| (Sorry Japanese only.) |
| |
| This chip is used with SuperH well, and adopted by the |
| reference board. |
| ex. * MS7750SE01 |
| * MS7722SE01 |
| * other |

| 1. base source code |
| The code is based on sources from the Linux kernel |
| ( arch/sh/kernel/cf-enabler.c ). |

| 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 controler 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 ) |
