Avoid unlimited while loop by adding a timeout. The timeout is
calculated based on a minimal throughput of 256 KB/s.
The timeout is set at least to 2 seconds.

All external devices share the addresses, data and control signals with the
controller. Each external device is accessed by means of a unique Chip
Select. The FMC2 performs only one access at a time to an external device.

The chip select defined in the device tree could only be 0 or 1.

That looks like a hack, it would collide with the actual FMC2 driver

Thanks
Hi Marek,
I have already prepared a set of patches to add the full FMC2 support in
U-Boot based on kernel drivers. I am currently waiting for the bindings
and the drivers being reviewed on kernel side.
Regards,
Christophe Kerello.
