===============================================
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)

- editing of the extended partition list
- user friendly default start/size for new partitions
- partition start/size input in sectors, cylinders or MB
- bootsel menu names configured with paritition bounds
- partition update loop asks used which partition to change
(instead of asking about each partition in turn).
- detection (and erroring) of overlapped partitions.
- automatic installation of correct mbr_xxx code (after prompting user)
the insides of struct _dirdesc. Also make the existence of struct
_dirdesc visible to POSIX applications since this is less ugly than
pretending that DIR is a void *.
for the IOHIDSystem driver in Darwin. IOHIDSystem provides access
to user interface devices.
Communication between userspace and kernel is done through a shared
memory page. Our plan is to have a kernel thread waiting on wscons
events (for now it just does nothing), and have it feeding the
shared page.
