I'm experiencing an issue when loading a generic distro initramfs
on trimslice-pro (with ssd using ehci) with the default value of
65535 for USB_MAX_XFER_BLK
EHCI timed out on TD - token=0x80008d80
As adviced by Marek on IRC, using a lower value for
USB_MAX_XFER_BLK allows to load the file
Tested values on tegra20-trimslice:
4095 ok
32767 ok
32768 timeout
36864 timeout
40960 timeout
49150 timeout
Tested on current u-boot master
