Yes, the mail is valid, and I'm busy as usual.
Now, this STA2X11 is a chipset by ST-Ericcson that was bringing the
AMBA peripherals to the PC world. It was meant to be used as an I/O
device in the automotive sector, as far as I know (the audio part had
features aimed at automotive installations). I'm sure the chip was
never used in standard PC's -- the eval board was a PCIe slot, but
that's it.
So, I can't test and I don't know if there are users of this chip.
If there are users, they are big numbers. I think we can accept any
clean-up patch on the code base: if anything goes wrong, the users
will surface with a fix when they'll consider an upgrade to their
installed systems.
