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. Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>

0. What's this?
|
|
This driver supports MARUBUN MR-SHPC-01.

|
|
(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.
