src/sys/arch/arm/arm32: bus_dma.c
Log Message:
A few bus_dmatag_subregion fixes
- return EOPNOTSUPP if min_addr isn't less than max_addr
- fix the subset check to ensure that all the ranges in the parent tag are
within the {min,max}_addr range. If so we can just continue to use the
parent tag.
- when building the new ranges read the parent tag range rather than un-
initialised memory.
- remove the max_addr != 0xffffffff check - the overflow should be handled
by the unsigned arithmetic for arm32.
- add a KASSERT
- add comments
