Add platform device driver to populate the ax88796 platform data from

Yep, these have been a little annoying...
So I was wondering: why is this file included, as XSURF100 selects AX88796,
while ax88796.c includes lib8390.c anyway?
Apparently lib8390.c is included for register definitions (provided by
8390.h, and can easily be fixed), and for the __NS8390_init()
implementation, called below.
Mostly the latter.
+static void xs100_block_output(struct net_device *dev, int count,
+ const unsigned char *buf, const int start_page)
+{
[...]
+ while ((ei_inb(nic_base + EN0_ISR) & ENISR_RDC) == 0) {
+ if (jiffies - dma_start > 2 * HZ / 100) { /* 20ms */
+ netdev_warn(dev, "timeout waiting for Tx RDC.\n");
+ ei_local->reset_8390(dev);
+ ax_NS8390_init(dev, 1);
+ break;
+ }
+ }
+
+ ei_outb(ENISR_RDC, nic_base + EN0_ISR); /* Ack intr. */
+ ei_local->dmaing &= ~0x01;
+}
Can we get rid of the inclusion of lib8390.c, and the related warnings?
Perhaps ax88796.c can export its ax_NS8390_init(), iff the implementation
is identical? Or is there a better solution?
__NS8390_init() is declared static in lib8390.c, and we'd have to change
that. I don't think that will fly. Adding a wrapper to ax88796.c that
gets exported to the xsurf100 module might be an option - I'll see what
I can come up with.
Cheers,
Michael
Thanks!
