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