  * PMC551 PCI Mezzanine Ram Device

  * 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
- *       allows the mapping of system memory into an MTD device.
- *       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.

- *       * Modified driver to utilize a sliding aperture instead of

- *         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

- *       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.
