wireless kernel driver porting

wireless kernel driver porting

[nahidesafe-kernel]

Hi all, I've bought a USB wireless TA bundled with GPL
Linux drivers for 2.6.11 kernel series.
The driver seems to compile fine with 2.6.15-gentoo-r1
on x86, but can't be used on x86_64 systems.
Technical support can't provide a porting of the
driver in the short time.
It seems that there are no driver included in the
current kernel tree for this wireless TA:
Conitech Dakota Wireless TA 56Mbps.
The driver provided is the IS89C35 Wireless Linux
Driver 3.0.47.0, copyrighted by  Winbond Electronic
Corporation, ISSC and released with
MODULE_LICENSE("GPL");

I haven't a ftp server where to put the driver tarball
so if you can help me tell me where I can send an
email with the driver as attachment ~500kb.
Please CC me in your reply, I'm not subscribed to the
list.

Hi. Maybe I can help u providing some http space. I also bought "Conitech Dakota
Wireless TA 56Mbps" but drivers are currently not working: my version is
"hal_059"...

Adding support for IDE on nCS5 on an ARM7

[Sam]

	I'm working on getting the IDE subsystem to communicate with an IDE device wired to nCS5 on a CLEP7312 board.  I have
0x50000000 set to be remapped to 0xfe100000 but whenever I try to access the registers I get kernel crashes.  I'm sure I'm doing
something wrong, since this works on a 2.6 kernel... but I don't know where to find what I'm doing wrong.

Could somebody perhaps let me know if they know what I'm doing wrong, or point me in the right direction of the relevant
documentation?

The error below is from trying to access as 32-bit wide blocks, same thing happens if I try to read it as an 8-bit block...

It also does the same thing if I don't do the mapping and try to access at the physical base address... but of course I shouldn't be
doing that anyways right?

Thanks,
Sam
