Kernel support for QNAP TS-119 and TS-219 Turbo NAS in 2.6.30

<p>

My patch for initial kernel support for the QNAP TS-119 and TS-219
Turbo NAS got accepted and will be in 2.6.30.  I can run Debian on
a USB disk without any problems but there are some issues left (some
severe, some cosmetic):

</p>

<ul>

<li>SATA: there are long timeouts when initializing the disk.  In most
cases, the disk is eventually recognized but it can take quite some time.
I've no idea why those timeouts happen.</li>

<li>Flash: I can read from flash just fine but writing doesn't work.</li>

<li>Parsing the MAC address: even though a MAC address is set in u-boot,
the QNAP firmware stores the real MAC address in flash (similar to the
TS-109 and TS-209).  The TS-109/TS-209 code to read the MAC address doesn't
work because the flash on the TS-219 is connected in a different way
(SPI).</li>

<li>SATA lights: the activity light doesn't work.</li>

</ul>

<p>

Unfortunately, I've no idea how to resolve these issues.  However, the QNAP
TS-119 and TS-219 have started shipping so hopefully someone else will
investigate these issues.
