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

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

x86: Move i8254_init() to x86_cpu_init_f()

2015-12-09T09:44:44Z

Right now i8254_init() is called from timer_init() in the tsc timer driver. But actually i8254 and tsc are completely different things. Since tsc timer has been converted to driver model, we should find a new place that is appropriate for U-Boot to call i8254_init(), which is now x86_cpu_init_f().

x86: Remove MIN_PORT80_KCLOCKS_DELAY

2015-12-01T13:23:51Z

This is not referenced anywhere. Remove it, as well as tsc_base_kclocks and tsc_prev in the global data. Signed-off-by: Bin Meng Acked-by: Simon Glass Fix 'Reomve' typo: Signed-off-by: Simon Glass

x86: Initialize GDT entry 1 to be the 32-bit CS as well

2015-10-21T13:46:25Z

Some OS (like VxWorks) requires GDT entry 1 to be the 32-bit CS. Signed-off-by: Bin Meng Acked-by: Simon Glass Tested-by: Jian Luo

x86: Switch to using generic global_data setup

2015-08-14T15:50:10Z

There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope. Signed-off-by: Simon Glass Reviewed-by: Bin Meng
