ARM: socfpga: select the PL310 erratum 753970 workaround

[PATCH] ARM: socfpga: select the PL310 erratum 753970 workaround

Posted by Pengpeng Hou 3 weeks, 6 days ago

ARCH_INTEL_SOCFPGA selects CACHE_L2X0 and several PL310 erratum
workarounds. The 753970 workaround is still conditioned on PL310, but that
Kconfig symbol no longer exists, so this one selection is always disabled.

Select PL310_ERRATA_753970 directly, consistently with the other PL310
workarounds required by the platform.

Fixes: fbc125afdc50 ("ARM: socfpga: Turn on ARM errata for L2 cache")
