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 * 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 ) 3. Other * Check Compact Flash only. * Maybe, NE2000 compatible NIC is sure to move. Copyright (c) 2007 Nobuhiro Iwamatsu
