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

0. Toolchain

    The Binutils in current ELDK toolchain will not support MPC85xx
    chip.  You need to use binutils-2.14.tar.bz2 (or newer) from
    http://ftp.gnu.org/gnu/binutils.

    The 8540/8560 ADS code base is known to compile using:
	gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a)


1. SWITCH SETTINGS & JUMPERS

1.0 Nomenclature

    For some reason, the HW designers describe the switch settings
    in terms of 0 and 1, and then map that to physical switches where
    the label "On" refers to logic 0 and "Off" (unlabeled) is logic 1.
    Luckily, we're SW types and virtual settings are handled daily.

    The switches for the Rev A board are numbered differently than
    for the Pilot board.  Oh yeah.

    Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
    bits may contribute to signals that are numbered based at 0,
    and some of those signals may be high-bit-number-0 too.  Heed
    well the names and labels and do not get confused.

    "Off" == 1
    "On"  == 0

    SW18 is switch 18 as silk-screened onto the board.
    SW4[8] is the bit labeled 8 on Switch 4.
    SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2
    SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3

1.1 For the MPC85xxADS Pilot Board

    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 8560, ON for 8540' (toggle 8540.8560 mode)
    SW11[7]='ON' (rev2), 'OFF' (rev1)
    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)

    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. For example, if at 66MHz your system
    clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10.

	SW17[8] ------+	   SW6
	SW15[1] ----+ |	  [0:1]
		    V V	   V V
	33MHz	    1 1	   1 0
	66MHz	    0 0	   0 1

    Hmmm... That SW6 setting description is incomplete but it works.


1.3 For the MPC85xxADS Rev A Board

    As shipped, the board should be a 33MHz PCI bus with a CPU Clock
    rate of 825 +/- fuzz:

	Clocks: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz, LBC:	82 MHz

    For 33MHz PCI, the switch settings should be like this:

	SW18[7:1] = 0100001 = M==33 =>	  33MHz
	SW18[8]	  =	  1	    => PWD Divider == 16
	SW16[1:2] =	 11	    => N == 16 as PWD==1

    Use the magical formula:
	Fout (MHz) = 16 * M / N = 16 * 33 / 16 = 33 MHz

	SW7[1:4]  =    1010 = 10    => 10 x 33	 = 330	CCB Sysclk
	SW7[5:6]  =	 01	    => 5:2 x 330 = 825	Core clock


    For 66MHz PCI, the switch settings should be like this:

	SW18[7:1] = 0100001 = M==33 =>	  33MHz
	SW18[8]	  =	  0	    => PWD Divider == 1
	SW16[1:2] =	 01	    => N == 8 as PWD == 0

    Use the magical formula:
	Fout (MHz) = 16 * M / N = 16 * 33 / 8 = 66 MHz

	SW7[1:4]  =    0101 =  5    => 5 x 66	 = 330	CCB Sysclk
	SW7[5:6]  =	 01	    => 5:2 x 330 = 825	Core clock

    In order to use PCI-X (only in the first PCI slot.  The one with
    the RIO connector), you need to set SW1[4] (config) to 1 (off).
    Also, configure the board to run PCI at 66 MHz.

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:

     0x0000_0000     0x7fff_ffff     DDR		     2G
     0x8000_0000     0x9fff_ffff     PCI MEM		     512M
     0xc000_0000     0xdfff_ffff     Rapid IO		     512M
     0xe000_0000     0xe00f_ffff     CCSR		     1M
     0xe200_0000     0xe2ff_ffff     PCI IO		     16M
     0xf000_0000     0xf7ff_ffff     SDRAM		     128M
     0xf800_0000     0xf80f_ffff     BCSR		     1M
     0xff00_0000     0xffff_ffff     FLASH (boot bank)	     16M

2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You
    can download them from linuxppc-2.4 public source. Please make sure the
    kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
    default configuration files as your starting points to configure the
    kernel:
	arch/powerpc/configs/mpc8540_ads_defconfig
	arch/powerpc/configs/mpc8560_ads_defconfig

3. DEFINITIONS AND COMPILATION

3.1 Explanation on NEW definitions in:
	include/configs/MPC8540ADS.h
	include/configs/MPC8560ADS.h

    CONFIG_BOOKE	    BOOKE(e.g. Motorola MPC85xx, AMCC 440, etc)
    CONFIG_E500		    BOOKE e500 family(Motorola)
    CONFIG_MPC85xx	    MPC8540,MPC8560 and their derivatives
    CONFIG_ARCH_MPC8540	    MPC8540 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_SYS_FSL_ERRATUM_DDR_MSYNC_IN	    DLL fix on some ADS boards needed
			    for more stability.
    CONFIG_HAS_FEC	    If an FEC is on chip, set to 1, else 0.

Other than the above definitions, the rest in the config files are
straightforward.


3.2 Compilation

    Assuming you're using BASH shell:

	export CROSS_COMPILE=your-cross-compile-prefix
	cd u-boot
	make distclean
	make MPC8560ADS_config (or make MPC8540ADS_config)
	make

4.  Notes:

4.1 When connecting with kermit, the following commands must be present.in
    your .kermrc file. These are especially important when booting as
    MPC8560, as the serial console will not work without them:

	set speed 115200
	set carrier-watch off
	set handshake none
	set flow-control none
	robust


4.2 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

4.3 If you're one of the early developers using the Rev1 8540/8560 chips,
    please use U-Boot 1.0.0, as the newer silicon will only support Rev2
    and future revisions of 8540/8560.


4.4 Reflash U-Boot Image using U-Boot

    tftp 10000 u-boot.bin
    protect off fff80000 ffffffff
    erase fff80000 ffffffff
    cp.b 10000 fff80000 80000


4.5 Reflash U-Boot with a BDI-2000

    BDI> erase 0xFFF80000 0x4000 0x20
    BDI> prog 0xfff80000 u-boot.bin.8560ads
    BDI> verify

9aea9530	144	CONFIG_DDR_ECC only for ECC DDR module

	149	Other than the above definitions, the rest in the config files are

42d1f039	154
0ac6f8b7 WD	155	Assuming you're using BASH shell:
	156
	157	export CROSS_COMPILE=your-cross-compile-prefix
	158	cd u-boot
	159	make distclean
	160	make MPC8560ADS_config (or make MPC8540ADS_config)
	161	make

547b4cb2	165	4.1 When connecting with kermit, the following commands must be present.in
0ac6f8b7 WD	166	your .kermrc file. These are especially important when booting as
	167	MPC8560, as the serial console will not work without them:
	168
	169	set speed 115200
	170	set carrier-watch off
	171	set handshake none
	172	set flow-control none
	173	robust
	174
	175
	176	4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC
	177	ethernet. If that happens, you can try the following steps to make
	178	network work:
	179
	180	MPC8560ADS>tftp 1000000 pImage
	181	(if it hangs, use Ctrl-C to quit)
	182	MPC8560ADS>nm fdf24524
	183	>0
	184	>1
	185	>. (to quit this memory operation)
	186	MPC8560ADS>tftp 1000000 pImage
	187
	188	4.3 If you're one of the early developers using the Rev1 8540/8560 chips,
	189	please use U-Boot 1.0.0, as the newer silicon will only support Rev2
	190	and future revisions of 8540/8560.
