IDT 79S332 board (big-endian)
=============================

This kit is set up for the following board configuration:

     System clock	66.5 MHz
     DRAM 		32MB SODIMM at 0x00000000
     SRAM		1MB located after SODIMM
     Flash width	8 or 32 bit wide
     Console UART	RC32332 internal
     CPU Intr5		Internal CPU count/compare timer

All of these board-specific parameters are defined in the file
../idt33x/sbd.h. They can be patched in that file or, more cleanly, in
the board-specific file sbd.mk which is in this directory, for example 

     KITFLAGS = -DSYSCLK_HZ=50000000 -DIDT33X_CONSOLE_INTERN=0

adding this line will build a kit with a 50 MHz system clock, and
using the external (Am85c30) UART as the console and debug port.

Note that the system clock frequency must be set correctly or ROMmable
code won't work: there is no way for the software determine the value
dynamically, and the system clock directly feeds the UART clock, so
wrong frequency equals bad baud rate. The value also determines the
setting of various memory controller parameters, which if set
incorrectly may cause flaky behaviour. When running in RAM under
IDT/sim an incorrect frequency setting will generate incorrect
benchmark results.
