[U-Boot] [PATCH] Add WinCE image load/boot cmd

[U-Boot] [PATCH] Add WinCE image load/boot cmd

[Ryan CHEN]

The patch is to add support functions which load and boot WinCE image.
It introduces one new CMD macro named 'CONFIG_CMD_WINCE'.
The source codes have tested on STLS board.

Sorry, this patch doesn't apply any more.

Can you please rebase and resubmit it? Thanks.

Best regards,

Do you have any plan to rebase it against current HEAD?

Hi,

	Could resend this code under either GPL or a clean, GPL-compatible BSD
	license.

	And BTW if needed put Opsycon AB in copy.
