* x86: Drop old CONFIG_INTEL_CORE_ARCH codeSimon Glass2014-11-25-28/+0
| | | | | | | This is no-longer used, so drop it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* x86: Refactor interrupt_init()Bin Meng2014-11-25-6/+20
| | | | | | | | | | | Rename interrupt_init() in arch/x86/lib/pcat_interrupts.c to i8259_init() and create a new interrupt_init() in arch/x86/cpu/interrupt.c to call i8259_init() followed by a call to cpu_init_interrupts().

* x86: Fix up some missing prototypesSimon Glass2014-11-21-1/+1
| | | | | | | Some functions are missing prototypes. Fix those that are specific to x86. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* x86: Declare global_data pointer when it is usedSimon Glass2013-05-13-0/+2
| | | | | | | | Several files use the global_data pointer without declaring it. This works because the declaration is currently a NOP. But still it is better to fix this so that x86 lines up with other archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Permit bootstage and timer data to be used prior to relocationSimon Glass2013-03-04-4/+3
| | | | | | | | | It is useful to be able to access the timer before U-Boot has relocated so that we can fully support bootstage. Add new global_data members to support this. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Provide tick counter and frequency reference for Intel core architectureVadim Bendebury2012-12-06-0/+31
| | | | | | | | | | | | | | | Some u-boot modules rely on availability of get_ticks() and get_tbclk() functions, reporting a free running clock and its frequency respectively. Traditionally these functions return number and frequency of timer interrupts. Intel's core architecture processors however are known to run the rdtsc instruction at a constant rate of the so called 'Max Non Turbo ratio' times the external clock frequency which is 100MHz. This is just as good for the timer tick functions in question. Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>

* Convert ISO-8859 files to UTF-8Albert ARIBAUD2011-08-04-2/+2
| | | | | | | | There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
