[U-Boot] [PATCH 1/3] arm: Add SYS_L2CACHE_OFF Kconfig entry
To i.MX6UL, SYS_L2CACHE_OFF is selected, but there is no Kconfig entry for SYS_L2CACHE_OFF. Then "select SYS_L2CACHE_OFF" does not effect for i.MX6UL, which is not expected.
Since SYS_L2CACHE_OFF is mainly used by ARM architecture, add it to arch/arm/Kconfig.

Hi,
I worked this patch based on imx tree, since mainly for i.MX6UL. Then can this patch go through imx tree to avoid break i.MX6UL? This option does not impact others which defined CONFIG_SYS_L2CACHE_OFF in board header file.

There is no need to expose SoC choice to user, we already got the SoC according to the build target. So default "select MX6UL" for MX6UL_14x14_EVK target.

Hi Stefano,
From my side, I think we need to select MX6x for other TARGET_xx based
on MX6x. Later I'll do that work if you agree with my point.
From the long run, we can discard the MX6x, if we finally reach the goal
to support runtime check, but work to be done step by step:)

Discard MX6UL from CONFIG_SYS_EXTRA_OPTIONS, since we default select MX6UL for mx6ul_14x14_evk board.
