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

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!
