| 61fb15c5 | 20 | 1. base source code |
| 33ecdc2f | 21 | The code is based on sources from the Linux kernel |
| 53677ef1 | 22 | ( arch/sh/kernel/cf-enabler.c ). |

| 61fb15c5 | 24 | 2. How to use |
| 33ecdc2f NI |
25 | The options you have to specify in the config file are (with the |
| 26 | value for my board as an example): | |
| 27 | ||
| 28 | * CONFIG_MARUBUN_PCCARD | |
| 29 | If you want to use this device driver, should define CONFIG_MARUBUN_PCCARD. | |
| 53677ef1 | 30 | ex. #define CONFIG_MARUBUN_PCCARD |
| 61fb15c5 | 31 | |
| 33ecdc2f | 32 | * CONFIG_PCMCIA_SLOT_A |
| 53677ef1 | 33 | Most devices have only one slot. You should define CONFIG_PCMCIA_SLOT_A . |
| 33ecdc2f NI |
34 | ex. #define CONFIG_PCMCIA_SLOT_A 1 |
| 35 | ||
| 6d0f6bcf | 36 | * CONFIG_SYS_MARUBUN_MRSHPC |
| 1cc0a9f4 | 37 | This is MR-SHPC-01 PCMCIA controller base address. |
| 61fb15c5 | 38 | You should do the setting matched to your environment. |
| 6d0f6bcf | 39 | ex. #define CONFIG_SYS_MARUBUN_MRSHPC 0xb03fffe0 |
| 33ecdc2f NI |
40 | ( for MS7722SE01 environment ) |
| 41 | ||
| 6d0f6bcf | 42 | * CONFIG_SYS_MARUBUN_MW1 |
| 33ecdc2f | 43 | This is MR-SHPC-01 memory window base address. |
| 61fb15c5 | 44 | You should do the setting matched to your environment. |
| 6d0f6bcf | 45 | ex. #define CONFIG_SYS_MARUBUN_MW1 0xb0400000 |
| 33ecdc2f | 46 | ( for MS7722SE01 environment ) |
| 61fb15c5 | 47 | |
| 6d0f6bcf | 48 | * CONFIG_SYS_MARUBUN_MW1 |
| 33ecdc2f | 49 | This is MR-SHPC-01 attribute window base address. |
| 61fb15c5 | 50 | You should do the setting matched to your environment. |
| 6d0f6bcf | 51 | ex. #define CONFIG_SYS_MARUBUN_MW2 0xb0500000 |
| 33ecdc2f | 52 | ( for MS7722SE01 environment ) |

| 6d0f6bcf | 54 | * CONFIG_SYS_MARUBUN_MW1 |
| 33ecdc2f | 55 | This is MR-SHPC-01 I/O window base address. |
| 61fb15c5 | 56 | You should do the setting matched to your environment. |
| 6d0f6bcf | 57 | ex. #define CONFIG_SYS_MARUBUN_IO 0xb0600000 |
| 33ecdc2f NI |
58 | ( for MS7722SE01 environment ) |
