- *
- * 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 unnecessary 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).
