jtagspi driver with support for 4-byte addresses (needed for large Flash Memories)

[SteffenKlu]

The jtagspi driver was updated this month (https://review.openocd.org/c/openocd/+/4876/) and I am interested if
you could build a new 'xpack-openocd-0.11.xx' Tar-ball which includes those latest improvements?
I tried to flash the large SPI-Flash in an Xilinx-Board, with the existing openocd release but it failed:

I hope the new enhancements to the jtagspi driver solve this problem.

Best,

I added a new issue (#16), to keep track of this request.

I'll do it, but It'll probably take more than a week, I'm upgrading all build scripts to support Apple Silicon, and I have some more details to fix before being able to make new releases.
