x86: Add GDT descriptors for option ROMs

2014-11-25T13:34:14Z

Option ROMs require a few additional descriptors. Add these, and remove the enum since we now have to access several descriptors from assembler. Signed-off-by: Simon Glass

x86: Remove cpu_init_r() for x86

2014-11-25T13:34:02Z

Since cpu_init_interrupts() was moved out of cpu_init_r(), it is useless to keep cpu_init_r() for x86, thus remove it. Signed-off-by: Bin Meng Acked-by: Simon Glass Tested-by: Simon Glass

x86: Call cpu_init_interrupts() from interrupt_init()

2014-11-25T13:34:02Z

Currently cpu_init_interrupts() is called from cpu_init_r() to setup the interrupt and exception of the cpu core, but at that time the i8259 has not been initialized to mask all the irqs and remap the master i8259 interrupt vector base, so the whole system is at risk of being interrupted, and if interrupted, wrong interrupt/exception message is shown.

x86: Make show_boot_progress() common

2014-11-21T06:34:15Z

This function can probably be used on all x86 boards, so move it into the common file. Signed-off-by: Simon Glass

x86: Replace fill_processor_name() with cpu_get_name()

2014-11-21T06:24:12Z

This implementation has a 'cpu' prefix and returns a pointer to the string, avoiding the need for copying. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Fix a warning with gcc 4.4.4

2014-11-21T06:24:10Z

This warning appears even though it seems that the compiler could work it out. Fix it. Signed-off-by: Simon Glass

x86: Do CPU identification in the early phase

2014-11-21T06:24:10Z

The CPU identification happens in x86_cpu_init_f() and corresponding fields are saved in the global data for later use. Signed-off-by: Bin Meng

x86: Fix up some missing prototypes

2014-11-21T06:24:09Z

Some functions are missing prototypes. Fix those that are specific to x86. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Use the standard arch_cpu_init() function

2014-11-21T06:24:09Z

Instead of an x86-specific cpu_init_f() function, use the normal U-Boot one for this purpose. Also remove a useless/misleading comment. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Add support for starting 64-bit kernel

2014-10-29T02:43:47Z

Add code to jump to a 64-bit Linux kernel. We need to set up a flat page table structure, a new GDT and then go through a few hoops in the right order. Signed-off-by: Simon Glass
