-   Kernel module for the dp83820 flash write utility. This code was written
-   by Dave Ashley for NXTV, Inc.
-   Copyright 2004 by NXTV, Inc.
-   Written 20040219 by Dave Ashley.
-
-   This code is released under the terms of the GPL. No warranty.
-
-   THEORY: The dp83820 bootrom interface is flawed in that you can't
-   read or write a single byte at a time, and this is required in order
-   to write to flash devices like the AT29C512. So the workaround is
-   to use the chips ability to map into memory the bootrom, then the cpu
-   can directly do byte accesses.
-
-   The problem is that a "feature" of the dp83820 is that when you map
-   in the bootrom, you conveniently lose access to the PCI registers.
-   So we need to do this in kernel space and wrap every access to the
-   bootrom within interrupt_disable/restore, in case a network interrupt
-   were to come in.
-
-   This kernel module is very simple, it just creates a proc file
-   /proc/dp83820
-   If you write 3 bytes to this file you are doing a write to the flashrom:
-
-Byte 1   2    3
-   ALOW AHIGH DATA
-
-   If you write 2 bytes to this file you are doing a read from the flashrom:
-Byte 1   2
-   ALOW AHIGH
-   Then the next read from the file will return a single byte of what
-   was at that location.
-
-   You only get one shot at accessing the proc file, you need to then
-   close/open if you want to do another access. This could probably be
-   cleaned up pretty easily so more accesses can be done without having
-   to close/open the file.
