[U-Boot] [PATCH 0/4] USB: Fix EHCI to work with data cache enabled

[puneets]

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
