Here are some patches to the gen68360 BSP. The improvements include:
Boot prom run-time selection of DRAM size (1/4/16 Mbytes)
Full 32-bit ethernet address obtained from boot prom.
Updated README.
I've included a version of make/custom/gen68360.cfg that works with
this. Note that I've removed the option of using `-m68020
-msoft-float -mno-bitfield' as an alternative to using `-mcpu32'.
The alternative won't work with the new system (since it predefines
__mc68020__ and not __mcpu32__), and didn't really work before anyway
(since the newlib that gets linked was built with `-m68020
-msoft-float' and so could contain bitfield operators).
While trying to work through this problem I decided that the
build-time selection of the console I/O operation (polling or
interrupt) was too clumsy. Here's a patch that allows run-time
(actually init-time) selection of the console I/O mode.
It also shows the need for another `flags' or `options' field in
the rtems_driver_address_table structure...
