Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am running ltib linux on P1022RDK (P1022 Core) platform. I have 512 MB = 0x20000000 memory. I want my linux kernel to use second half of the board memory (i.e from 256 MB to 512 MB) and want first half of memory to be reserved for some other purpose. For this I am building linux kernel using ltib. For that purpose I am setting following kernel configuration.
Please suggest if I am doing it the right way.
CONFIG_LOWMEM_SIZE = 0x10000000 # 256 MB
CONFIG_PHYSICAL_START = 0x10000000 # Starting from 256MB (second half of memory)
On the Uboot I am loading the kernel as following way
