Board description
-----------------
Clock rate: 50MHz - 133MHz.
Bus width: 32 bit Flash, 32 bit DRAM
FLASH: 2-8MB
RAM: 32-256MB SDRAM
Installation
------------
<tbd>
Port Description
Console driver
---------------
This BSP contains a console driver for polled and interrupt-driven
operation. It supports SCCs and SMCs.
During BSP configuration, various variables can be set to activate a
certain channels and to specify the console channel:
CONS_SMC1_MODE, CONS_SMC2_MODE, CONS_SCC[1-4]_MODE can be set to
CONS_MODE_UNUSED, CONS_MODE_POLLED or CONS_MODE_IRQ
The driver always uses termios.
printk() and debug output
-----------------------
<tbd>
Floating-point
--------------
The MPC8xx do not have floating-point units. All code should
get compiled with the appropriate -mcpu flag. The nof variants of the gcc
runtime libraries should be used for linking.
Miscellaneous
-------------
All development was based on the mbx8xx and gen68360 port.
Test Configuration
------------------
Board: pghplus (
CPU: Motorola MPC866T
Clock Speed: 133MHz
RAM: 64MByte
Cache Configuration: Instruction cache on; data cache on, copyback mode.
