Add support for the GOEPEL PicoTAP programmer
http://www.goepel.com/en/jtagboundary-scan/hardware/picotap.html
This device is actually a JTAG adapter, but since it uses standard
FT2232 A interface pins, it can be easily used as SPI programmer
(tested it here successfully). PicoTAP supports only 5V output, so one
needs to reduce this to 3.3V in a same manner as DLP Design DLP-USB1232H, see
http://flashrom.org/FT2232SPI_Programmer#DLP_Design_DLP-USB1232H
for details.
The PicoTAP pin-out is as follows:
PicoTAP | SPI
---------+-------
TCK | SCLK
TMS | CS#
TDI | SO
TDO | SI
/TRST | -
GND | GND
+5V | VCC, HOLD# & WP# after 3.3V regulator
I managed to run PicoTAP in 10MHz, 15MHz and 30MHz modes (by forcing
DIVIDE_BY), against SST25VF016B SPI flash, read/write/erase all worked
fine (write seems somewhat slow).
Corresponding to flashrom svn r1453.
