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: 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

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

x86: Bring up northbridge, pch and lpc after the CPUs

2016-01-24T04:08:17Z

These devices currently need to be inited early in boot. Once we have the init in the right places (with each device doing its own init and no problems with ordering) we should be able to remove this. For now it is needed to keep things working. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Make x86_init_cpus() static

2016-01-24T04:08:17Z

There are no other implementations of this function, and boards that need it can implement a CPU driver. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
