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

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

Puneet, can you please test this stuff? It should fix your cache misalignment issues. Mine are now gone and USB works with caches on too.

I'd like to queue this for -next.

Best regards,
Marek Vasut
