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.

|

|

* 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.
