Hi Pierre:
People are quite used to reading diffs, so it's not that much of a bothe
I made a typo last time. we should say, we are NOT submitting patches;
instead, we are submitting original sources for Winbond 518/528/528DA
MS/MSPRO/xD/SM/SD/MMC sources.
Can we pack our sources then send them in one large attachment?
Uncompressed attachments, or inline inclusions, are usually preferred as
it allows you to read the stuff in your mail application.
I think we will do the inline inclusion for it's easier for everybody to
read.
I have one reservation with your driver though. The Linux kernel already
has a generic SD/MMC layer. So if your hardware is a bus interface, then
it should use that layer. There is even a driver there for your
W83L518/9 devices. :)
Hmm, we might take this suggestion into consideration later. Right
now, we would like to keep our current architecture for internal
maintenance issues. The first thing we would like to do now is
contributing our 518/528/528DA MS/MSPRO/xD/SM/SD/MMC and smart card
drivers into Linux kernel source tree. There are, of course, many things
can be improved in our codes. But at least we have run stree testing on
many platforms from Intel 32/64 AMD 32/64 and single/dual
configurations. We would like to contribute to kernel first then we can
still update/modify/improve them later. Is that OK?
For the other buses, a generic layer would be preferable, but as you
would be the only user, that isn't required quite yet. I would suggest
contacting Andrew Morton as he is the overall 2.6 maintainer.
yes, and his email? thank you.
PS. I have a question regarding the W83L518 hardware, but haven't been
able to get in touch with the right people. Perhaps you have some pointers?
anything about Winbond 518/528/528DA drivers, send email to
[email protected] which is ME.....
dz
ps. did you get my email from linux-kernel? It seems like my emails to
linux-kernel with my attachments are gone for no reason. Will that be my
email size is over 100k?
