BAST is the one machine that theoretically supports unmodified ISA drivers for hardware on its PC/104 connector, using a custom version of the inb()/outb() and inw()/outw() macros. This is incompatible with the generic version used in asm/io.h, and can't easily be used in a multiplatform kernel. Removing the special case for 16-bit I/O port access on BAST gets us closer to multiplatform, at the expense of any PC/104 users with 16-bit cards having to either use an older kernel or modify their ISA drivers to manually ioremap() the area and use readw()/write() in place of inw()/outw(). Either way is probably ok, given that there is a recurring discussion about dropping s3c24xx altogether, and many traditional ISA drivers are already gone. Machines other than BAST already have no support for ISA drivers, though a couple of them do map one of the external chip-selects into the ISA port range, using the same address for 8-bit and 16-bit I/O. It is unlikely that anything actually uses this mapping, but it's also easy to keep this working by mapping it to the normal platform-independent PCI I/O base that is otherwise unused on s3c24xx. The mach/map-base.h file is no longer referenced in global headers and can be moved into the platform directory.
