+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.

+U-Boot for Renesas SuperH 
+	Last update 08/10/2007 by Nobuhiro Iwamatsu
+
+================================================================================
+0. What's this?
+	This file contains status information for the port of U-Boot to the
+	Renesas SuperH series of CPUs.
+
+================================================================================
+1. Overview
+	SuperH has an original boot loader. However, source code is dirty, and 
+	maintenance is not done.
+	To improve sharing and the maintenance of the code, Nobuhiro Iwamatsu 
+	started the porting to u-boot in 2007. 
+
+================================================================================
+2. Supported CPUs
+
+	2.1. Renesas SH7750/SH7750R
+	2.2. Renesas SH7722
+
+================================================================================
+3. Supported Boards
+
+	3.1. Hitachi UL MS7750SE01/MS7750RSE01
+		Board specific code is in board/ms7750se
+		To use this board, type "make ms7750se_config".
+
+	3.2. Hitachi UL MS7722SE01
+		Board specific code is in board/ms7722se
+		To use this board, type "make ms7722se_config".
+
+	** README **
+		In SuperH, S-record and binary of made u-boot work on the memory.
+		When u-boot is written in the flash, it is necessary to change the 
+		address by using 'objcopy'.  
+		ex) shX-linux-objcopy -Ibinary -Osrec u-boot.bin u-boot.flash.srec
+	
+================================================================================
+4. Compiler
+	You can use the following of u-boot to compile. 
+		- SuperH Linux Open site
+			http://www.superh-linux.org/
+		- KPIT GNU tools
+			http://www.kpitgnutools.com/
+
+================================================================================
+5. Future
+	I plan to support the following CPUs and boards.
+		5.1. CPUs
+			- SH7710/SH7712 (SH3)
+			- SH7780(SH4)
+			- SH7785(SH4)
+		
+		5.2. Boards
+			- Many boards ;-)
