These boards have been orphaned for a while and old enough.

-This directory contains board specific code for a generic MPC860T based
-embedded computer, called 'GEN860T'.  The design is generic in the sense that
-common, readily available components are used and that the architecture of the
-system is relatively straightforward:
-
-	One eight bit wide boot (FLASH) memory
-	32 bit main memory using SDRAM
-	DOC 2000+
-	Ethernet PHY
-	Some I2C peripheral devices: Atmel AT24C256 EEPROM, Maxim DS1337 RTC.
-	Some other miscellaneous peripherals
-
-NOTE: There are references to a XIlinx FPGA and Mil-Std 1553 databus in this
-port.  I guess the computer is not as generic as I first said 8)  However,
-these extras can be safely ignored.
-
-Given the GEN860T files, it should be pretty easy to reverse engineer the
-hardware configuration, if that's useful to you.  Hopefully, this code will
-be useful to someone as a basis for a port to a new system or as a head start
-on a custom design.  If you end up using any of this, I would appreciate
-hearing from you, especially if you discover bugs or find ways to improve the
-quality of this U-Boot port.
-
-Here are the salient features of the system:
-Clock						:	33.3 Mhz oscillator
-Processor core frequency	:	66.6 Mhz  if in 1:2:1 mode; can also run 1:1
-Bus frequency				:	33.3 Mhz
-
-Main memory:
-	Type	: SDRAM
-	Width	: 32 bits
-	Size	: 64 mibibytes
-	Chip	: Two Micron MT48LC16M16A2TG-7E
-	CS		: MPC860T CS1*/UPMA
-	UPMA CONNECTIONS:
-		SDRAM A10	: GPLA0*
-		SDRAM CAS*	: GPLA2*
-		SDRAM WE*	: GPLA3*
-		SDRAM RAS*	: GPLA4*
-
-Boot memory:
-	Type	: FLASH
-	Width	: 8 bits
-	Size	: 16 mibibytes
-	Chip	: One Intel 28F128J3A (StrataFlash)
-	CS		: MPC860T CS0*/GPCM (this is the "boot" chip select)
-
-EEPROM memory:
-	Type	: Serial I2C EEPROM
-	Width	: 8 bits
-	Size	: 32 kibibytes
-	Chip	: One Atmel AT25C256
-	CS		: 0x50 (external I2C address pins on device are tied to GND)
-
-Filesystem memory:
-	Type	: NAND FLASH (Toshiba)
-	Width	: 8 bits (i.e. interface to DOC is 8 bits)
-	Size	: 32 mibibytes
-	Chip	: One DiskOnCHip Millenium Plus (DOC 2000+)
-	CS		: MPC860T CS2*/GPCM
-
-Network support:
-	MAC		: MPC86OT FEC (Fast Ethernet Controller)
-	PHY		: Intel LXT971A
-	MII Addr: 0x0 (hardwired on the board)
-	MII IRQ	:
-
-Console:
-	RS-232 on SMC1 (Maxim MAX3232 LVCMOS-RS232 level shifter)
-
-Real Time Clock:
-	Type	: Low power, I2C interface
-	Chip	: Maxim DS1337
-	CS		: Address 0x68 on I2C bus
-
-	The MPC860T's internal RTC has a defect in Mask rev D that increases
-	the current drain on the KAPWR line to 10 mA.  Since this is an
-	unreasonable amount of current draw for a RTC, and Motorola does not
-	plan to fix this in future mask revisions, a serial (I2C) RTC that
-	works has been included instead.  NOTE that the DS1337 can be
-	configured to output a 32768 Hz clock while the main power is on.
-	This clock output has been routed to the MPC860T's EXTAL pin to allow
-	the internal RTC to be used.  NOTE also that due to yet another
-	defect in the rev D mask, the RTC does not operate reliably when the
-	internal RTC divisor is set to use a 32768 Hz reference.  So just use
-	the I2C RTC.
-
-Miscellaneous:
-	Xilinx Virtex FPGA on CS3*/GPCM.
-	Virtex FPGA slave SelectMap interface on cs4*/UPMB.
-	Mil-Std 1553 databus interface on CS5*/GPCM.
-	Audio sounder (beeper) with digital volume control connected to SPKROUT.
-
-SC variant:
-	A reduced-feature version of the GEN860T port is also supported: GEN860T_SC.
-	The 'SC' variant only provides support for the Virtex FPGA, SDRAM main
-	memory, EEPROM and flash memory.  The system clock frequency is reduced
-	to 24 MHz.
-
-Issues:
-	The DOC 2000+ returns 0x40 as its device ID when probed using the method
-	desxribed in the DOC datasheet.  Unfortunately, the U-Boot DOC driver
-	does not recognize this device.  As of this writing, it seems that MTD
-	does not support the DOC 2000+ either.
-
-Status:
-	Everything appears to work except DOC support. As of this writing,
-	David Woodhouse has stated on the MTD mailing list that he has no
-	knowledge of the DOC Millineum Plus and therfore there is no support
-	in MTD for this device.  I wish I had known this sooner :(
