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 autoscr - run script from memory 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 tftpboot- boot image via network using TFTP protocol and env variables ipaddr and serverip version - print monitor version ? - alias for 'help' => ------------------------------------------------------------------------------ 2.

The U-Boot environment variables are stored on second sector and U-Boot starts at the address 0xFFB00000.
