* smp: Add APIC finder and parserAlmudena Garcia2020-09-191-0/+543
To find the processors, It's necessary to find the APIC (MADT) table This table is found inside ACPI tables. This set of functions find the MADT table, and parse it to find the APIC structures and register it in the kernel. *acpi_parse_apic.h: ACPI structures and function prototypes. *acpi_parse_apic.c: ACPI/APIC function definitions.
