x86: Move the i386 code into its own directory

2017-02-06T03:38:46Z

Much of the cpu and interrupt code cannot be compiled on 64-bit x86. Move it into its own directory and build it only in 32-bit mode. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Correct address casts in cpu code

2016-10-11T03:55:33Z

We should cast an address to unsigned long, not u32. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Probe pinctrl driver in cpu_init_r()

2016-06-12T04:19:35Z

At present pinctrl driver gets probed in ich6_gpio driver's probe routine, which has two issues: - Pin's PADs only gets configured when GPIO driver is probed, which is not done by default. This leaves the board in a partially functional state as we must initialize PADs correctly to get perepherals fully working. - The probe routine of pinctrl driver is called multiple times, as normally there are multiple GPIO controllers. It should really be called just once. Move the call to syscon_get_by_driver_data() from ich6_gpio driver to cpu_init_r().

x86: Reserve configuration tables in high memory

When SeaBIOS is on, reserve configuration tables in reserve_arch(). Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: Unify reserve_arch() for all x86 boards

2016-05-23T07:18:00Z

Instead of asking each platform to provide reserve_arch(), supply it in arch/x86/cpu/cpu.c in a unified way. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: Call board_final_cleanup() in last_stage_init()

2016-05-23T07:18:00Z

At present board_final_cleanup() is called before booting a Linux kernel. This actually needs to be done before booting anything, like SeaBIOS, VxWorks or Windows. Move the call to last_stage_init() instead. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

x86: Update microcode for secondary CPUs

2016-03-17T02:27:25Z

Each CPU needs to have its microcode loaded. Add support for this so that all CPUs will have the same version. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Rename PORT_RESET to IO_PORT_RESET

2016-03-17T02:27:24Z

This same name is used in USB. Add a prefix to distinguish it. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: cpu: Add functions to return the family and stepping

2016-03-17T02:27:24Z

These two identifiers can be useful for drivers which need to adjust their behaviour depending on the CPU family or stepping (revision). Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: cpu: Make the vendor table const

2016-03-17T02:27:23Z

This does not need to be modified at run-time, so make it const. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
