AT91R40008/Ethernut 3 configuration
Moved board specific settings from target/at91r40008.cfg to a new file board/ethernut3.cfg. Set correct CPUTAPID. Reset delay increased, see MIC2775 data sheet. Increased work area size from 16k to 128k. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
