* Description:
|
|
|
- * This driver is intended to support the PMC551 PCI Ram device
|
|
|
- * from Ramix Inc. The PMC551 is a PMC Mezzanine module for
|
|
|
- * cPCI embedded systems. The device contains a single SROM
|
|
|
- * that initially programs the V370PDC chipset onboard the
|
|
|
- * device, and various banks of DRAM/SDRAM onboard. This driver
|
|
|
- * implements this PCI Ram device as an MTD (Memory Technology
|
|
|
- * Device) so that it can be used to hold a file system, or for
|
|
|
- * added swap space in embedded systems. Since the memory on
|
|
|
- * this board isn't as fast as main memory we do not try to hook
|
|
|
- * it into main memory as that would simply reduce performance
|
|
|
- * on the system. Using it as a block device allows us to use
|
|
|
- * it as high speed swap or for a high speed disk device of some
|
|
|
- * sort. Which becomes very useful on diskless systems in the
|
|
|
- * embedded market I might add.

|
* Notes:
|
|
|
- * Due to what I assume is more buggy SROM, the 64M PMC551 I
|
|
|
- * have available claims that all 4 of it's DRAM banks have 64M
|
|
|
- * of ram configured (making a grand total of 256M onboard).
|
|
|
- * This is slightly annoying since the BAR0 size reflects the
|
|
|
- * aperture size, not the dram size, and the V370PDC supplies no
|
|
|
- * other method for memory size discovery. This problem is
|
|
|
- * mostly only relevant when compiled as a module, as the
|
|
|
- * unloading of the module with an aperture size smaller then
|
|
|
- * the ram will cause the driver to detect the onboard memory
|
|
|
- * size to be equal to the aperture size when the module is
|
|
|
- * reloaded. Soooo, to help, the module supports an msize
|
|
|
- * option to allow the specification of the onboard memory, and
|
|
|
- * an asize option, to allow the specification of the aperture
|
|
|
- * size. The aperture must be equal to or less then the memory
|
|
|
- * size, the driver will correct this if you screw it up. This
|
|
|
- * problem is not relevant for compiled in drivers as compiled
|
|
|
- * in drivers only init once.

- * Most of the MTD code for this driver was originally written

- * for the slram.o module in the MTD drivers package which

|

|
|
|
- * Since the PMC551 memory module is accessed in the same
|
|
|
- * fashion as system memory, the slram.c code became a very nice
|
|
|
- * fit to the needs of this driver. All we added was PCI
|
|
|
- * detection/initialization to the driver and automatically figure
|
|
|
- * out the size via the PCI detection.o, later changes by Corey
|
|
|
- * Minyard set up the card to utilize a 1M sliding apature.

|
- * be very wasteful.
|
|
|
- * * Located a bug in the SROM's initialization sequence that

- * made the memory unusable, added a fix to code to touch up
|
|

- * the DRAM some.

|

|
* Bugs/FIXME's:
|
|
|
- * * MUST fix the init function to not spin on a register
|
|
|
- * waiting for it to set .. this does not safely handle busted
|
|
|
- * devices that never reset the register correctly which will
|
|
|
- * cause the system to hang w/ a reboot being the only chance at
|
|
|
- * recover. [sort of fixed, could be better]
|
|
|
- * * Add I2C handling of the SROM so we can read the SROM's information
|
|
|
- * about the aperture size. This should always accurately reflect the
|
|
|
- * onboard memory size.
|
|
|
- * * Comb the init routine. It's still a bit cludgy on a few things.
