x86: Move the i386 code into its own directory

2017-02-06T03:38:46+00:00

Much of the cpu and interrupt code cannot be compiled on 64-bit x86. Move it
into its own directory and build it only in 32-bit mode.

x86: Correct address casts in interrupt code

2016-10-11T03:55:33+00:00

We should cast an address to unsigned long, not u32.

Let's configure LAPIC in a common place - interrupt_init().

dm: Use uclass_first_device_err() where it is useful

Use this new function in places where it simplifies the code.

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

2016-01-24T04:07:18+00:00

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

2015-11-13T14:46:18+00:00

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).

x86: Show the un-relocated IP address in exceptions

2015-08-14T15:50:12+00:00

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.

x86: Handle running as EFI payload

2015-08-05T14:44:08+00:00

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.

x86: Add support for U-Boot as an EFI application

2015-08-05T14:44:06+00:00

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.
