[PATCH v4 1/3] Convert CONFIG_SYS_L2_PL310 to Kconfig

Philip Oberfichtner pro at denx.de
Wed Aug 17 11:06:09 CEST 2022 

This converts CONFIG_SYS_L2_PL310 to Kconfig.

For omap2 and mvebu the 'select SYS_L2_PL310' locations were
determined using ./tools/moveconfig -i CONFIG_SYS_L2_PL310.

For mx6 I manually chose ARCH_MX6 as 'select' location. The
correctness has been verified using

	$ ./tools/moveconfig.py -f ARCH_MX6 ~SYS_L2_PL310 ~SYS_L2CACHE_OFF
	0 matches

That means whenever an ARCH_MX6 board had SYS_L2_PL310 disabled, this
was correctly reflected in SYS_L2CACHE_OFF. Thus it's safe to insert
the 'select' statement under ARCH_MX6.

I wonder if we could further reduce the diffstat by using 'select' for
all the socfpga boards. I did not find an appropriate way - I'm open for
suggestions, though.

Changes in v4:
        - Reduce diffstat by using 'select' statements for omap2, mvebu
          and mx6 based boards

Changes in v3:
        new
