 ## Detect flash and adjust /flash-memory properties.

 ## !! Reset the system - makes PITA on Espresso server
Note, Roxy can reset itself easily if kernel panics, so it must be doable...

 ## Use hardware multiply & divide
 ## printf with better %-sequences
 ## Probe memory through mappings, not bypass.
 ## Memory probing returns BS when bank 0 is 8MB, bank 1 is 32MB.
I know it's possible to read DIMM IDs. They have serial SROMs. But how?
 ## /proc/openprom does not show any properties, tree is ok. /options ?
 ## Warn during build/run that size > 240K
By some reason mrcoffee eats 224K vs. 160K in espresso - what's the matter?
(we think - iommu *aligned* table, it's HUGE)
 ## Serial console support
(Since ID07 there is a stub for this, works ok but not general enough)
Autoswitching
 ## Cursor in hconsole; make vconsole use it.

 ## Rewrite Gero's UDP/IP with sane buffering arrangement.
Current code is way to fragile with a lot of assumptions.
Try to ping the node and observe the result.
