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 ;-)
