This driver supports NE2000 compatible cards (those based on DP8390,
|
||
|
|
DP83902 and similar). It can be used with PCMCIA/CF cards provided
|
||
|
|
that the CCR is correctly initialized.
|
||
|
|
|
||
|
|
The code is based on sources from the Linux kernel (pcnet_cs.c,
|
||
|
|
8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2
|
||
|
|
wonderful world are GPL, so this is, of course, GPL.
|
||
|
|
|
||
|
|
I developed and tested this driver on a custom PXA255 based system and
|
||
|
|
with a billionton CF network card connected to the PCMCIA interface of
|
||
|
|
the micro (have a look at README.PXA_CF for the support of this port).
|
||
|
|
|
||
|
|
The options you have to specify in the config file are (with the
|
||
|
|
value for my board as an example):
|
||
|
|
|
||
|
|
#define CONFIG_DRIVER_NE2000
|
||
|
|
|
||
|
|
- Enables the driver
|
||
|
|
|
||
|
|
#define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300)
|
||
|
|
|
||
|
|
- Address where the board is mapped
|
||
|
|
|
||
|
|
#define CONFIG_DRIVER_NE2000_CCR (0x28000000+0x3f8)
|
||
|
|
|
||
|
|
- Address of the CCR (card configuration register). It could be found
|
||
|
|
by enabling DEBUG in cmd_pcmcia.c. If this is not defined nothing is
|
||
|
|
done as far as PCMCIA support is concerned.
|
||
|
|
|
||
|
|
#define CONFIG_DRIVER_NE2000_VAL (0x20)
|
||
|
|
|
||
|
|
- The value to be written in the CCR. It selects among different I/O
|
||
|
|
spaces that could be used by the card.
|
||
|
|
|
||
|
|
|
||
|
|
Enjoy!
