| |
The sifive_l2_cache.c is in no way related to RISC-V architecture memory management. It is a little stub driver working around the fact that the EDAC maintainers prefer their drivers to be structured in a certain way that doesn't fit the SiFive SOCs.
Move the file to drivers/soc and add a Kconfig option for it, as well as the whole drivers/soc boilerplate for CONFIG_SOC_SIFIVE.
