1 SPEAr ARM Linux Overview
2 ==========================
3
4Introduction
5------------
6
7 SPEAr (Structured Processor Enhanced Architecture).

9
10 The ST Microelectronics SPEAr range of ARM9/CortexA9 System-on-Chip CPUs are
11 supported by the 'spear' platform of ARM Linux. Currently SPEAr300,
12 SPEAr310, SPEAr320 and SPEAr600 SOCs are supported. Support for the SPEAr13XX
13 series is in progress.
14
15 Hierarchy in SPEAr is as follows:
16
17 SPEAr (Platform)
18 - SPEAr3XX (3XX SOC series, based on ARM9)
19 - SPEAr300 (SOC)
20 - SPEAr300_EVB (Evaluation Board)
21 - SPEAr310 (SOC)
22 - SPEAr310_EVB (Evaluation Board)
23 - SPEAr320 (SOC)
24 - SPEAr320_EVB (Evaluation Board)
25 - SPEAr6XX (6XX SOC series, based on ARM9)
26 - SPEAr600 (SOC)
27 - SPEAr600_EVB (Evaluation Board)
28 - SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
29 - SPEAr1300 (SOC)

31 Configuration
32 -------------
33
34 A generic configuration is provided for each machine, and can be used as the
35 default by
36 make spear600_defconfig
37 make spear300_defconfig
38 make spear310_defconfig
39 make spear320_defconfig
40
41 Layout
42 ------
43
44 The common files for multiple machine families (SPEAr3XX, SPEAr6XX and
45 SPEAr13XX) are located in the platform code contained in arch/arm/plat-spear
46 with headers in plat/.
47
48 Each machine series have a directory with name arch/arm/mach-spear followed by
49 series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx.
50
51 Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c and for
52 spear6xx is mach-spear6xx/spear6xx.c. mach-spear* also contain soc/machine
53 specific files, like spear300.c, spear310.c, spear320.c and spear600.c.
54 mach-spear* also contains board specific files for each machine type.
