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.
