I am looking for a reputable single-board computer or development board
kit that has these features. any suggestions?

* can act as a SPI (synchronous serial port) slave with clock frequency
anywhere in the 5-12MHz range & has some kind of FIFO (so I don't have
to handle an interrupt for each incoming byte/word). This is the most
important requirement & I'm having a hard time finding docs on
single-board computers that meet it.

* has >= 16MB RAM onboard

* has SD card slot (compact flash acceptible but less preferable) &
cards are hot-pluggable

* has either an ethernet jack and/or USB device (fullspeed or
highspeed) jack. USB probably preferable; I want to plug this thing
into a PC to exchange data.

* has some kind of external address/data bus that I can hook up a few
things on a small daughterboard

* is likely to be around for at least 5 years

* has a decent software development environment that's not outrageously
expensive. Would prefer no OS or a simple RTOS, not WinCE.

* real-time-clock is a very-nice-to-have but I can probably live
without it.

* RS232 UART is a very-nice-to-have but I can probably live without it.

I've been looking at some PXA270 single-board computers, they seem like
they might a good fit, but can't find the documentation on whether it
can handle my SPI slave requirement. TI 5509A DSP evaluation board also
looks ok, and I'm familiar with Code Composer as the IDE, but my only
reservation is that it forces me to use USB (no ethernet, no UART
unless I put one on a daughterboard & connect it to CPU via parallel
interface).
