It is highly desirable to let these boards share -the same controller code instead of duplicating them. - -This directory is meant to hold all MIPS boards that use GT-64120 or GT-64120A. - - -HOW TO ADD A BOARD ------------------- - -. Create a subdirectory include/asm/gt64120/. - -. Create a file called gt64120_dep.h under that directory. - -. Modify include/asm/gt64120/gt64120.h file to include the new gt64120_dep.h - based on config options. The board-dep section is at the end of - include/asm/gt64120/gt64120.h file.

The GT-64120 common code is supplied under arch/mips/gt64120/common directory. - It includes: - 1) arch/mips/gt64120/pci.c - - common PCI routine, include the top-level pcibios_init() - 2) arch/mips/gt64120/irq.c - - common IRQ routine, include the top-level do_IRQ() - [This part really belongs to arch/mips/kernel. jsun] - 3) arch/mips/gt64120/gt_irq.c - - common IRQ routines for GT-64120 chip.

Board-specific routines are supplied under arch/mips/gt64120/ dir. - 1) arch/mips/gt64120//pci.c - it provides bus fixup routine - 2) arch/mips/gt64120//irq.c - it provides enable/disable irqs - and board irq setup routine (irq_setup) - 3) arch/mips/gt64120//int-handler.S - - The first-level interrupt dispatching routine. - 4) a bunch of other "normal" stuff (setup, prom, dbg_io, reset, etc) - -.

Expand arch/mips/gt64120/gt_irq.c to handle all GT-64120 interrupts. - We probably need to introduce GT_IRQ_BASE in board-dep header file, - which is used the starting irq_nr for all GT irqs. - - A function, gt64120_handle_irq(), will be added so that the first-level - irq dispatcher will call this function if it detects an interrupt - from GT-64120. - -. More support for GT-64120 PCI features (2nd PCI bus, perhaps) -
