- tms34020: Upgrade data bus to 32 bits and add preliminary masking for 16-bit operations
- tms34010, tms34020: Eliminate pure 8-bit read/write bus accesses (these are always read-modify-write, even if aligned)
- btoads, midxunit: Use 8-bit handlers for NVRAM, reducing size to 8192 bytes
- midwunit, midxunit: Eliminate dependencies on midtunit driver
This effectively reverts b380514764 and
c24473ddff, restoring the state at
598cd52272.
Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.
