[MIPS] remove Documentation/mips/GT64120.README
Based upon the 2.4 kernel, the information presented in the Documentation/mips/GT64120.README file is outdated. Worse, the document contents are plain misleading nowadays because the text mentions files and directories, which have been deleted, moved or restructured for 2.6. This patch removes the documentation, which is no more valid. Signed-off-by: Dmitri Vorobiev <dmitri.vorobiev@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

6MOTIVATION
7----------
8
9Many MIPS boards share the same system controller (or CPU companian chip),
10such as GT-64120. It is highly desirable to let these boards share
11the same controller code instead of duplicating them.
12
13This directory is meant to hold all MIPS boards that use GT-64120 or GT-64120A.
14
15
16HOW TO ADD A BOARD
17------------------
18
19. Create a subdirectory include/asm/gt64120/<board>.
20
21. Create a file called gt64120_dep.h under that directory.
22
23. Modify include/asm/gt64120/gt64120.h file to include the new gt64120_dep.h
24 based on config options. The board-dep section is at the end of
25 include/asm/gt64120/gt64120.h file. There you can find all required
26 definitions include/asm/gt64120/<board>/gt64120_dep.h file must supply.
27
28. Create a subdirectory arch/mips/gt64120/<board> directory to hold
29 board specific routines.
30
31. The GT-64120 common code is supplied under arch/mips/gt64120/common directory.
32 It includes:
33 1) arch/mips/gt64120/pci.c -
34 common PCI routine, include the top-level pcibios_init()
35 2) arch/mips/gt64120/irq.c -
36 common IRQ routine, include the top-level do_IRQ()
37 [This part really belongs to arch/mips/kernel. jsun]
38 3) arch/mips/gt64120/gt_irq.c -
39 common IRQ routines for GT-64120 chip. Currently it only handles
40 the timer interrupt.
41
42. Board-specific routines are supplied under arch/mips/gt64120/<board> dir.
43 1) arch/mips/gt64120/<board>/pci.c - it provides bus fixup routine
44 2) arch/mips/gt64120/<board>/irq.c - it provides enable/disable irqs
45 and board irq setup routine (irq_setup)
46 3) arch/mips/gt64120/<board>/int-handler.S -
47 The first-level interrupt dispatching routine.
48 4) a bunch of other "normal" stuff (setup, prom, dbg_io, reset, etc)
49
50. Follow other "normal" procedure to modify configuration files, etc.
51
52
53TO-DO LIST
54----------
55
56. Expand arch/mips/gt64120/gt_irq.c to handle all GT-64120 interrupts.
57 We probably need to introduce GT_IRQ_BASE in board-dep header file,
58 which is used the starting irq_nr for all GT irqs.
59
60 A function, gt64120_handle_irq(), will be added so that the first-level
61 irq dispatcher will call this function if it detects an interrupt
62 from GT-64120.
63
64. More support for GT-64120 PCI features (2nd PCI bus, perhaps)
