+ SPEAr ARM Linux Overview
+ ==========================
+
+Introduction
+------------
+
+ SPEAr (Structured Processor Enhanced Architecture).
+ weblink : http://www.st.com/spear
+
+ The ST Microelectronics SPEAr range of ARM9/CortexA9 System-on-Chip CPUs are
+ supported by the 'spear' platform of ARM Linux. Currently SPEAr300,
+ SPEAr310, SPEAr320 and SPEAr600 SOCs are supported. Support for the SPEAr13XX
+ series is in progress.
+
+ Hierarchy in SPEAr is as follows:
+
+ SPEAr (Platform)
+ - SPEAr3XX (3XX SOC series, based on ARM9)
+ - SPEAr300 (SOC)
+ - SPEAr300_EVB (Evaluation Board)
+ - SPEAr310 (SOC)
+ - SPEAr310_EVB (Evaluation Board)
+ - SPEAr320 (SOC)
+ - SPEAr320_EVB (Evaluation Board)
+ - SPEAr6XX (6XX SOC series, based on ARM9)
+ - SPEAr600 (SOC)
+ - SPEAr600_EVB (Evaluation Board)
+ - SPEAr13XX (13XX SOC series, based on ARM CORTEXA9)
+ - SPEAr1300 (SOC)
+
+ Configuration
+ -------------
+
+ A generic configuration is provided for each machine, and can be used as the
+ default by
+ make spear600_defconfig
+ make spear300_defconfig
+ make spear310_defconfig
+ make spear320_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 and for
+ spear6xx is mach-spear6xx/spear6xx.c. mach-spear* also contain soc/machine
+ specific files, like spear300.c, spear310.c, spear320.c and spear600.c.
+ mach-spear* also contains board specific files for each machine type.
