1			Samsung ARM Linux Overview
2			==========================
3	
4	Introduction
5	------------
6	
7	  The Samsung range of ARM SoCs spans many similar devices, from the initial
8	  ARM9 through to the newest ARM cores. This document shows an overview of
9	  the current kernel support, how to use it and where to find the code
10	  that supports this.
11	
12	  The currently supported SoCs are:
13	
14	  - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
15	  - S3C64XX: S3C6400 and S3C6410
16	  - S5P6440
17	  - S5PC100
18	  - S5PC110 / S5PV210
19	
20	
21	S3C24XX Systems
22	---------------
23	
24	  There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
25	  deals with the architecture and drivers specific to these devices.
26	
27	  See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
28	  on the implementation details and specific support.
29	
30	
31	Configuration
32	-------------
33	
34	  A number of configurations are supplied, as there is no current way of
35	  unifying all the SoCs into one kernel.
36	
37	  s5p6440_defconfig - S5P6440 specific default configuration
38	  s5pc100_defconfig - S5PC100 specific default configuration
39	  s5pc110_defconfig - S5PC110 specific default configuration
40	  s5pv210_defconfig - S5PV210 specific default configuration
41	
42	
43	Layout
44	------
45	
46	  The directory layout is currently being restructured, and consists of
47	  several platform directories and then the machine specific directories
48	  of the CPUs being built for.
49	
50	  plat-samsung provides the base for all the implementations, and is the
51	  last in the line of include directories that are processed for the build
52	  specific information. It contains the base clock, GPIO and device definitions
53	  to get the system running.
54	
55	  plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
56	
57	  plat-s5p is for s5p specific builds, and contains common support for the
58	  S5P specific systems. Not all S5Ps use all the features in this directory
59	  due to differences in the hardware.
60	
61	
62	Layout changes
63	--------------
64	
65	  The old plat-s3c and plat-s5pc1xx directories have been removed, with
66	  support moved to either plat-samsung or plat-s5p as necessary. These moves
67	  where to simplify the include and dependency issues involved with having
68	  so many different platform directories.
69	
70	  It was decided to remove plat-s5pc1xx as some of the support was already
71	  in plat-s5p or plat-samsung, with the S5PC110 support added with S5PV210
72	  the only user was the S5PC100. The S5PC100 specific items where moved to
73	  arch/arm/mach-s5pc100.
