2017-06-01dm: core: Update device_bind_driver_to_node() to use ofnodeSimon Glass
Adjust this function to us an ofnode instead of an offset, so it can be used with livetree. This involves updating all callers. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-10-19cpu: Add get_vendor callbackAlexander Graf
The CPU udevice already has a few callbacks to retreive information about the currently running CPUs. This patch adds a new get_vendor() call that returns the vendor of the main CPUs.

2015-07-15x86: Move MP initialization codes into a common placeBin Meng
Most of the MP initialization codes in arch/x86/cpu/baytrail/cpu.c is common to all x86 processors, except detect_num_cpus() which varies from cpu to cpu. Move these to arch/x86/cpu/cpu.c and implement the new 'get_count' method for baytrail and cpu_x86 drivers. Now we call cpu_get_count() in mp_init() to get the number of CPUs.

2015-07-15dm: cpu: Add a new get_count method to cpu uclassBin Meng
Introduce a new method 'get_count' in the UCLASS_CPU ops to get the number of CPUs in the system. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
2015-07-15dm: cpu: Test against cpu_ops->get_info in cpu_get_info()Bin Meng
In cpu_get_info() it wrongly tests against cpu_ops->get_desc to see if it is NULL. It should test against cpu_ops->get_info. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>

2015-04-30dm: Implement a CPU uclassSimon Glass
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>
