[PATCH 0/2] riscv: Fix missing select CACHEMAINT_FOR_DMA

[Jonathan Cameron]

The drivers/cache/Kconfig menu was changed to a menuconfig so as to be able
to hide the menu for non RISCV. The select of drivers under the original
menu were broken as the menuconfig itself could be disabled.  Fix this by
adding SELECT CACHEMAINT_FOR_DMA alongside the driver specific symbol
selects.

[PATCH 1/2] riscv: ERRATA_STARFIVE_JH7100: Fix missing dependency on new CONFIG_CACHEMAINT_FOR_DMA

[Jonathan Cameron]

The Kconfig menu entry was converted to a menuconfig to allow it to be
hidden for !CONFIG_RISCV. The drivers under this new option were selected
by some other Kconfig symbols and so an extra select CACHEMAINT_FOR_DMA is
needed.

I assume Conor will take the two patches in this series?

If not, please let me know, and I will queue it in renesas-fixes.
Thanks!
