This provides a MTD device driver for the Ramix PMC551 RAM PCI card
|
||
|
|
from Ramix Inc. <http://www.ramix.com/products/memory/pmc551.html>.
|
||
|
|
These devices come in memory configurations from 32M - 1G. If you
|
||
|
|
have one, you probably want to enable this.
|
||
|
|
|
||
|
|
If this driver is compiled as a module you get the ability to select
|
||
|
|
the size of the aperture window pointing into the devices memory.
|
||
|
|
What this means is that if you have a 1G card, normally the kernel
|
||
|
|
will use a 1G memory map as its view of the device. As a module,
|
||
|
|
you can select a 1M window into the memory and the driver will
|
||
|
|
"slide" the window around the PMC551's memory. This was
|
||
|
|
particularly useful on the 2.2 kernels on PPC architectures as there
|
||
|
|
was limited kernel space to deal with.

is only really useful if you are developing on this driver or
