sh: Add marubun's pcmcia driver
Marubun pcmcia is a chip for PCMCIA used with SuperH.
Of course, this can be used even by other architectures.
When use this driver, came to be able to use CompactFlash
and Ethernet.

+U-Boot MARUBUN MR-SHPC-01 PCMCIA controller driver
+ Last update 21/11/2007 by Nobuhiro Iwamatsu
+
+========================================================================================
+
+0. What's this?
+ This driver supports MARUBUN MR-SHPC-01.
+ url: http://www.marubun.co.jp/product/semicon/devices/qgc18e0000002n2z.html
+ (Sorry Japanese only.)
+
+ This chip is used with SuperH well, and adopted by the
+ reference board.
+ ex. * MS7750SE01
+ * MS7722SE01
+ * other
+
+ This chip doesn't support CardBus.
+
+1. base source code
+ The code is based on sources from the Linux kernel
+ ( arch/sh/kernel/cf-enabler.c ).
+
+2. How to use
+ The options you have to specify in the config file are (with the
+ value for my board as an example):
+
+ * CONFIG_MARUBUN_PCCARD
+ If you want to use this device driver, should define CONFIG_MARUBUN_PCCARD.
+ ex. #define CONFIG_MARUBUN_PCCARD
+
+ * CONFIG_PCMCIA_SLOT_A
+ Most devices have only one slot. You should define CONFIG_PCMCIA_SLOT_A .
+ ex. #define CONFIG_PCMCIA_SLOT_A 1
+
+ * CFG_MARUBUN_MRSHPC
+ This is MR-SHPC-01 PCMCIA controler base address.
+ You should do the setting matched to your environment.
+ ex. #define CFG_MARUBUN_MRSHPC 0xb03fffe0
+ ( for MS7722SE01 environment )
+
+ * CFG_MARUBUN_MW1
+ This is MR-SHPC-01 memory window base address.
+ You should do the setting matched to your environment.
+ ex. #define CFG_MARUBUN_MW1 0xb0400000
+ ( for MS7722SE01 environment )
+
+ * CFG_MARUBUN_MW1
+ This is MR-SHPC-01 attribute window base address.
+ You should do the setting matched to your environment.
+ ex. #define CFG_MARUBUN_MW2 0xb0500000
+ ( for MS7722SE01 environment )
+
+ * CFG_MARUBUN_MW1
+ This is MR-SHPC-01 I/O window base address.
+ You should do the setting matched to your environment.
+ ex. #define CFG_MARUBUN_IO 0xb0600000
+ ( for MS7722SE01 environment )
+
+3. Other
+ * Check Compact Flash only.
+ * Maybe, NE2000 compatible NIC is sure to move.
