[U-Boot] [PATCH 0/5] mx5: USB host support for mx51evk and mx53loco

[Jana Rapava]

> This patches series provides USB host support for the mx51evk and

> and uses the header files of the ehci-fsl interface. The callback
> board_ehci_hcd_init() allows to do board-specific setup when USB is
> started.

Hi, I'm working on MX51 USB support based on some patches from Marek Vasut. 
It solves the problem in another way (uses structure-based offsets and generic
ULPI implementation I've written for this) and is probably more polished because
it's spent in the mailing list something like 2 months.
However, your patch supports both mx51 and mx53, so I think it would be nice
to find some way to get them together.
Last but not least, I'm sorry that I didn't respond to your first e-mail,
but I had to study for a test and hadn't time to look at your patch better.

Regards,
