* x86: Replace fill_processor_name() with cpu_get_name()Simon Glass2014-11-21-3/+8
| | | | | | | | This implementation has a 'cpu' prefix and returns a pointer to the string, avoiding the need for copying. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Do CPU identification in the early phaseBin Meng2014-11-21-4/+164
| | | | | | | The CPU identification happens in x86_cpu_init_f() and corresponding fields are saved in the global data for later use. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Add support for starting 64-bit kernelSimon Glass2014-10-28-0/+26
| | | | | | | | Add code to jump to a 64-bit Linux kernel. We need to set up a flat page table structure, a new GDT and then go through a few hoops in the right order. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Display basic CPU information on bootSimon Glass2014-10-28-0/+7
| | | | | | Display the type of CPU (x86 or x86_64) when starting up. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Move paging functions into cpu.cSimon Glass2014-10-28-0/+22
These functions really don't belong in physmem as they relate to the cpu. Move them. Signed-off-by: Simon Glass <sjg@chromium.org>
