Add initial Atmel AT49LH002 FWH/LPC chip support
The chip code is untested, only one erase function out of two is currently implemented, and unlocking/printlocking is not yet supported. Thanks Mattias Mattsson <vitplister@gmail.com> for the initial patch! Corresponding to flashrom svn r1434. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
