It is useful to be able to keep track of the available CPUs in a multi-CPU system. This uclass is mostly intended for use with SMP systems. The uclass provides methods for getting basic information about each CPU. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

This allows drivers to be provided for CPUs and their type to be
|
|
specified in the board's device tree. For boards which support
|
|
multiple CPUs, then normally have to be set up in U-Boot so that
|
|
they can work correctly in the OS. This provides a framework for
|
|
finding out information about available CPUs and making changes.
