which is automatically included during kernel config, and add comments
to individual machine-dependant majors.* files to assign new MI majors
in MI file.
Range 0-191 is reserved for machine-specific assignments, range
192+ are MI assignments.

This code enables NetBSD to support for NEC VR4181 CPU and some
devices on L-Card+ board.
NEC VR4181
----------
NEC VR4181 is a embedded CPU which has MIPS processor core and
integrated I/O devices within a package. The basic architecture of
VR4181 is similar to other VR41xx family CPU. Some integrated devices
are compatible to another VR41xx series CPU and some are not.
VR4181 has integrated devices listed bellow:
- Two of 16550 compatible UART
- Compact Flash controller
- ISA bus controller
- Audio CODEC
- A/D converters
- LCD driver
- Touch panel controller
- General purpose I/O
L-Card+ Embedded CPU Board
--------------------------
L-Card+ is name card sized CPU board for embedded system. It is soled
by Laser5 (http://www.laser5.co.jp/) with Linux installed.
L-Card+ has following devices:
- 16Mbyte flash memory (Intel 28F128)
- 16Mbyte SDRAM
- CS8900A Ethernet controller and RJ45 port
- RS232C line driver and external connector
- Compact Flash socket
- A pair of Mezzanine connector for extension board
- Some on-board LEDs
Current Feature of This Code
----------------------------
Following devices are supported:
- UART (used for console)
- wi on Compact Flash socket
- cs (CS8900A)
- Flash memory (Intel 28F128 and Fujitsu MBM29LV160)
- Audio Coder (limited support)

This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
