-----------------------------------------

0. Toolchain
The Binutils in current ELDK toolchain will not support MPC85xx chip. You need
use the newest binutils-2.14.tar.bz2 from http://ftp.gnu.org/gnu/binutils.

1. SWITCH SETTINGS & JUMPERS
1.1 First, make sure the board default setting is consistent with the document
    shipped with your board. Then apply the following changes:
    SW3[1-6]="all OFF"  (boot from 32bit flash, no boot sequence is used)
    SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560)
    SW11[2]='OFF for dracom, ON for draco' (single switch to toggle draco.dracom mode)
    SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector)
    SW22[1-4]="OFF OFF ON OFF"
    SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF"
    J1 = "Enable Prog" (Make sure your flash is programmable for development)
    Ethernet PHY connectors(J47,J56) should be removed if you want to use the ethernet.
1.2 If you want to test PCI functionality with a 33Mhz PCI card, you will have to change
    the system clock from the default 66Mhz to 33Mhz by  setting SW15[1]="OFF" and
    SW17[8]="OFF". After that you may also need double your platform clock(SW6) because
    the system clock is now only half of its original value.
1.3 SW6 is a very important switch, it decides your platform clock and CPU clock based on
    the on-board system clock(default 66MHz). Check the document along with your board
    for details.

2. MEMORY MAP TO WORK WITH LINUX KERNEL
2.1. For the initial bringup, we adopted a consistent memory scheme between u-boot and
    linux kernel, you can customize it based on your system requirements:
      DDR:          0x00000000-0x1fffffff (max 512MB)
      PCI:          0xe0000000-0xefffffff (256MB)
      RIO:          0xf0000000-0xf7ffffff (128MB)
      Local SDRAM:  0xf8000000-0xfbffffff (64MB)
      Local CSx:    0xfc000000-0xfdefffff (31MB) BCSR,RTC,ATM config,etc.
      CCSRBAR:      0xfdf00000-0xfdffffff (1MB)
      Flash:        0xfe000000-0xffffffff (max 32MB)
2.2  We are submitting Linux kernel patches for MPC8540 and MPC8560. Hope you will be
     able to download them from linuxppc-2.4 public source by the time you are reading
     this. Please make sure the kernel's ppcboot.h is consistent with U-Boot's u-boot.h,
     then you can use two default configuration files in the kernel source as a test:
	arch/ppc/configs/mpc8540ads_defconfig
	arch/ppc/configs/mpc8560ads_defconfig

3. DEFINITIONS AND COMPILATION
3.1 Explanation on NEW definitions in include/configs/MPC8540ADS.h and include/
    configs/MPC8560ADS.h
    CONFIG_BOOKE            BOOKE(e.g. Motorola MPC85xx, IBM 440, etc)
    CONFIG_E500             BOOKE e500 family(Motorola)
    CONFIG_MPC85xx          MPC8540,MPC8560 and their derivatives
    CONFIG_MPC85xx_REV1     MPC85xx Rev 1 Chip, in general you will use a Rev2
			    chip from Nov.2003. If you still see this definition
			    while you have a Rev2(and newer) chip,undef this.
    CONFIG_MPC8540          MPC8540 specific
    CONFIG_MPC8560          MPC8560 specific
    CONFIG_MPC8540ADS       MPC8540ADS board specific
    CONFIG_MPC8560ADS       MPC8560ADS board specific
    CONFIG_TSEC_ENET        Use on-chip 10/100/1000 ethernet for networking
    CONFIG_SPD_EEPROM       Use SPD EEPROM for DDR auto configuration, you can also
			    manual config the DDR after undef this definition.
    CONFIG_DDR_ECC          only for ECC DDR module
    CONFIG_DDR_DLL          possible DLL fix needed for Rev1 chip for more stability.
			    you can disable this if you're having a newer chip.
    CONFIG_RAM_AS_FLASH     after define this, you can load U-Boot into localbus
			    SDRAM and treat localbus SDRAM as a flash. We use this
			    memory based U-Boot before flash is working while Metrowerks
			    and Windriver are still working on their flash/JTAG tools.
			    if you can program the flash directly, undef this.
    Other than the above definitions, the rest in the config files are straightforward.


3.2 Compilation
   export CROSS_COMPILE=your-cross-compile-prefix(assuming you're using BASH shell)
   cd u-boot
   make distclean
   make MPC8560ADS_config (or make MPC8540ADS_config)
   make

4.  Note on the 10/100/1000 Ethernet controller:
4.1 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC ethernet. If that
   happens, you can try the following steps to make network work:
   MPC8560ADS>tftp 1000000 pImage
   (if it hangs, use Ctrl-C to quit)
   MPC8560ADS>nm fdf24524
   >0
   >1
   >. (to quit this memory operation)
   MPC8560ADS>tftp 1000000 pImage
