Currently SPEAr1310, SPEAr1340, SPEAr300, SPEAr310, SPEAr320 and SPEAr600 SOCs are supported. Hierarchy in SPEAr is as follows: SPEAr (Platform) - SPEAr3XX (3XX SOC series, based on ARM9) - SPEAr300 (SOC) - SPEAr300 Evaluation Board - SPEAr310 (SOC) - SPEAr310 Evaluation Board - SPEAr320 (SOC) - SPEAr320 Evaluation Board - SPEAr6XX (6XX SOC series, based on ARM9) - SPEAr600 (SOC) - SPEAr600 Evaluation Board - SPEAr13XX (13XX SOC series, based on ARM CORTEXA9) - SPEAr1310 (SOC) - SPEAr1310 Evaluation Board - SPEAr1340 (SOC) - SPEAr1340 Evaluation Board Configuration ------------- A generic configuration is provided for each machine, and can be used as the default by:: make spear13xx_defconfig make spear3xx_defconfig make spear6xx_defconfig Layout ------ The common files for multiple machine families (SPEAr3xx, SPEAr6xx and SPEAr13xx) are located in the platform code contained in arch/arm/plat-spear with headers in plat/. Each machine series have a directory with name arch/arm/mach-spear followed by series name. Like mach-spear3xx, mach-spear6xx and mach-spear13xx. Common file for machines of spear3xx family is mach-spear3xx/spear3xx.c, for spear6xx is mach-spear6xx/spear6xx.c and for spear13xx family is mach-spear13xx/spear13xx.c. mach-spear* also contain soc/machine specific files, like spear1310.c, spear1340.c spear300.c, spear310.c, spear320.c and spear600.c. mach-spear* doesn't contains board specific files as they fully support Flattened Device Tree.
