To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".
Thanks to martin@ for the input on testing.
This is more flexible than the old acorn26 bus_space, which means that single
read/write operations are slower, but multi and region operations have the
potential to be faster, and particularly insane podules might be supportable.
In theory the acorn32 mainbus and podulebus code ought to be shareable, but
acorn26 needs the extra overhead of saving R14_svc on some operations so
I've made my own version for now. Also the acorn32 bus_spaces are a mess.
assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers. This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus. Thus, we don't do that
any more.
This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
matching names. This commit might include some private hacks that have been
lurking in my tree a while. They're all harmless, and this reduces the number
of gratuitous diffs I have to deal with.
