Adding support for the Adva timecard.
The card uses different drivers to provide access to the
firmware SPI flash (Altera based).
Other parts of the code are the same and could be reused.

Hi Sagi,
Thanks for adjusting the code. One signle still have to be
adjusted, see comments below. And this is treated as net-next
material, but net-next is closed now until merge window ends,
you will have to submit new version next week.
Please, also use '[PATCH net-next v6] ...' prefix for it.

Please, use fw_tag = 3 here, other tags are for other vendors.

Hi Vadim,
Sorry but I was on vacation for the last two weeks.
So What should I do now:
1) Do you want me to set my changes into the main linux git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
and use use '[PATCH v6] ...' prefix
2) Or
set my changes into the net-next git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git
and use use '[PATCH net-next v6] ...' prefix
BR,
Sagi
