Sorry, there are lot of patches, and most of them have coding styles.
Becuase the entire open source release (I mean 'mine' open source release)
was
initialated 2 weeks ago.
And yes, you might have noticed. The QEMU is my very 1st open source
release....
And there are somehing make things even worst ....
For example:
In u-boot, there are already some bad code / or heavily un-tested code
have release to its git tree.
i.e.
1. The ftsdc010_esdhc contributed by Andes Technology (a subsidiary of
Faraday)
simply doesn't work at Faraday A369 in u-boot-2013.01.
One of my colleague has ever make it work in u-boot-2010.09,
but its performanceis only 1/10 of mine ...
2. The ftgmac100 is somehow contributed by someone should do that with a
untested version, although it seemds to work correctly with MMU
disabled.
All of these, means after applying my patch, you would have multi-pile
drivers
against the same hardware....
If none of these were problem to you, I'll tried to make them open source
later.
And for a record, in my original open source schedule, the following items
would be release in turn.
1) qemu (a36x)
2) u-boot-2013.01
3) linux-3.4.12
4) falinux (It's a combination of uClinux and build-root, was my personal
linux BSP, and now seems to be an official one in Faraday)
5) android-4.0.4
6) linux-3.0.31 for android
7) android-dist (A clone of falinux, which is designed to genrated andoird
images)
8) contiki-2.6
9) contiki-2.6-dist (A clone of falinux, which is designed to genrated
contiki images)
10) ecos-3.0
11) ecos-dist (A clone of falinux, which is designed to genrated contiki
images)
12) virgil (A referenced ROM code for my projects, which is also a
RTOS/FreeRTOS)
Because Faraday is actually a ASIC desgin service company, it usualy cares
nothing
about software and intends to make them all open sourced to catch more
customers.

Sorry, I can't get you very well...
I guess I'm not supposed to use --in-reply-to=<identifier> with git
send-email
and change log should not be removed.
Any way I'll try to find some examples from the email and google for some
more to see how to do that....

Sorry, IRC is banned from my company, and I usually don't work at home....
My wife would get crazzy on me.
P.S:
My real work is to help customers to build new their own new SoC platform
and it's extremely easy so I usually have lots of private time at work.
