1 SPEAr ARM Linux Overview
2 ==========================
7 SPEAr (Structured Processor Enhanced Architecture).

10 The ST Microelectronics SPEAr range of ARM9/CortexA9 System-on-Chip CPUs are
11 supported by the 'spear' platform of ARM Linux. Currently SPEAr1310,
12 SPEAr1340, SPEAr300, SPEAr310, SPEAr320 and SPEAr600 SOCs are supported.
14 Hierarchy in SPEAr is as follows:
17 - SPEAr3XX (3XX SOC series, based on ARM9)
19 - SPEAr300 Evaluation Board
21 - SPEAr310 Evaluation Board
23 - SPEAr320 Evaluation Board
24 - SPEAr6XX (6XX SOC series, based on ARM9)
26 - SPEAr600 Evaluation Board
27 - SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
29 - SPEAr1310 Evaluation Board
31 - SPEAr1340 Evaluation Board
36 A generic configuration is provided for each machine, and can be used as the
38 make spear13xx_defconfig
39 make spear3xx_defconfig
40 make spear6xx_defconfig
45 The common files for multiple machine families (SPEAr3xx, SPEAr6xx and
46 SPEAr13xx) are located in the platform code contained in arch/arm/plat-spear
47 with headers in plat/.
49 Each machine series have a directory with name arch/arm/mach-spear followed by
50 series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx.
52 Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c, for
53 spear6xx is mach-spear6xx/spear6xx.c and for spear13xx family is
54 mach-spear13xx/spear13xx.c. mach-spear* also contain soc/machine specific
55 files, like spear1310.c, spear1340.c spear300.c, spear310.c, spear320.c and
56 spear600.c. mach-spear* doesn't contains board specific files as they fully
57 support Flattened Device Tree.
