Hi,
here's a patch which adds basic support for the Toshiba TMPA9xx series
ARM9 microcontrollers.
jtag> detect
IR length: 4
Chain length: 1
Device Id: 00000111100100100110000000110001 (0x07926031)
Manufacturer: Toshiba (0x031)
Part(0): TMPA9xx (0x7926)
Stepping: 0
Filename: /home/uwe/ur/share/urjtag/toshiba/tmpa9xx/tmpa9xx
I haven't tested more than "detect", but the info in the tmpa9xx file
is all correct as per datasheets of the various TMPA90x/91x devices.
Uwe.
