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!

+Module options
+--------------
+
+The mwave module takes the following options. Note that these options
+are not saved by the BIOS and so do not persist after unload and reload.
+
+ mwave_debug=value, where value is bitwise OR of trace flags:
+ 0x0001 mwavedd api tracing
+ 0x0002 smapi api tracing
+ 0x0004 3780i tracing
+ 0x0008 tp3780i tracing
+
+ Tracing only occurs if the driver has been compiled with the
+ MW_TRACE macro #defined (i.e. let EXTRA_CFLAGS += -DMW_TRACE
+ in the Makefile).
+
+ mwave_3780i_irq=5/7/10/11/15
+ If the dsp irq has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ irq used by the dsp to be configured.
+
+ mwave_3780i_io=0x130/0x350/0x0070/0xDB0
+ If the dsp io range has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ io range used by the dsp to be configured.
+
+ mwave_uart_irq=3/4
+ If the mwave's uart irq has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ irq used by the mwave uart to be configured.
+
+ mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
+ If the uart io range has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ io range used by the mwave uart to be configured.
+
+Example to enable the 3780i DSP using ttyS1 resources:
+
+ insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
+
+Accessing the driver
+--------------------
+
+You must also create a node for the driver. Without devfs:
+ mkdir -p /dev/modems
+ mknod --mode=660 /dev/modems/mwave c 10 219
+With devfs:
+ mkdir -p /dev/modems
+ ln -s ../misc/mwave /dev/modems/mwave
+
