MIPS: PCMCIA: new socket driver for Au1000 demoboards.
New PCMCIA socket driver for all Db/Pb1xxx boards (except Pb1000), which replaces au1000_db1x00.c and (most of) au1000_pb1x00.c. Notable improvements: - supports Db1000, DB/PB1100/1500/1550/1200. - support for carddetect and statuschange IRQs. - pcmcia socket mem/io/attr areas and irqs passed through platform resource information. - doesn't freeze system during card insertion/ejection like the one it replaces. - boardtype is automatically detected using BCSR ID register. Run-tested on the DB1200. Cc: Linux-PCMCIA <linux-pcmcia@lists.infradead.org> Signed-off-by: Manuel Lauss <manuel.lauss@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
