      1 This driver supports NE2000 compatible cards (those based on DP8390,
      2 DP83902 and similar). It can be used with PCMCIA/CF cards provided
      3 that the CCR is correctly initialized.
      4 
      5 The code is based on sources from the Linux kernel (pcnet_cs.c,
      6 8390.h) and eCOS(if_dp83902a.c, if_dp83902a.h). Both of these 2
      7 wonderful world are GPL, so this is, of course, GPL.

      9 I developed and tested this driver on a custom PXA255 based system and
     10 with a billionton CF network card connected to the PCMCIA interface of
     11 the micro (have a look at README.PXA_CF for the support of this port).
     12 
     13 The options you have to specify in the config file are (with the
     14 value for my board as an example):
     15 
     16 #define CONFIG_DRIVER_NE2000
     17 
     18 - Enables the driver
     19 
     20 #define CONFIG_DRIVER_NE2000_BASE (0x20000000+0x300)
     21 
     22 - Address where the board is mapped
     23 
     24 #define CONFIG_DRIVER_NE2000_CCR (0x28000000+0x3f8)
     25 
     26 - Address of the CCR (card configuration register). It could be found
     27 by enabling DEBUG in cmd_pcmcia.c. If this is not defined nothing is
     28 done as far as PCMCIA support is concerned.
     29 
     30 #define CONFIG_DRIVER_NE2000_VAL (0x20)
     31 
     32 - The value to be written in the CCR. It selects among different I/O
     33 spaces that could be used by the card.
