1 MCF52277 specific Options/Settings
====================================
1.1 pre-loader is no longer suppoer in this coldfire family
1.2 Configuration settings for M52277EVB Development Board
CONFIG_MCF5227x -- define for all MCF5227x CPUs

CONFIG_BAUDRATE -- define UART baudrate
CONFIG_MCFRTC -- define to use common CF RTC driver
CFG_MCFRTC_BASE -- provide base address for RTC in immap.h
CFG_RTC_OSCILLATOR -- define RTC clock frequency
RTC_DEBUG -- define to show RTC debug message
CONFIG_CMD_DATE -- enable to use date feature in u-boot
CONFIG_MCFTMR -- define to use DMA timer
CONFIG_MCFPIT -- define to use PIT timer
CONFIG_FSL_I2C -- define to use FSL common I2C driver
CONFIG_HARD_I2C -- define for I2C hardware support

CFG_CSn_MASK -- defines the Chip Select Mask register
CFG_CSn_CTRL -- defines the Chip Select Control register
CFG_SDRAM_BASE -- defines the DRAM Base
CONFIG_LCD and CONFIG_CMD_USB are not supported in this current u-boot,
update will be provided at later time
2. MEMORY MAP UNDER U-BOOT AND LINUX KERNEL
===========================================
2.1. System memory map:
Flash: 0x00000000-0x3FFFFFFF (1024MB)
DDR: 0x40000000-0x7FFFFFFF (1024MB)
SRAM: 0x80000000-0x8FFFFFFF (256MB)
IP: 0xF0000000-0xFFFFFFFF (256MB)
2.2. 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:
Flash0: 0x00000000-0x00FFFFFF (16MB)
DDR: 0x40000000-0x4FFFFFFF (64MB)
SRAM: 0x80000000-0x80007FFF (32KB)
IP: 0xFC000000-0xFC0FFFFF (64KB)
3. COMPILATION
==============
3.1 To create U-Boot the gcc-4.1-xx compiler set (ColdFire ELF or
uClinux version) from codesourcery.com was used. Download it from:
http://www.codesourcery.com/gnu_toolchains/coldfire/download.html
3.2 Compilation
export CROSS_COMPILE=cross-compile-prefix
cd u-boot-1.x.x
make distclean
make M52277EVB_config
make
