Xilinx OPB EMC Linux 2.6 Driver

Xilinx OPB EMC Linux 2.6 Driver

[Mohammad Sadegh Sadri]

Hi All,

I'm going to use intel strata flash chip on ml403 for bringing up my 2.6 ke=
rnel. ( I do not want to use Sys ACE any more )

At the first step I have some simple questions

2.6 Kernel provides a wide range of support for flash devices, from CFI to =
many other types, I can enable any of them I want.=20

But I think that some thing is missing here, There should be a driver to en=
able Extended Memory Controller (OPB EMC) module which is mainly connected =
to the strata flash chip. Is this true? Or the current drivers in the kerne=
l are enough?=20

May be I should enable support for CFI and then I choose CFI in physical me=
mory option?

Thanks.

The EMC core does not require any drivers.  It transparently maps 
external devices onto the OPB bus.

Yes
