+Subject: [PATCH] imximage: Remove failure when no IVT offset is found
+
+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.
