The attached tarballs contains four new drivers to support the on-chip flash memory, RTC (wallclock), I2C and SPI units of the LPC2xxx controllers. The flash driver is not much more than a wrapper around the IAP routine of the boot rom. Since I can't test on other devices, it is currently limited to those LPC2xxx variants using two erase block sizes (8k and 64k) and containing 256k of flash memory, of which the upper 8x8k are usable. This is enough for RedBoot to support FIS and fconfig. It shouldn't be hard to extend the driver to fully support the simpler devices using all 8k blocks. -- %SYSTEM-F-ANARCHISM, The operating system has been overthrown
