[U-Boot] USB support in U-boot for MX23EVK board

[U-Boot] USB support in U-boot for MX23EVK board

[Shilpa Budhihal]

Hi,
     I'm struggling to find USB support in U-Boot for MX23EVK board. I'm building u-boot source using LTIB(L2.6.31_10.05.02_ER_source.tar downloaded from internet). I'm able to find USB driver(i.e., ehci-hcd.c file) in U-Boot source 2009.08. But usb_init function call is not made in board_init function in the corresponding board specific file (evk23_evk.c). Could you help me finding what could be done for enabling USB support in u-boot to support for ARM based mx23evk board.


Thanks and Regards,
Shilpa

Sorry, but LTIB is a Freescale provided out-of-tree port.  We can only
support mainline U-Boot here.  Please contact Freescale support for
problems with the Freescale code.

So far, Freescale did not bother to push their i.MX23 support
upstream (and nobody else did this either).  So we cannot help you.

Please contact Freescale support with questions to Freescale's LTIB
code.

Please use ELDK, 5.1 is preffered as that's the latest version. LTIB is ancient 
crap.

Oh come on ... git clone git://git.denx.de/u-boot-imx.git

Yes, use the above, for the reference, you can use board/denx/m28evk

...but only as a starting point for a new port. i.MX23 is similar to
i.MX28 in many areas, but sufficiently different to cause enough
problems to a newbie.

One possible reason that things aren't going  according  to  plan  is
that there never was a plan in the first place.

You're definitelly right, but such a newbie has an U-Boot mailing list where he 
can ask if he's not sure how to go about various things. :)

Cheers!
