+U-Boot for a Musenki M-3/M-1 board
+---------------------------
+
+Musenki M-1 and M-3 have two banks of flash of 4MB or 8MB each.
+
+In board's notation, bank 0 is the one at the address of 0xFF800000
+and bank 1 is the one at the address of 0xFF000000.
+
+On power-up the processor jumps to the address of 0xFFF00100, the last
+megabyte of the bank 0 of flash.
+
+Thus, U-Boot is configured to reside in flash starting at the address of
+0xFFF00000.  The environment space is located in flash separately from
+U-Boot, at the address of 0xFF800000.
+
+There is a Davicom 9102A on-board, but I don't have it working yet.

+Hi,
+
+so this is the port to the Embedded Planet RPX Super Board.
+
+ATTENTION
+This code is only tested on the AY-Version, which is an early release with some
+hardware bugs. The main problem is that this board uses the default Hard Reset
+Configuration Word and not the 4 bytes located at start of FLASH because at
+0xFE000000 is no FLASH. The FLASH consists out of 4 chips each 16bits wide. Be
+carefull, the bytes are swapped. So DQ0-7 is the high byte, DQ8-15 ist the low
+byte.
+
+The icache can only manually be enabled after reset.
+The FLASH and main SDRAM is working with icache enabled.
+The local SDRAM can only be used as data memory when icache is enabled.
+If U-Boot runs in local SDRAM, TFTP does not work.
+The functions in mii_phy.c are all working. Call mii_phy_discover() out of
+eth_init() and solve the linker error.
+I2C, RTC/NVRAM and PCMCIA are not working yet.
+
+TODO
+The 32MB local SDRAM is working but not shown in the startup messages of
+U-Boot. If you locate U-Boot or any other program to this area it won't run.
+Turning the ichache off does not solve this problem.
+
+As I won't buy another RPX Super there might be some little work to do for you
+getting this U-Boot port running on the final board.

+
+This file contains basic information on the port of U-Boot to TQM8260.
+All the changes fit in the common U-Boot infrastructure, providing a
+new TQM8260-specific entry in makefiles. To build U-Boot for TQM8260,
+type "make TQM8260_config", edit the "include/config_TQM8260.h" file
+if necessary, then type "make".
+
+
+Common file modifications:
+--------------------------
+
+The following common files have been modified by this project:
+(starting from the ppcboot-0.9.3/ directory)
+
+MAKEALL			- TQM8260 entry added
+Makefile		- TQM8260_config entry added
+cpu/mpc8260/Makefile	- soft_i2c.o module added
+cpu/mpc8260/ether_scc.c	- TQM8260-specific definitions added, an obvious
+			  bug fixed (fcr -> scr)
+cpu/mpc8260/ether_fcc.c	- TQM8260-specific definitions added
+include/flash.h		- added definitions for the AM29LV640D Flash chip
+
+
+New files:
+----------
+
+The following new files have been added by this project:
+(starting from the ppcboot-0.9.3/ directory)
+
+board/tqm8260/		  - board-specific directory
+board/tqm8260/Makefile	  - board-specific makefile
+board/tqm8260/config.mk	  - config file
+board/tqm8260/flash.c	  - flash driver (for AM29LV640D)
+board/tqm8260/ppcboot.lds - linker script
+board/tqm8260/tqm8260.c	  - ioport and memory initialization
+cpu/mpc8260/soft_i2c.c	  - software i2c EEPROM driver
+include/config_TQM8260.h  - main configuration file
+
+
+New configuration options:
+--------------------------
+
+CONFIG_TQM8260
+
+	Main board-specific option (should be defined for TQM8260).
+
+CONFIG_82xx_CONS_SMC1
+
+	If defined, SMC1 will be used as the console
+
+CONFIG_82xx_CONS_SMC2
+
+	If defined, SMC2 will be used as the console
+
+CFG_INIT_LOCAL_SDRAM
+
+	If defined, the SDRAM on the local bus will be initialized and
+	mapped at BR2.
+
+
+Acceptance criteria tests:
+--------------------------
+
+The following tests have been conducted to validate the port of U-Boot
+to TQM8260:
+
+1. Operation on serial console:
+
+With the CONFIG_82xx_CONS_SMC1 option defined in the main configuration file,
+the U-Boot output appeared on the serial terminal connected to COM1 as
+follows:
+

+- BCR tweakage for the 8260 bus mode
+- SIUMCR tweakage enabling the MI interrupt (IRQ7)
+
+To simplify switching between the bus modes, a new configuration
+option (CONFIG_BUSMODE_60x) has been added to the "config_TQM8260.h"
+file. If it is defined, BCR will be configured for the 60x mode,
+otherwise - for the 8260 mode.
+
+Concerning the SIUMCR modification: it's hard to predict whether it
+will induce any problems on the other (60x mode) board. However, the
+problems (if they appear) should be easy to notice - if the board
+does not boot, it's most likely caused by the DPPC configuration in
+SIUMCR.

+This file contains status information for the port of U-Boot to the
+Galileo Evaluation Board.
+
+Author: Josh Huber <huber@mclx.com>
+	Mission Critical Linux, Inc.
+
+The support for the Galileo Evaluation board is fairly minimal now.
+It's sufficient to boot Linux, but doesn't provide too much more than
+what's required to do this.
+
+Both DUART channels are supported (to use the second one, you have to
+modify the board -- see the schematics for where to solder on the
+devices module).  The ethernet ports are supported, and the MPSC is
+supported as a console driver. (keep in mind that the kernel has no
+support for this yet)
+
+There are still occaisonal lockups with the MPSC console driver due to
+(we think!) overrun problems.  If you're looking for something stable
+to use for Linux development, consider sticking with the DUART console
+for now.
+
+Automatic memory sizing mostly works.  We've had problems with some
+combinations of memory.  Please send us email if you're having trouble
+with respect to the memory detection.
+
+Right now, only the 512k boot flash is supported.  Support for the
+16MB flash on the devices module is forthcoming.  Right now the flash
+is stored at the 256k boundry in flash, wasting a whole sector (64k!)
+for environment data.  This isn't really a big deal since we're not
+using the 512k for anything else. (Just U-Boot and the environment)
+
+Finally, here is a sample output session:
+
+U-Boot 1.0.0-pre1 (Jun  6 2001 - 12:45:11)
+
+Initializing...
+  CPU:   MPC7400 (altivec enabled) v2.9
+  Board: EVB64260
+  DRAM:  256 MB
+  FLASH: 512 kB
+  In:    serial
+  Out:   serial
+  Err:   serial
+
+=>
+
+The default configuration should be correct for the evaluation board,
+as it's shipped from Galileo.  Keep in mind that the default baudrate
+is set to 38400, 8N1.
+
+Good luck, and make sure to send any bugreports to us (or the
+u-boot-users list).

+This file contains status information for the port of U-Boot to the

+
+Author: Josh Huber <huber@mclx.com>
+	Mission Critical Linux, Inc.
+
+Currently the support for these CPUs is pretty minimal, but enough to
+get things going.  (much like the support for the Galileo Eval Board)
+
+There is a framework in place to enable the L2 cache, and to program
+the BATs.  Currently, there are still problems with the code which
+sets up the L2 cache, so it's not enabled. (IMHO, it shouldn't be
+anyway).  Additionally, there is support for enabling the MMU, which
+we also don't do.  The BATs are programmed just for the benefit of
+jumping into Linux in a sane configuration.
+
+Most of the code was based on other cpus supported by U-Boot.
+
+If you find any errors in the CPU setup code, please send us a note.
+
+Thanks,

+USB Support for PIP405 and MIP405 (UHCI)
+========================================
+
+The USB support is implemented on the base of the UHCI Host
+controller.
+
+Currently supported are USB Hubs, USB Keyboards and USB Floppys.
+Tested with a TEAC Floppy TEAC FD-05PUB and Chicony KU-8933 Keyboard.
+
+How it works:
+-------------
+
+The USB (at least the USB UHCI) needs a frame list (4k), transfer
+descripor and queue headers which are all located in the main memory.
+The UHCI allocates every milisecond the PCI bus and reads the current
+frame pointer. This may cause to crash the OS during boot. So the USB
+_MUST_ be stopped during OS boot. This is the reason, why the USB is
+NOT automatically started during start-up. If someone needs the USB
+he has to start it and should therefore be aware that he had to stop
+it before booting the OS.
+
+For USB keyboards this can be done by a script which is automatically
+started after the U-Boot is up and running. To boot an OS with a an
+USB keyboard another script is necessary, which first disables the
+USB and then executes the boot command. If the boot command fails,
+the script can reenable the USB kbd.
+
+Common USB Commands:
+- usb start:
+- usb reset:	    (re)starts the USB. All USB devices will be
+		    initialized and a device tree is build for them.
+- usb tree:	    shows all USB devices in a tree like display
+- usb info [dev]:   shows all USB infos of the device dev, or of all
+		    the devices
+- usb stop [f]:	    stops the USB. If f==1 the USB will also stop if
+		    an USB keyboard is assigned as stdin. The stdin
+		    is then switched to serial input.
+Storage USB Commands:
+- usb scan:	    scans the USB for storage devices.The USB must be
+		    running for this command (usb start)
+- usb device [dev]: show or set current USB staorage device
+- usb part [dev]:   print partition table of one or all USB storage
+		    devices
+- usb read addr blk# cnt:
+		    read `cnt' blocks starting at block `blk#'to
+		    memory address `addr'
+- usbboot addr dev:part:
+		    boot from USB device
+
+Config Switches:
+----------------
+CFG_CMD_USB	    enables basic USB support and the usb command
+CONFIG_USB_UHCI	    defines the lowlevel part.A lowlevel part must be defined if
+		    using CFG_CMD_USB
+CONFIG_USB_KEYBOARD enables the USB Keyboard
+CONFIG_USB_STORAGE  enables the USB storage devices

+ *   01-31-2000 DMW     Created
+ *   09-18-2000 SJH     Moved structure out of the Disk-On-Chip drivers
+ *			so it can be used by other NAND flash device
+ *			drivers. I also changed the copyright since none
+ *			of the original contents of this file are specific
+ *			to DoC devices. David can whack me with a baseball
+ *			bat later if I did something naughty.
+ *   10-11-2000 SJH     Added private NAND flash structure for driver
+ *   2000-10-13 BE      Moved out of 'nand.h' - avoids duplication.
