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

x86: Move the GDT into global_data

2015-08-14T15:50:10Z

Rather than keeping track of the Global Descriptor Table in its own memory we may as well put it in global_data with everything else. As a first step, stop using the separately allocated GDT. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Handle running as EFI payload

2015-08-05T14:44:08Z

When U-Boot runs as an EFI payload it needs to avoid setting up the CPU again. Also U-Boot currently does not handle interrupts for many devices, so run with interrupts disabled. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Use CR0 constants in CPU init

2015-08-05T14:42:40Z

We should use these constants where possible. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Allow cpu-x86 driver to be probed for UP

2015-07-28T16:36:25Z

Currently cpu-x86 driver is probed only for SMP. We add the same support for UP when there is only one cpu node in the deive tree. Signed-off-by: Bin Meng Acked-by: Simon Glass
