Log: Add atapromise programmer
Supported controllers are Promise PDC20262 (FastTrak66/Ultra66), PDC20265 (FastTrak100 Lite/Ultra100), PDC20267 (FastTrak100/Ultra100). At least the Ultra100 only has address lines A0-A14 wired up, limiting addressable chip size to 32 kB. The flash chips mounted on those controllers usually is 128 kB, i.e. parts of the flash chip are inaccessible. As a workaround, the driver implicitly truncates the size of all flash chips to 32 kB. Works well for the factory installed flash. Do NOT use as a generic programmer for chips >32 kB.
