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!

+ *
+ * Theory of operations
+ * ====================
+ * 
+ * Clock scaling can be used to lower the power consumption of the CPU
+ * core. This will give you a somewhat longer running time.
+ *
+ * The SA-1100 has a single register to change the core clock speed:
+ *
+ *   PPCR      0x90020014    PLL config
+ *
+ * However, the DRAM timings are closely related to the core clock
+ * speed, so we need to change these, too. The used registers are:
+ *
+ *   MDCNFG    0xA0000000    DRAM config
+ *   MDCAS0    0xA0000004    Access waveform
+ *   MDCAS1    0xA0000008    Access waveform
+ *   MDCAS2    0xA000000C    Access waveform 
+ *
+ * Care must be taken to change the DRAM parameters the correct way,
+ * because otherwise the DRAM becomes unusable and the kernel will
+ * crash. 
+ *
+ * The simple solution to avoid a kernel crash is to put the actual
+ * clock change in ROM and jump to that code from the kernel. The main
+ * disadvantage is that the ROM has to be modified, which is not
+ * possible on all SA-1100 platforms. Another disadvantage is that
+ * jumping to ROM makes clock switching unecessary complicated.
+ *
+ * The idea behind this driver is that the memory configuration can be
+ * changed while running from DRAM (even with interrupts turned on!)
+ * as long as all re-configuration steps yield a valid DRAM
+ * configuration. The advantages are clear: it will run on all SA-1100
+ * platforms, and the code is very simple.
+ * 
+ * If you really want to understand what is going on in
+ * sa1100_update_dram_timings(), you'll have to read sections 8.2,
+ * 9.5.7.3, and 10.2 from the "Intel StrongARM SA-1100 Microprocessor
+ * Developers Manual" (available for free from Intel).
