[U-Boot-Users] EEPROM content and multiple NIC

[Daniel Ann <ktdann@gmail.com>]

I'm very curious about this output I'm getting,

=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
        00  14  100b  0020  0200  ff
In:    serial
Out:   serial
Err:   serial
Net:   natsemi: EEPROM contents:
 d008 0001 0001 0001 0001 0001 0001 0001 0001 0001 1841 0001
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

As far as I know, NS83815 manual claims that d008 is a default value
for vendor ID. but pci_ids thinks 100b is National semiconductor's
vendor ID. Does anyone know why the difference ?

Also, board Im using has EEPROM to configure the NIC during reset. And
it contains 100b (shown on first line of output), however, print out
of EEPROM from natsemi.c shows d008 as written in the NS83815 manual.

I'm reading the natsemi.c but I just cant see why it would read some
other value. This is a cut out of the source from natsemi.c

-------------cut--------------
        printf("natsemi: EEPROM contents:\n");
        for (i = 0; i <= EEPROM_SIZE; i++) {
            short eedata = read_eeprom(dev, EECtrl, i);
            printf(" %04hx", eedata);
        }
----------end cut-----------

EEPROM_SIZE = 12 <- correct
EECtrl = 0x08 <- correct too

Another question is, I have several NIC. When I do tftpboot from first
card, works. It prints out,
Using dp83815#0 device

Next, when I remove the cable from first card, insert it to second
card, run the same command, it works, and prints out,
Using dp83815#0 device

I'm pretty sure it should print out "Using dp83815#1 device". Possibly
failed attempt from using dp83815#0 device. What do you all think?

I havent looked@it deeper enuf, but if I can get some shared
thoughts it would help me out great deal.
