Hello,
below is my patch against the current 1.2 CVS version of hal_platform_setup.h
to get the Neponset Expansion Board working unter Ecos/RedBoot.
This patch uses the timings as in the bootldr bootloader for LINUX. It works
perfectly for me (i use BootLdr to boot a 2.4.6 Linux kernel and use PCMCIA
through the SA1111 quite heavily).

I plan to look at this, but it may require some configury since these changes
seem to be very dependent upon the Assabet revision.
I'll let you know when & how they have been integrated into the CVS sources.
