Hi,<br>
I am going through the uboot drivers code for smc91111 ethernet controller in uboot.<br>
<br>
My Objective is to know how boot loader configures the ethernet controller.<br>
<br>
This is for the first time i am going thru a boot loader code.<br>
<br>
I have some doubts:<br>
<br>
How does a boot
loader know which device is connected. say i have connected the smc
91111 ethernet <br>
controller - how does it know it is smc91111
controller.<br>
<br>
I think as soon as it
detects the smc91111 controller is connected. it must configure
that - i think the <br>
code in drivers/smc91111.c must be executed.<br>
<br>
What will happen if there are 2 ethernet controllers in the board. how
u-boot responds to this.<br>
<br>
However, i am not following the code given in smc91111.c i really dont
know what it is doing ?.<br>
<br>
i have the
data sheets with me and going thru it. i must admit i am totally
confused.<br>
<br>
Does
anybody know what constitues configuring a ethernet controller and
what the code does ?.<br>
<br>
i would
request you to kindly let me the flow in u-boot. from startup to
configuring ind. devices.<br>
<br>
<br>
Any description is available in this matter will be very useful. <br>
<br>
<br>
Any pointers in this matter is highly appreciated.<br>
<br>
<br>
Thanks,<br>
<br>
<br>
