2015-04-30x86: Allow CPUs to be set up after relocationSimon Glass
This permits init of additional CPU cores after relocation and when driver model is ready. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-04-29x86: Add an mfence macroSimon Glass
Provide access to this x86 instruction from C code. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2014-11-21x86: Replace fill_processor_name() with cpu_get_name()Simon Glass
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>
2014-11-21x86: Do CPU identification in the early phaseBin Meng
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>
2014-10-28x86: Add support for starting 64-bit kernelSimon Glass
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>
2014-10-28x86: Display basic CPU information on bootSimon Glass
Display the type of CPU (x86 or x86_64) when starting up. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-10-28x86: Move paging functions into cpu.cSimon Glass
These functions really don't belong in physmem as they relate to the cpu. Move them. Signed-off-by: Simon Glass <sjg@chromium.org>
