x86: Call lapic_setup() in interrupt_init()

2016-05-23T07:27:41Z

Let's configure LAPIC in a common place - interrupt_init(). Signed-off-by: Bin Meng Reviewed-by: Simon Glass

dm: Use uclass_first_device_err() where it is useful

2016-03-14T21:34:50Z

Use this new function in places where it simplifies the code. Signed-off-by: Simon Glass

dm: x86: Set up interrupt routing from interrupt_init()

2016-01-24T04:07:18Z

At present interrupt routing is set up from arch_misc_init(). We can do it a little later instead, in interrupt_init(). This removes the manual pirq_init() call. Where the platform does not have an interrupt router defined in its device tree, no error is generated. Some platforms do not have this. Drop pirq_init() since it is no-longer used.

x86: Rename pcat_ to i8254 and i8259 accordingly

2015-11-13T14:46:18Z

Rename pcat_timer.c to i8254.c and pcat_interrupts.c to i8259.c, to match their header file names (i8254.h and i8259.h). Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Show the un-relocated IP address in exceptions

2015-08-14T15:50:12Z

When trying to figure out where an exception has occured, the relocated address is not a lot of help. Its value depends on various factors. Show the un-relocated IP as well. This can be looked up in System.map directly. Signed-off-by: Simon Glass Reviewed-by: Tom Rini 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: Add support for U-Boot as an EFI application

2015-08-05T14:44:06Z

Add the required x86 glue code. This includes the initial start-up, relocation and jumping to efi_main(). We also need to avoid fiddling with interrupts. Signed-off-by: Ben Stoltz Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Tidy up a few minor issues with interrupts

2015-08-05T14:42:41Z

Fix a typo, remove an unused field and make sure to use existing #define constants instead of open-coded values. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Simplify architecture defined exception handling in irq_llsr()

2015-07-28T16:36:21Z

Instead of using switch..case for architecture defined exceptions, simply unify the handling by printing a message of exception name, followed by registers dump then halt the CPU. With this unification, it also fixes the wrong exception numbers for #MF/#AC/#MC/#XM which should be 16/17/18/19 not 15/16/17/18. Signed-off-by: Bin Meng Acked-by: Simon Glass

x86: Display correct CS/EIP/EFLAGS when there is an error code

2015-07-28T16:36:21Z

Some exceptions cause an error code to be saved on the current stack after the EIP value. We should extract CS/EIP/EFLAGS from different position on the stack based on the exception number. Signed-off-by: Bin Meng Acked-by: Simon Glass
