Linux-2.6.12-rc2

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!

+ * The following devices are accessable using this driver using
+ * GPIO_MAJOR (120) and a couple of minor numbers:
+ * For ETRAX 100LX (ARCH_V10):
+ * /dev/gpioa  minor 0, 8 bit GPIO, each bit can change direction
+ * /dev/gpiob  minor 1, 8 bit GPIO, each bit can change direction
+ * /dev/leds   minor 2, Access to leds depending on kernelconfig
+ * /dev/gpiog  minor 3
+         g0dir, g8_15dir, g16_23dir, g24 dir configurable in R_GEN_CONFIG
+         g1-g7 and g25-g31 is both input and outputs but on different pins
+         Also note that some bits change pins depending on what interfaces 
+         are enabled.
+ *
+ *
+ * For ETRAX 200 (ARCH_V32):
+ * /dev/gpioa  minor 0,  8 bit GPIO, each bit can change direction
+ * /dev/gpiob  minor 1, 18 bit GPIO, each bit can change direction
+ * /dev/gpioc  minor 2, 18 bit GPIO, each bit can change direction
+ * /dev/gpiod  minor 3, 18 bit GPIO, each bit can change direction
+ * /dev/gpioe  minor 4, 18 bit GPIO, each bit can change direction
+ * /dev/leds   minor 5, Access to leds depending on kernelconfig
