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

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree onlyAll drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.Note this involves changing some dead code - the imx_lpi2c.c file.

As far as I know BCM3380 has a fixed CPU frequency since I couldn't find its
PLL registers in any documentation.Signed-off-by: Álvaro Fernández Rojas

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.Signed-off-by: Alexander Graf

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.Signed-off-by: Bin 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

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

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.
