FWIW, the "snds" port is for the Samsung S3C4500/4510 ARM7 parts and
supports the CACHE macros. I haven't looked at it in ages, so I don't
know what state it's in. Those parts are so old that I doubt anybody
cares enough to re-write the HAL to use any sort of generic ARM7
support. (They are still selling the '4510, but the '4500 died ages
ago.)
