209 has different content depending on platform, of course. 430 has different content depending on platform, of course.
431 For the EBSA-285, flush caches when writing vectors and the like,
432 since RAM startup occurs with caches enabled, otherwise you get
433 mysterious traps as CygMon is entered regardless at the first
434 clock tick, for example. This may be taken out again as ROM
435 startup is dealt with via PLATFORM_SETUP1, but for now...
