Merge branch 'sti/soc' into next/late
From Srinivas Kandagatla <srinivas.kandagatla@st.com>: This patch-set adds basic support for STMicroelectronics STi series SOCs which includes STiH415 and STiH416 with B2000 and B2020 board support. STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in Set-top-boxes. The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support. The reason for adding two SOCs at this patch set is to show that no new C code is required for second SOC(STiH416) support. * sti/soc: ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support Signed-off-by: Olof Johansson <olof@lixom.net>

STi ARM Linux Overview
|
||||
==========================
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
The ST Microelectronics Multimedia and Application Processors range of
|
||||
CortexA9 System-on-Chip are supported by the 'STi' platform of
|
||||
ARM Linux. Currently STiH415, STiH416 SOCs are supported with both
|
||||
B2000 and B2020 Reference boards.
|
||||
|
||||
|
||||
configuration
|
||||
-------------
|
||||
|
||||
A generic configuration is provided for both STiH415/416, and can be used as the
|
||||
default by
|
||||
make stih41x_defconfig
|
||||
|
||||
Layout
|
||||
------
|
||||
All the files for multiple machine families (STiH415, STiH416, and STiG125)
|
||||
are located in the platform code contained in arch/arm/mach-sti
|
||||
|
||||
There is a generic board board-dt.c in the mach folder which support
|
||||
Flattened Device Tree, which means, It works with any compatible board with
|
||||
Device Trees.
