[PATCH] Add support for Prodrive P3M750 & P3M7448 (P3Mx) boards
This patch adds support for the Prodrive P3M750 (PPC750 & MV64460)
and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are
quite similar and share the same board directory "prodrive/p3mx"
and the same config file "p3mx.h".

This Gigabit Ethernet Controller driver API controls + *		1) Operations (i.e. port init, start, reset etc'). + *		2) Data flow (i.e. port send, receive etc'). + *		Each Gigabit Ethernet port is controlled via ETH_PORT_INFO + *		struct. + *		This struct includes user configuration information as well as + *		driver internal data needed for its operations. + * + *		Supported Features: + *		- This low level driver is OS independent. Allocating memory for + *		  the descriptor rings and buffers are not within the scope of + *		  this driver. + *		- The user is free from Rx/Tx queue managing. + *		- This low level driver introduce functionality API that enable + *		  the to operate Marvell's Gigabit Ethernet Controller in a + *		  convenient way. + *		- Simple Gigabit Ethernet port operation API. + *		- Simple Gigabit Ethernet port data flow API. + *		- Data flow and operation API support per queue functionality. + *		- Support cached descriptors for better performance. + *		- Enable access to all four DRAM banks and internal SRAM memory + *		  spaces. + *		- PHY access and control API. + *		- Port control register configuration API. + *		- Full control over Unicast and Multicast MAC configurations. + * + *		Operation flow: + * + *		Initialization phase + *		This phase complete the initialization of the ETH_PORT_INFO + *		struct. + *		User information regarding port configuration has to be set + *		prior to calling the port initialization routine. For example, + *		the user has to assign the port_phy_addr field which is board + *		depended parameter. + *		In this phase any port Tx/Rx activity is halted, MIB counters + *		are cleared, PHY address is set according to user parameter and + *		access to DRAM and internal SRAM memory spaces. + * + *		Driver ring initialization + *		Allocating memory for the descriptor rings and buffers is not + *		within the scope of this driver. Thus, the user is required to + *		allocate memory for the descriptors ring and buffers. Those + *		memory parameters are used by the Rx and Tx ring initialization + *		routines in order to curve the descriptor linked list in a form + *		of a ring. + *		Note: Pay special attention to alignment issues when using + *		cached descriptors/buffers. In this phase the driver store + *		information in the ETH_PORT_INFO struct regarding each queue + *		ring. + * + *		Driver start + *		This phase prepares the Ethernet port for Rx and Tx activity. + *		It uses the information stored in the ETH_PORT_INFO struct to + *		initialize the various port registers. + * + *		Data flow: + *		All packet references to/from the driver are done using PKT_INFO + *		struct. + *		This struct is a unified struct used with Rx and Tx operations. + *		This way the user is not required to be familiar with neither + *		Tx nor Rx descriptors structures. + *		The driver's descriptors rings are management by indexes. + *		Those indexes controls the ring resources and used to indicate + *		a SW resource error: + *		'current' + *		This index points to the current available resource for use. For + *		example in Rx process this index will point to the descriptor + *		that will be passed to the user upon calling the receive routine. + *		In Tx process, this index will point to the descriptor + *		that will be assigned with the user packet info and transmitted. + *		'used' + *		This index points to the descriptor that need to restore its + *		resources. For example in Rx process, using the Rx buffer return + *		API will attach the buffer returned in packet info to the + *		descriptor pointed by 'used'. In Tx process, using the Tx + *		descriptor return will merely return the user packet info with + *		the command status of  the transmitted buffer pointed by the + *		'used' index. Nevertheless, it is essential to use this routine + *		to update the 'used' index. + *		'first' + *		This index supports Tx Scatter-Gather. It points to the first + *		descriptor of a packet assembled of multiple buffers. For example + *		when in middle of Such packet we have a Tx resource error the + *		'curr' index get the value of 'first' to indicate that the ring + *		returned to its state before trying to transmit this packet. + * + *		Receive operation: + *		The eth_port_receive API set the packet information struct, + *		passed by the caller, with received information from the + *		'current' SDMA descriptor. + *		It is the user responsibility to return this resource back + *		to the Rx descriptor ring to enable the reuse of this source. + *		Return Rx resource is done using the eth_rx_return_buff API. + * + *		Transmit operation: + *		The eth_port_send API supports Scatter-Gather which enables to + *		send a packet spanned over multiple buffers. This means that + *		for each packet info structure given by the user and put into + *		the Tx descriptors ring, will be transmitted only if the 'LAST' + *		bit will be set in the packet info command status field. This + *		API also consider restriction regarding buffer alignments and + *		sizes. + *		The user must return a Tx resource after ensuring the buffer + *		has been transmitted to enable the Tx ring indexes to update. + * + *		BOARD LAYOUT + *		This device is on-board.  No jumper diagram is necessary. + * + *		EXTERNAL INTERFACE + * + *       Prior to calling the initialization routine eth_port_init() the user + *	 must set the following fields under ETH_PORT_INFO struct: + *       port_num             User Ethernet port number. + *       port_phy_addr		    User PHY address of Ethernet port. + *       port_mac_addr[6]	    User defined port MAC address. + *       port_config          User port configuration value. + *       port_config_extend    User port config extend value. + *       port_sdma_config      User port SDMA config value. + *       port_serial_control   User port serial control value. + *       *port_virt_to_phys ()  User function to cast virtual addr to CPU bus addr. + *       *port_private        User scratch pad for user specific data structures. + * + *       This driver introduce a set of default values: + *       PORT_CONFIG_VALUE           Default port configuration value + *       PORT_CONFIG_EXTEND_VALUE    Default port extend configuration value + *       PORT_SDMA_CONFIG_VALUE      Default sdma control value + *       PORT_SERIAL_CONTROL_VALUE   Default port serial control value + * + *		This driver data flow is done using the PKT_INFO struct which is + *		a unified struct for Rx and Tx operations: + *		byte_cnt	Tx/Rx descriptor buffer byte count. + *		l4i_chk		CPU provided TCP Checksum.
