- CPU clock scaling allows you to change the clock speed of the
- running CPU on the fly. This is a nice method to save battery power,
- because the lower the clock speed, the less power the CPU
- consumes. Note that this driver doesn't automatically change the CPU
- clock speed, you need some userland tools (which still have to be
- written) to implement the policy. If you don't understand what this
- is all about, it's safe to say 'N'.

+ bool "Kernel Execute-In-Place from ROM"
+ depends on !ZBOOT_ROM
+ help
+ Execute-In-Place allows the kernel to run from non-volatile storage
+ directly addressable by the CPU, such as NOR flash. This saves RAM
+ space since the text section of the kernel is not loaded from flash
+ to RAM. Read-write sections, such as the data section and stack,
+ are still copied to RAM. The XIP kernel is not compressed since
+ it has to run directly from flash, so it will take more space to
+ store it. The flash address used to link the kernel object files,
+ and for storing it, is configuration dependent. Therefore, if you
+ say Y here, you must know the proper physical address where to
+ store the kernel image depending on your own flash memory usage.
+
+ Also note that the make target becomes "make xipImage" rather than
+ "make zImage" or "make Image". The final kernel binary to put in
+ ROM memory will be arch/arm/boot/xipImage.

-# CPUfreq on SA11x0 is special -- it _needs_ the userspace governor
+ Please note that, if you're using MTD, you must use a flash chip
+ that is NOT handled by MTD or the flash will be turned into non
+ data mode for status and query purposes which will instantaneously
+ crash the kernel.
+
+ MTD can however be used with a XIP kernel on the same flash chip
+ but only if the flash memory supports multiple partitions in
+ hardware, like with the Intel K3 flash parts, and only if the
+ kernel is not stored within the firrst hardware partition of the
+ chip.
+
+ In any case, make sure that MTD support is configured out for
