[U-Boot] [PATCH RFC V1 00/18] Make mv_udc work for i.mx6

[Marek Vasut <marex@denx.de>]

Hi Troy,

> Hi Marek,

Can you please base the series on top of my series I posted a while ago [1] ? I 
feel bad about asking you to, but that series was out earlier and I'm planning 
to apply it for next MW.

btw review would be nice ;-)

Ugh, USB TTY is not compatible with the new code, right? I use either netconsole 
or the right way would be to port g_serial from Linux 2.6.37 .
