-README for arch/mips/gt64120 directory and subdirectories
-
-Jun Sun, jsun@mvista.com or jsun@junsun.net
-01/27, 2001
-
-MOTIVATION
-----------
-
-Many MIPS boards share the same system controller (or CPU companian chip),
-such as GT-64120.  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/<board>.  
-
-. 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. There you can find all required
-  definitions include/asm/gt64120/<board>/gt64120_dep.h file must supply.
-
-. Create a subdirectory arch/mips/gt64120/<board> directory to hold
-  board specific routines.
-
-. 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.  Currently it only handles
-	 	the timer interrupt.
-
-. Board-specific routines are supplied under arch/mips/gt64120/<board> dir.
-	1) arch/mips/gt64120/<board>/pci.c - it provides bus fixup routine
-	2) arch/mips/gt64120/<board>/irq.c - it provides enable/disable irqs
-		and board irq setup routine (irq_setup)
-	3) arch/mips/gt64120/<board>/int-handler.S -
-		The first-level interrupt dispatching routine.
-	4) a bunch of other "normal" stuff (setup, prom, dbg_io, reset, etc)
-
-. Follow other "normal" procedure to modify configuration files, etc.
-
-
-TO-DO LIST
-----------
-
-. 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)
