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. Corresponding to flashrom svn r1916. Signed-off-by: Joseph C.

+ * In the absence of any public docs on the PDC2026x family, this programmer was created through a mix of
+ * reverse-engineering and trial and error.
+ *
+ * The only device tested is an Ultra100 controller, but the logic for programming the other 2026x controllers
+ * is the same, so it should, in theory, work for those as well.
+ *
+ * While the tested Ultra100 controller used a 128 kB MX29F001T chip, A16 and A15 showed continuity to ground,
+ * thus limiting the the programmer on this card to 32 kB. Without other controllers to test this programmer on,
+ * this is currently a hard limit. Note that ROM files for these controllers are 16 kB only.
+ *
+ * Since flashrom does not support accessing flash chips larger than the size limit of the programmer (the
+ * tested Ultra100 uses a 128 kB MX29F001T chip), the chip size is hackishly adjusted in atapromise_limit_chip.
