* cpu: Add get_vendor callbackAlexander Graf2016-10-19-0/+1
| | | | | | | | | | 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.

* x86: baytrail: Add SIO HS-UART clock setupStefan Roese2016-08-16-0/+48
| | | | | | | | | | To support the BayTrail internal SIO HS UART, the internal UART clock needs to get configured. This patch adds support for this clock configuration which will be done, if the PCI device(s) are found.

* x86: baytrail: Support operation as an EFI payloadSimon Glass2015-08-05-0/+2
| | | | | | | | | Disable a few things which interfere with the EFI init. This allows the Minnowboard MAX to boot into EFI, load a U-Boot payload then boot to the U-Boot prompt. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Move MP initialization codes into a common placeBin Meng2015-07-14-69/+29
| | | | | | | | | | | 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.

* x86: dm: Clean up cpu driversBin Meng2015-07-14-12/+3
| | | | | | | | | | | | | | | This commit does the following to clean up x86 cpu dm drivers: - Move cpu_x86 driver codes from arch/x86/cpu/cpu.c to a dedicated file arch/x86/cpu/cpu_x86.c - Rename x86_cpu_get_desc() to cpu_x86_get_desc() to keep consistent naming with other dm drivers - Add a new cpu_x86_bind() in the cpu_x86 driver which does exactly the same as the one in the intel baytrail cpu driver - Update intel baytrail cpu driver to use cpu_x86_get_desc() and cpu_x86_bind() Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
* x86: Add a CPU driver for baytrailSimon Glass2015-04-30-0/+205
