[U-Boot] U-boot with USB storage support for WonderMedia WM8505

[EvilSibling <chris.p.barnes@gmail.com>]

Hi everyone,

I'm new to this forum so im not sure if im in the right place. I tried
searching for a solution but didnt find a solution.

I have a 7" Netbook based on the WonderMedia WM8505 processor. Based on all
the other forums ive read out there it looks like the hardware is very
similar to a lot of the other 7" netbooks and 7" tablets out there.

The netbook came preloaded with Windows CE 6.

The problem ive got is I inherited the netbook broken. It appeares to be
broken after a failed Android install.

The serial console on the mainboard shows wload and u-boot starts fine.

The problem looks to me like the Android installer has replaced the u-boot
which was preloaded on the netbook.

I looked through the environment variables in u-boot via the serial console
and i saw an old bootcmd variable which referred to USB commands - usbinit,
fatload usb 0:1, etc to boot the system however the uboot which is running
on the netbook now has no such commands available.

The new u-boot seems to support NAND, IDE, and MMC storage because commands
for those storage devices are available, however the NAND and IDE commands
both report no devices/controllers detected.

Ive inspected the mainboard in this netbook and its onboard storage is a USB
flash disk - that is its a 2gig NAND flash presented to the system via USB.

So my question is this.

Can anyone suggest where I could download a u-boot which has usb storage
support which might run on this netbook?

OR

Can anyone give me any suggestions how I could make a compatible u-boot from
source.

Ive downloaded the source from the DENX website and had a look but the
problem ive got is the 'make' program expects me to specify which system
board to build the u-boot binary for but none of the board names in the
u-boot source seem to resemble anything like the board in this netbook so I
dont know which board configuration to use.

These netbooks are so common and all have such similar hardware surely one
of the board configurations would match well but which one?
