+This file contains basic information on the port of U-Boot to IPHASE4539
+(Interphase 4539 T1/E1/J1 PMC Communications Controller).
+All the changes fit in the common U-Boot infrastructure, providing a new
+IPHASE4539-specific entry in makefiles. To build U-Boot for IPHASE4539,
+type "make IPHASE4539_config", edit the "include/config_IPHASE4539.h"
+file if necessary, then type "make".
+
+
+Common file modifications:
+--------------------------
+
+The following common files have been modified by this project:
+(starting from the ppcboot-1.1.5/ directory)
+
+MAKEALL - IPHASE4539 entry added
+Makefile - IPHASE4539_config entry added
+
+
+New files:
+----------
+
+The following new files have been added by this project:
+(starting from the ppcboot-1.1.5/ directory)
+
+board/iphase4539/ - board-specific directory
+board/iphase4539/Makefile - board-specific makefile
+board/iphase4539/config.mk - config file
+board/iphase4539/flash.c - flash driver (for AM29LV033C)
+board/iphase4539/ppcboot.lds - linker script
+board/iphase4539/iphase4539.c - ioport and memory initialization
+include/config_IPHASE4539.h - main configuration file
+
+
+New configuration options:
+--------------------------
+
+CONFIG_IPHASE4539
+
+ Main board-specific option (should be defined for IPHASE4539).
+
+
+Acceptance criteria tests:
+--------------------------
+
+The following tests have been conducted to validate the port of U-Boot
+to IPHASE4539:
+
+1. Operation on serial console:
+
+With SMC1 defined as console in the main configuration file, the U-Boot
+output appeared on the serial terminal connected to the 2.5mm stereo jack
+connector as follows:
+
+------------------------------------------------------------------------------
+=> help
+base - print or set address offset
+bdinfo - print Board Info structure
+bootm - boot application image from memory
+bootp - boot image via network using BootP/TFTP protocol
+bootd - boot default, i.e., run 'bootcmd'
+cmp - memory compare
+coninfo - print console devices and informations
+cp - memory copy
+crc32 - checksum calculation
+dcache - enable or disable data cache
+echo - echo args to console
+erase - erase FLASH memory
+flinfo - print FLASH memory information
+go - start application at address 'addr'
+help - print online help
+icache - enable or disable instruction cache
+iminfo - print header information for application image
+loadb - load binary file over serial line (kermit mode)
+loads - load S-Record file over serial line
+loop - infinite loop on address range
+md - memory display
+mm - memory modify (auto-incrementing)
+mtest - simple RAM test
+mw - memory write (fill)
+nm - memory modify (constant address)
+printenv- print environment variables
+protect - enable or disable FLASH write protection
+rarpboot- boot image via network using RARP/TFTP protocol
+reset - Perform RESET of the CPU
+run - run commands in an environment variable
+saveenv - save environment variables to persistent storage
+setenv - set environment variables
+sleep - delay execution for some time
+source - run script from memory
+tftpboot- boot image via network using TFTP protocol
+ and env variables ipaddr and serverip
+version - print monitor version
+? - alias for 'help'

+2. Flash driver operation
+
+The following sequence was performed to test the "flinfo" command:

+
+Note: the Hardware Configuration Word (HWC) of the 8260 is on the
+first sector of the flash and should not be touched. The U-Boot
+environment variables are stored on second sector and U-Boot
+starts at the address 0xFFB00000.
