+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!
