| 11 | This provides a MTD device driver for the Ramix PMC551 RAM PCI card |
| 12 | from Ramix Inc. <http://www.ramix.com/products/memory/pmc551.html>. |
| 13 | These devices come in memory configurations from 32M - 1G. If you |
| 14 | have one, you probably want to enable this. |
| 15 | |
| 16 | If this driver is compiled as a module you get the ability to select |
| 17 | the size of the aperture window pointing into the devices memory. |
| 18 | What this means is that if you have a 1G card, normally the kernel |
| 19 | will use a 1G memory map as its view of the device. As a module, |
| 20 | you can select a 1M window into the memory and the driver will |
| 21 | "slide" the window around the PMC551's memory. This was |
| 22 | particularly useful on the 2.2 kernels on PPC architectures as there |
| 23 | was limited kernel space to deal with. |
