The boot loader must load a device tree image (dtb) into system ram

32-bit embedded kernels:

|
||||
Currently, board support is essentially an exclusive config option.
|
||||
The kernel is configured for a single platform. Part of the reason
|
||||
for this is to keep kernels on embedded systems small and efficient;
|
||||
part of this is due to the fact the code is already that way. In the
|

future, a kernel may support multiple platforms, but only if the

A kernel image may support multiple platforms, but only if the
|

platforms feature the same core architecture. A single kernel build
|

cannot support both configurations with Book E and configurations

with classic Powerpc architectures.
|
||||
|
||||
32-bit embedded platforms that are moved into arch/powerpc using a
|
||||
flattened device tree should adopt the merged tree practice of
|
||||
setting ppc_md up dynamically, even though the kernel is currently
|
||||
built with support for only a single platform at a time. This allows
|
||||
unification of the setup code, and will make it easier to go to a
|
||||
multiple-platform-support model in the future.
|

2) Entry point for arch/arm

||||
|

NOTE: I believe the above will be true once Ben's done with the merge
|
||||
of the boot sequences.... someone speak up if this is wrong!
|

There is one single entry point to the kernel, at the start
|

of the kernel image. That entry point supports two calling

||||
conventions. A summary of the interface is described here. A full
|
||||
description of the boot requirements is documented in
|
||||
Documentation/arm/Booting
|
||||
|
||||
To add a 32-bit embedded platform support, follow the instructions
|
||||
for 64-bit platforms above, with the exception that the Kconfig
|
||||
option should be set up such that the kernel builds exclusively for
|
||||
the platform selected. The processor type for the platform should
|
||||
enable another config option to select the specific board
|
||||
supported.

||||
a) ATAGS interface. Minimal information is passed from firmware

2) Representing devices without a current OF specification
|
||||
----------------------------------------------------------
|
||||
|
||||
Currently, there are many devices on SOCs that do not have a standard
|
||||
representation pre-defined as part of the open firmware
|
||||
specifications, mainly because the boards that contain these SOCs are
|
||||
not currently booted using open firmware. This section contains
|
||||
descriptions for the SOC devices for which new nodes have been
|
||||
defined; this list will expand as more and more SOC-containing
|
||||
platforms are moved over to use the flattened-device-tree model.

|

|

should be added to the Documentation/devicetree/bindings directory.

Why: The original implementation of memsw feature enabled by

CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
|

kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
|

turned out to be not ideal because we cannot have the feature compiled
|

in and disabled by default and let only interested to enable it
|
||||
(e.g. general distribution kernels might need it). Therefore we have
|
||||
added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
|
||||
the both possibilities. If we remove noswapaccount we will have
|

less command line parameters with the same functionality and we

can also cleanup the parameter handling a bit ().
