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)
SW11[2]='OFF for 8560, ON for 8540' (single switch to 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)
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
2.1. For the initial bringup, we adopted a consistent memory scheme

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/ppc/configs/mpc8540_ads_defconfig

4.1 When connecting with kermit, the following commands must be present.in
