-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.
