4.5.1

Clock

The eLBC clock is generated by platform clock. The divisor is configured by CLKDIV in Clock
Ratio Register (LCRR). The divisor is 32 when GPCM is selected as RCW source. So the eLBC
clock is platform clock / 32 = 800MHz / 32 = 25MHz.

4.5.2

NOR Flash

The NOR FLASH is attached to the GPCM on local bus and works at 16-bit mode.

The NOR FLASH is Numonyx™ PC28F00 BM29EW H. Its size is 2Gb/ 256MB. It has 2048 uniform
blocks, 128K bytes or 64K words each.

The physical address for NOR FLASH is 0xFE0000000 - 0xFEFFFFFFF.

The NOR FLASH should contain RCW data, u-boot image, u-boot environment variables, kernel
image, device tree blob, RAMDISK image and FMAN ucode image. The detailed map is
described in the following table:N
