Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+
+STEPS TO BUILD DRIVER
+================================================================================
+
+ 1. Backup the Config.in and Makefile in the sound driver directory
+ (/usr/src/linux/driver/sound).
+ The Configure.help provide help when you config driver in step
+ 4, please backup the original one (/usr/src/linux/Document) and
+ copy this file.
+ The cmpci is document for the driver in detail, please copy it
+ to /usr/src/linux/Document/sound so you can refer it. Backup if
+ there is already one.
+
+ 2. Extract the tar file by 'tar xvzf cmpci-xx.tar.gz' in the above
+ directory.
+
+ 3. Change directory to /usr/src/linux
+
+ 4. Config cm8338 driver by 'make menuconfig', 'make config' or
+ 'make xconfig' command.
+
+ 5. Please select Sound Card (CONFIG_SOUND=m) support and CMPCI
+ driver (CONFIG_SOUND_CMPCI=m) as modules. Resident mode not tested.
+ For driver option, please refer 'DRIVER PARAMETER'
+
+ 6. Compile the kernel if necessary.
+
+ 7. Compile the modules by 'make modules'.
+
+ 8. Install the modules by 'make modules_install'
+
+
+INSTALL DRIVER
+================================================================================
+
+ 1. Before first time to run the driver, create module dependency by
+ 'depmod -a'
+
+ 2. To install the driver manually, enter 'modprobe cmpci'.
+
+ 3. Driver installation for various distributions:
+
+ a. Slackware 4.0
+ Add the 'modprobe cmpci' command in your /etc/rc.d/rc.modules
+ file.so you can start the driver automatically each time booting.
+
+ b. Caldera OpenLinux 2.2
+ Use LISA to load the cmpci module.
+
+ c. RedHat 6.0 and S.u.S.E. 6.1
+ Add following command in /etc/conf.modules:
+
+ alias sound cmpci
+
+ also visit http://www.cmedia.com.tw for installation instruction.
