- * Perform "ISA" memory and IO accesses. The EBSA110 has some "peculiarities"
- * in the way it handles accesses to odd IO ports on 16-bit devices. These
- * devices have their D0-D15 lines connected to the processors D0-D15 lines.
- * Since they expect all byte IO operations to be performed on D0-D7, and the
- * StrongARM expects to transfer the byte to these odd addresses on D8-D15,
- * we must use a trick to get the required behaviour.
- *
- * The trick employed here is to use long word stores to odd address -1. The
- * glue logic picks this up as a "trick" access, and asserts the LSB of the
- * peripherals address bus, thereby accessing the odd IO port. Meanwhile, the
- * StrongARM transfers its data on D0-D7 as expected.
- *
- * Things get more interesting on the pass-1 EBSA110 - the PCMCIA controller
- * wiring was screwed in such a way that it had limited memory space access.
- * Luckily, the work-around for this is not too horrible. See
- * __isamem_convert_addr for the details.

Russell said that he is no longer using this machine, and it seems that nobody else has in a long time, so it's time to say goodbye to it. As this is the last platform using CONFIG_ARCH_USES_GETTIMEOFFSET, there are some follow-up patches to remove that as well.
