+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_M52277		-- define for all Freescale MCF52277 CPUs
+CONFIG_M52277EVB	-- define for M52277EVB board
+
+CONFIG_MCFUART		-- define to use common CF Uart driver
+CFG_UART_PORT		-- define UART port number, start with 0, 1 and 2
+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

+CFG_IMMR		-- define for MBAR offset
+
+CFG_MBAR		-- define MBAR offset
+
+CONFIG_MONITOR_IS_IN_RAM -- Not support
+
+CFG_INIT_RAM_ADDR	-- defines the base address of the MCF52277 internal SRAM
+
+CFG_CSn_BASE	-- defines the Chip Select Base register
+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
