The Cortex-M related Kconfig menus and options no longer show up at the top level when "make ARCH=arm menuconfig" is issued. They show up under the "General Platform Configuration" menu. Change-Id: I6bf012e628212340f5e089d0193a9a71d90c79b9 Signed-off-by: Peter Mitsis <peter.mitsis@windriver.com>

Thumb-2 technology is the instruction set underlying the ARM Cortex
|
|
architecture which provides enhanced levels of performance, energy
|
|
efficiency, and code density for a wide range of embedded
|
|
applications.
|
|
|
|
Thumb-2 technology builds on the success of Thumb, the innovative
|
|
high code density instruction set for ARM microprocessor cores, to
|
|
increase the power of the ARM microprocessor core available to
|
|
developers of low cost, high performance systems.
|
|
|
|
The technology is backwards compatible with existing ARM and Thumb
|
|
solutions, while significantly extending the features available to
|
|
the Thumb instructions set. This allows more of the application to
|
|
benefit from the best in class code density of Thumb.
|
|
|
|
For performance optimised code Thumb-2 technology uses 31 percent
|
|
less memory to reduce system cost, while providing up to 38 percent
|
|
higher performance than existing high density code, which can be used
|
|
to prolong battery-life or to enrich the product feature set. Thumb-2
|
|
technology is featured in the processor, and in all ARMv7
|
|
architecture-based processors.
