This is a good first start. But I think there's a few things that need tweaking. First, we don't want to globally turn off dcache, but it does need to be migrated to Kconfig (so we know if it's enabled or not). Second, we should instead use CMD_CACHE and the 'dcache' command to disable dcache prior to running the FreeBSD loader. Then we make sure that the generic distro feature has CMD_CACHE if !SYS_DCACHE_OFF (and !SYS_ICACHE_OFF). Thanks! -- Tom
