  	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

      * CONFIG_SYS_MARUBUN_MRSHPC

  	This is MR-SHPC-01 PCMCIA controller base address.

  	You should do the setting matched to your environment.

  	ex.  #define CONFIG_SYS_MARUBUN_MRSHPC 0xb03fffe0

  	     ( for MS7722SE01 environment )

      * CONFIG_SYS_MARUBUN_MW1

  	This is MR-SHPC-01 memory window base address.

  	You should do the setting matched to your environment.

  	ex. #define CONFIG_SYS_MARUBUN_MW1 0xb0400000

  	     ( for MS7722SE01 environment )

      * CONFIG_SYS_MARUBUN_MW1

  	This is MR-SHPC-01 attribute window base address.

  	You should do the setting matched to your environment.

  	ex. #define CONFIG_SYS_MARUBUN_MW2 0xb0500000

  	     ( for MS7722SE01 environment )

      * CONFIG_SYS_MARUBUN_MW1

  	This is MR-SHPC-01 I/O window base address.

  	You should do the setting matched to your environment.

  	ex. #define CONFIG_SYS_MARUBUN_IO  0xb0600000

  	     ( for MS7722SE01 environment )

      * Check Compact Flash only.
      * Maybe, NE2000 compatible NIC is sure to move.
