[U-Boot] [PATCH 4/5] Kconfig: mx6ull: Deselect MX6UL from CONFIG_MX6ULL
From: Breno Lima breno.lima@nxp.com
MX6UL contains features that MX6ULL doesn't support. Deselect CONFIG_MX6UL and select SYS_L2CACHE_OFF and ROM_UNIFIED_SECTIONS.
The motivation for doing this change is that MX6UL supports CAAM and MX6ULL does not.

While I agree with the idea of the change in general, it must be done more carefully! There are several places where we rely that CONFIG_MX6ULL selects CONFIG_MX6ULL, e.g. include/configs/mx6_common.h arch/arm/include/asm/arch-mx6/imx-regs.h arch/arm/include/asm/mach-imx/regs-lcdif.h
I see that this patch already got merged... So I guess we either fix all those places before the release, or we revert this patch...

You are right.

Thanks

Ouch...
It is much more as the initial goal of the patch. This breaks MX6ULL.
The idea to add features instead of global SOC define is good, rather we suffer from previous development, when we bound bunches of features simply to the SOC type.

Agree - I am waiting for Breno's answer, but if we have a generally agreement I tend to revert this until this change will be properly handled.
Best regards, Stefano

I have already sent a fix for this problem: https://patchwork.ozlabs.org/patch/854371/
It has been successfully tested by Breno and Peng.
