IRQ_CONNECT_STATIC() macro provides static interrupt registration. It creates an entry for _sw_isr_table, table of interrupt handlers. IRQ_CONFIG() macro provides interrupt controller configuration. On ARM platform it configures the priority of each interrupt. _sw_isr_table is implemented the way that each of it's elements is located in individual section. Sections are marked a "linkonce", thus when a device driver declares an interrupt handler, it overwrites the default _sw_isr_table entry.
