     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
