It is an on-going process to convert existing drivers to driver model. 
The spi-flash has driver model now. How do you think it is unlikely that 
cfi-flash should be converted to driver-model?

It is not just base address. There is device binding with compatible 
ids. There will be resources allocation, too. Please don't limit your 
imagination by my poor coding skill.

There are three good things to u-boot in recent years, the Kconfig, 
device tree control and driver model. Together, they provide more 
flexibility to processors on FPGA, like nios2. Here almost everything is 
programmable, and it is difficult to hard code driver setup in the old way.

Huge thanks to all the contributors. Thank you too, Bin.

Best regards,
Thomas
