[PATCH 1/1] Add manpage entry for pony_spi

[Virgil-Adrian Teaca]

Hello,

First of all, I want to note that the properly name of the native
Ponyprog2000 hardware programmer is "SI-Prog" and not "SI_Prog".

Also, talking about:

"Please note that while USB-to-serial adapters work under certain
circumstances, this slows down operation considerably."

Well, I for one, I understand by "considerably" that the operation will do
hours, instead of minutes. The sadly truth is that operation will be epic
slow. If I remember right,
that EEEPC's W25X40, which I flashed, is not a huge flash, just 4M. Still,
it was flashed in cca 27 hours.

Then, yes, PONY_SPI works fine over an PL2303 USB/serial adapter, under
Linux, but its job is epically slow...

So, I believe that is right to warn the user that he have to wait a very
very long time.

All the best,
Virgil.
