-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 :(
