=============================================================================	     U-Boot port on the LEOX's ELPT860 CPU board	     -------------------------------------------LEOX.org is about the development of free hardware and software resources	 for system on chip.For more information, contact The LEOX team <team@leox.org>References:~~~~~~~~~~    1) Get the last stable release from denx.de:	   o ftp://ftp.denx.de/pub/u-boot/u-boot-0.2.0.tar.bz2    2) Get the current CVS snapshot:	   o cvs -d:pserver:anonymous@cvs.u-boot.sourceforge.net:/cvsroot/u-boot login	   o cvs -z6 -d:pserver:anonymous@cvs.u-boot.sourceforge.net:/cvsroot/u-boot co -P u-boot=============================================================================The ELPT860 CPU board has the following features:Processor:	- MPC860T @ 50MHz		- PowerPC Core		- 65 MIPS		- Caches: D->4KB, I->4KB		- CPM: 4 SCCs, 2 SMCs		- Ethernet 10/100		- SPI, I2C, PCMCIA, ParallelCPU board:	- DRAM:   16 MB		- FLASH: 512 KB + (2 * 4 MB)		- NVRAM: 128 KB		- 1 Serial link		- 2 Ethernet 10 BaseT ChannelsOn power-up the processor jumps to the address of 0x02000100Thus, U-Boot is configured to reside in flash starting at the address of0x02001000.  The environment space is located in NVRAM separately fromU-Boot, at the address of 0x03000000.=============================================================================			U-Boot test results=============================================================================################################################### Operation on the serial console (SMC1)##############################U-Boot 0.2.2 (Jan 19 2003 - 11:08:39)CPU:   XPC860xxZPnnB at 50 MHz: 4 kB I-Cache 4 kB D-Cache FEC present	 *** Warning: CPU Core has Silicon Bugs -- Check the Errata ***Board: ### No HW ID - assuming ELPT860DRAM:  16 MBFLASH: 512 kBIn:    serialOut:   serialErr:   serialNet:   SCC ETHERNETType "run nfsboot" to mount root filesystem over NFSHit any key to stop autoboot:  0LEOX_elpt860: helpaskenv  - get environment variables from stdinautoscr - run script from memorybase    - print or set address offsetbdinfo  - print Board Info structurebootm   - boot application image from memorybootp   - boot image via network using BootP/TFTP protocolbootd   - boot default, i.e., run 'bootcmd'cmp     - memory compareconinfo - print console devices and informationscp      - memory copycrc32   - checksum calculationecho    - echo args to consoleerase   - erase FLASH memoryflinfo  - print FLASH memory informationgo      - start application at address 'addr'help    - print online helpiminfo  - print header information for application imageloadb   - load binary file over serial line (kermit mode)loads   - load S-Record file over serial lineloop    - infinite loop on address rangemd      - memory displaymm      - memory modify (auto-incrementing)mtest   - simple RAM testmw      - memory write (fill)nm      - memory modify (constant address)printenv- print environment variablesprotect - enable or disable FLASH write protectionrarpboot- boot image via network using RARP/TFTP protocolreset   - Perform RESET of the CPUrun     - run commands in an environment variablesaveenv - save environment variables to persistent storagesetenv  - set environment variablessleep   - delay execution for some timetftpboot- boot image via network using TFTP protocol	       and env variables ipaddr and serveripversion - print monitor version?
