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 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. |
