@cshilwant No, we should not remove the fle, we will be adding SW UART support here in the future, why remove it?

Ordinary we would remove files when they no longer have any references. I do not see any reason for this to be special. It's git. We can always revert.

PRU SW UART is currently not supported, remove from TOC and
remove rst file since it is no longer used.

PRU HW UART support exists for AM62x and AM64x SK board, enable
documentation for these platforms and update rst to accommodate
the new platforms.

Fix a few other misc issues while we are here, including whitespace,
mispelling, and missing inline role issues.
