/*
* Ethernut 5 general board support
*
* Ethernut is an open source hardware and software project for
* embedded Ethernet devices. Hardware layouts and CAD files are
* freely available under BSD-like license.
*
* Ethernut 5 is the first member of the Ethernut board family
* with U-Boot and Linux support. This implementation is based
* on the original work done by Ole Reinhardt, but heavily modified
* to support additional features and the latest board revision 5.0F.
*
* Main board components are by default:
*
* Atmel AT91SAM9XE512 CPU with 512 kBytes NOR Flash
* 2 x 64 MBytes Micron MT48LC32M16A2P SDRAM
* 512 MBytes Micron MT29F4G08ABADA NAND Flash
* 4 MBytes Atmel AT45DB321D DataFlash
* SMSC LAN8710 Ethernet PHY
* Atmel ATmega168 MCU used for power management
* Linear Technology LTC4411 PoE controller
*
* U-Boot relevant board interfaces are:
*
* 100 Mbit Ethernet with IEEE 802.3af PoE
* RS-232 serial port
* USB host and device
* MMC/SD-Card slot
* Expansion port with I2C, SPI and more...
*
* Typically the U-Boot image is loaded from serial DataFlash into
* SDRAM by the samboot boot loader, which is located in internal
* NOR Flash and provides all essential initializations like CPU
* and peripheral clocks and, of course, the SDRAM configuration.
*
* For testing purposes it is also possibly to directly transfer
* the image into SDRAM via JTAG. A tested configuration exists
* for the Turtelizer 2 hardware dongle and the OpenOCD software.
* In this case the latter will do the basic hardware configuration
* via its reset-init script.
*
* For additional information visit the project home page at
* http://www.ethernut.de/

/*
* Ethernut 5 power management support
*
* This board may be supplied via USB, IEEE 802.3af PoE or an
* auxiliary DC input. An on-board ATmega168 microcontroller,
* the so called power management controller or PMC, is used
* to select the supply source and to switch on and off certain
* energy consuming board components. This allows to reduce the
* total stand-by consumption to less than 70mW.
*
* The main CPU communicates with the PMC via I2C. When
* CONFIG_CMD_BSP is defined in the board configuration file,
* then the board specific command 'pwrman' becomes available,
* which allows to manually deal with the PMC.
*
* Two distinct registers are provided by the PMC for enabling
* and disabling specific features. This avoids the often seen
* read-modify-write cycle or shadow register requirement.
* Additional registers are available to query the board
* status and temperature, the auxiliary voltage and to control
* the green user LED that is integrated in the reset switch.
*
* Note, that the AVR firmware of the PMC is released under BSDL.
*
* For additional information visit the project home page at
* http://www.ethernut.de/
