The "CFGS" commands can run in parallel with each other and with the "MKIMAGE" that uses the cfgtmp file they both produce.

Usual make practice would dictate that when creating intermediate files, give them unique names, otherwise the operation can not be run in parallel on different inputs.

I think the original idea was that all the imx image targets would share a common cfgtmp file. But this doesn't work since each imx image is created via an independent submake.
