10 | (Sorry Japanese only.) | |
11 | ||
12 | This chip is used with SuperH well, and adopted by the | |
13 | reference board. | |
14 | ex. * MS7750SE01 | |
15 | * MS7722SE01 | |
16 | * other | |
17 | ||
18 | This chip doesn't support CardBus. | |
19 | ||
20 | 1. base source code | |
21 | The code is based on sources from the Linux kernel | |
22 | ( arch/sh/kernel/cf-enabler.c ). | |
23 | ||
24 | 2. How to use | |
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. | |
30 | ex. #define CONFIG_MARUBUN_PCCARD | |
31 | ||
32 | * CONFIG_PCMCIA_SLOT_A | |
33 | Most devices have only one slot. You should define CONFIG_PCMCIA_SLOT_A . | |
34 | ex. #define CONFIG_PCMCIA_SLOT_A 1 | |
35 | ||
36 | * CONFIG_SYS_MARUBUN_MRSHPC | |
37 | This is MR-SHPC-01 PCMCIA controler base address. | |
38 | You should do the setting matched to your environment. | |
39 | ex. #define CONFIG_SYS_MARUBUN_MRSHPC 0xb03fffe0 | |
40 | ( for MS7722SE01 environment ) | |
41 | ||
42 | * CONFIG_SYS_MARUBUN_MW1 | |
43 | This is MR-SHPC-01 memory window base address. | |
44 | You should do the setting matched to your environment. | |
45 | ex. #define CONFIG_SYS_MARUBUN_MW1 0xb0400000 | |
46 | ( for MS7722SE01 environment ) | |
47 | ||
48 | * CONFIG_SYS_MARUBUN_MW1 | |
49 | This is MR-SHPC-01 attribute window base address. | |
50 | You should do the setting matched to your environment. | |
51 | ex. #define CONFIG_SYS_MARUBUN_MW2 0xb0500000 | |
52 | ( for MS7722SE01 environment ) | |
53 | ||
54 | * CONFIG_SYS_MARUBUN_MW1 | |
55 | This is MR-SHPC-01 I/O window base address. | |
56 | You should do the setting matched to your environment. | |
57 | ex. #define CONFIG_SYS_MARUBUN_IO 0xb0600000 | |
58 | ( for MS7722SE01 environment ) | |
59 | ||
60 | 3. Other | |
61 | * Check Compact Flash only. | |
62 | * Maybe, NE2000 compatible NIC is sure to move. | |
