OpenOCD target for Telink chips (TLSR8266, etc.)

Hi,

I am trying to program a Telink chip TLSR8266 using OpenOCD.

Though I am missing a target for this type of chip; so I wanted to know if anyone has been successfully in flashing a Telink chip using OpenOCD?

And does anyone have a target file he/she could share with me for this type of chip?

Thanks
