+ 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.

-What: corgikbd, spitzkbd, tosakbd driver
-When: 2.6.35
-Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
-Why: We now have a generic GPIO based matrix keyboard driver that
- are fully capable of handling all the keys on these devices.
- The original drivers manipulate the GPIO registers directly
- and so are difficult to maintain.

-What: corgi_ssp and corgi_ts driver
-When: 2.6.35
-Files: arch/arm/mach-pxa/corgi_ssp.c, drivers/input/touchscreen/corgi_ts.c
-Why: The corgi touchscreen is now deprecated in favour of the generic
- ads7846.c driver. The noise reduction technique used in corgi_ts.c,
- that's to wait till vsync before ADC sampling, is also integrated into
- ads7846 driver now. Provided that the original driver is not generic
- and is difficult to maintain, it will be removed later.

+ * (3) the peripheral's bus & kernel clock at the PRCC level
+ *
+ * (1) and (2) are handled by defining clk structs (DEFINE_PRCMU_CLK) for each
+ * of the cluster and peripheral clocks, and hooking these as the parents of
+ * the individual peripheral clocks.
+ *
+ * (3) is handled by specifying the bits in the PRCC control registers required
+ * to enable these clocks and modifying them in the ->enable and
+ * ->disable callbacks of the peripheral clocks (DEFINE_PRCC_CLK).
+ *
+ * This structure describes both the PRCMU-level clocks and PRCC-level clocks.

+ Historically, the kernel has used strongly ordered mappings to

+
+ Multiple mappings with differing attributes is also unpredictable

+
+ However, drivers may be missing the necessary barriers for ARMv6,
