Dear Marco,

Such devices like my EPSON controller are a not kernel specificly. Will it be used like a normal device with a device driver ???
This depends on the implementation. Often you will find some device driver provided by the chip manufacturer (or some other third parties). And often this driver will provide a standard framebuffer interface.
My kernel config has no option for a EPSON graphic controller, i think.
It might have one after adding the driver to your kernel source tree :-)
Where do the embedded Linux store the parameters which was given by u-boot?
Parameters are passed in registers plus some data structure in RAM. How and where Linux stores this information depends on a couple of things, like processor architecture and kernel version.
Why do you ask?
[Maybe we should move this discussion into a Linux group?]
Best regards,
Wolfgang Denk
