Simon Glass	f07e58b878	cpu: Convert the methods to use a const udevice * ... These functions should not modify the device. Convert them to const so that callers don't need to cast if they have a const udevice *. Signed-off-by: Simon Glass <sjg@chromium.org>	2020-07-20 11:37:47 -06:00
Wolfgang Wallner	2c64d11e32	x86: apl: Use cpu_x86_get_count() for cpu_ops.get_count ... Use cpu_x86_get_count() to read the number of cores. cpu_x86_get_count() reads the number of CPUs from the device tree. Using this function we can support multiple Apollo Lake variants, e.g.: E3940 (4 cores) and E3930 (2 cores). This was tested on the E3940 and E3930 Apollo Lake variants.
