[ECOS] smsc91c111 driver for redboot

[ECOS] smsc91c111 driver for redboot

[tejas pawaskar]

I am using smsc91c111 ethernet driver as part of my
redboot bootloader.

The base address is 0x10000000.

I get the following error 
"smsc_lan91cxx_init: No 91Cxx signature found"

From the driver source code, it seems that the driver
was not able to probe the signature in BS register.

Is this means that my smsc91c111 chip itself is not
getting selected?

What's the basic configuration settings to get the
chip  going?

Regards
Tejas Pawaskar

You haven't provided enough information for us to help you.
What platform/architecture are you using?

I am using Intel's Xscale PXA270 processor, Redboot as
my bootloader.

The iobase address is 0x10000000.
I wrote a small for loop for reading 16MB data from
0x10000000, so that it would cover the signature
register of smsc91c111.
For the entire 16MB it read 3 for even address and 0
for odd address.

In the datasheet of smsc91c111, it is mentioned that
address is 16-bit and data is 32-bit. I didnt get the
meaning of it.

Thanks with kind Regards,
