[LinuxBIOS] Enabling USB 2.0

[Anil B G]

Hi,
  I am trying to enable USB on a board similar to Tyan s2892 (CK804)
chipset?
Is there anything that else that needs to be done separately other than
setting the irqs et al correctly? Specifically do we need to write some sort
of a driver to enable the USB host controller.

Thanks
Anil

Assuming you don't hope to boot from USB, all you really should need is 
to setup the IRQ map, AFAIK.  Then the Linux kernel will detect it and 
be able to attach the appropriate driver.

Thanks. I plan to boot from SATA and not from USB.  Do any other boards
supported by LinuxBIOS (whose source is available in the source tree)
bringup USB that I could use as a reference?

Probably most boards enable USB.  The irq_tables.c for each mainboard 
has the IRQ map in it.  I believe this file can be generated 
automatically if you boot using the stock BIOS and run the generator 
tool.  I am working mostly on a system without a standard BIOS and am 
coddling this file together manually.  Either way, take a look at it to 
get an idea of what it does.  There have also been a fair number of 
posts related to constructing this file, so search the archives too.
