[U-Boot] [PATCH v2 11/28] x86: acpi: Remove unused codes

- Remove #include <> header files. - Remove APM_CNT register defines, which should not be here as they are SMI related. - Remove MP_IRQ_ defines as they are duplicates of the same ones in asm/mpspec.h. - Remove ACTL register defines, which should not be here as they are chipset specific. -

[U-Boot] [PATCH v2 15/28] x86: acpi: Change fill_header()

Rename fill_header() to acpi_fill_header() for consistency. Change its signature to remove the 'length' parameter and make it a public API. Also remove the unnecessary include files, and improve the AmlCode[] comment a little bit. Signed-off-by: Bin Meng Reviewed-by: Stefan

[U-Boot] [PATCH v2 09/28] acpi: Specify U-Boot include path for ASL files

[U-Boot] [PATCH v2 08/28] acpi: Explicitly spell out dsdt.c in the make rule

Currently the make rule for dsdt.c uses a wildcard, as below: $(obj)/%.c:$(src)/%.asl To avoid any side effect, explicitly mention dsdt.c as this is the file we intend to use for ACPI DSDT AML generation. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese

[U-Boot] [PATCH v2 05/28] x86: irq: Enable SCI on IRQ9

By default SCI is disabled after power on. ACTL is the register to enable SCI and route it to PIC/APIC. To support both ACPI in PIC mode and APIC mode, configure SCI to use IRQ9. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese Tested-by: Stefan Roese

[U-Boot] [PATCH v2 07/28] acpi: Change build log for ASL files

Currently when compiling U-Boot with ASL file, the build log says: ASL board/intel/bayleybay/dsdt.c This looks odd as ASL compiler's input is ASL file, not C file. Change the make rule to use $< instead. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese
