[U-Boot] framework for serial flash

Hello

We have a special "Serial flash controller" which was put into the standard flash framework of uboot (common/cmd_flash.c). Commands like 'cp', 'erase' could be used for operation over serial flash.

Now we have to use parallel flash (CFI), hence it is required to handle "Serial flash controller" in another manner as both are exporting 'write_buff' leading to a conflict.

Since we felt "Serial flash controller" resembles SPI flash framework, and hence decided to move it there. Problem is that this "Serial flash controller" is also not fitting in SPI framework because of its nature.

How to handle such situations, is there any other framework or we need to introduce our own commands? We are using "u-boot-2009.08".

Thanks Ashish
