      8  SPEAr (Structured Processor Enhanced Architecture).

     10
     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.
     14
     15  Hierarchy in SPEAr is as follows:
     16
     17  SPEAr (Platform)
     18
     19	- SPEAr3XX (3XX SOC series, based on ARM9)
     20		- SPEAr300 (SOC)
     21			- SPEAr300 Evaluation Board
     22		- SPEAr310 (SOC)
     23			- SPEAr310 Evaluation Board
     24		- SPEAr320 (SOC)
     25			- SPEAr320 Evaluation Board
     26	- SPEAr6XX (6XX SOC series, based on ARM9)
     27		- SPEAr600 (SOC)
     28			- SPEAr600 Evaluation Board
     29	- SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
     30		- SPEAr1310 (SOC)
     31			- SPEAr1310 Evaluation Board
     32		- SPEAr1340 (SOC)
     33			- SPEAr1340 Evaluation Board

     35Configuration
     36-------------
     37
     38  A generic configuration is provided for each machine, and can be used as the
     39  default by::
     40
     41	make spear13xx_defconfig
     42	make spear3xx_defconfig
     43	make spear6xx_defconfig
     44
     45Layout
     46------
     47
     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/.
     51
     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.
     54
     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.
