Subject: [U-Boot] [PATCH 0/4] USB: Fix EHCI to work with data cache enabled
Date: Mon, 9 Apr 2012 13:03:06 +0530	[thread overview]
Message-ID: <4F8290B2.3@nvidia.com> (raw)
In-Reply-To: <201204090512.33178.marex@denx.de>

Dear Marek,
After applying these 4 patches I don't see any alignment spew and it 
detects the
mass storage device perfectly though I see a warning "EHCI timed out on 
TD - token=0x80008c80"
consistently in each "usb reset".

Thanx & Regards,
Puneet
