-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).
-
-Josh

-The EVB-64260-750CX is quite similar to the EVB-64260-BP already
-supported except the following differences:
-* It has an IBM-750CXe soldiered on board instead of the slot-1 in the
- BP.
-* It has a single PCI male connector instead of the 4 PCI female
- connectors on the BP. It also gets power trough the PCI connector.
-* It has only a single DIMM slot instead of the 2 slots in the BP.

-Freescale MPC7448hpc2 (Taiga) board
-===================================
-
-Created 08/11/2006 Roy Zang
---------------------------
-MPC7448hpc2 (Taiga) board is a high-performance PowerPC server reference
-design, which is optimized for high speed throughput between the processor and
-the memory, disk drive and Ethernet port subsystems.
-
-MPC7448hpc2(Taiga) is designed to the micro-ATX chassis, allowing it to be
-used in 1U or 2U rack-mount chassis¡¯, as well as in standard ATX/Micro-ATX
-chassis.
-
-Building U-Boot
-------------------
-The mpc7448hpc2 code base is known to compile using:
- Binutils 2.15, Gcc 3.4.3, Glibc 2.3.3
-
- $ make mpc7448hpc2_config
- Configuring for mpc7448hpc2 board...
-
- $ make
-
-Memory Map
-----------
-
-The memory map is setup for Linux to operate properly.
-
-The mapping is:
-
- Range Start Range End Definition Size
-
- 0x0000_0000 0x7fff_ffff DDR 2G
- 0xe000_0000 0xe7ff_ffff PCI Memory 128M
- 0xfa00_0000 0xfaff_ffff PCI IO 16M
- 0xfb00_0000 0xfbff_ffff PCI Config 16M
- 0xfc00_0000 0xfc0f_ffff NVRAM/CADMUS 1M
- 0xfe00_0000 0xfeff_ffff PromJet 16M
- 0xff00_0000 0xff80_0000 FLASH (boot flash) 8M
- 0xff80_0000 0xffff_ffff FLASH (second half flash) 8M
-
-Using Flash
------------
-
-The MPC7448hpc2 board has two "banks" of flash, each 8MB in size
-(2^23 = 0x00800000).
-
-Note: the "bank" here refers to half of the flash. In fact, there is only one
-bank of flash, which is divided into low and high half. Each is controlled by
-the most significant bit of the address bus. The so called "bank" is only for
-convenience.
-
-There is a switch which allows the "bank" to be selected. The switch
-settings for updating flash are given below.
-
-The u-boot commands for copying the boot-bank into the secondary bank are
-as follows:
-
- erase ff800000 ff880000
- cp.b ff000000 ff800000 80000
-
-U-boot commands for downloading an image via tftp and flashing
-it into the secondary bank:
-
- tftp 10000 <u-boot.bin.image>
- erase ff000000 ff080000
- cp.b 10000 ff000000 80000
-
-After copying the image into the second bank of flash, be sure to toggle
-SW3[4] on board before resetting the board in order to set the
-secondary bank as the boot-bank.
-
-Board Switches
-----------------------
-
-Most switches on the board should not be changed. The most frequent
-user-settable switches on the board are used to configure
-the flash banks and determining the PCI frequency.
