+
+ 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, Parallel
+
+CPU board: - DRAM: 16 MB
+ - FLASH: 512 KB + (2 * 4 MB)
+ - NVRAM: 128 KB
+ - 1 Serial link
+ - 2 Ethernet 10 BaseT Channels
+
+On power-up the processor jumps to the address of 0x02000100
+
+Thus, U-Boot is configured to reside in flash starting at the address of
+0x02001000. The environment space is located in NVRAM separately from
+U-Boot, at the address of 0x03000000.
