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.
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!
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.
NOTE: If Ben doesn't merge the setup files, may need to change this to
point to setup_32.c
I will describe later the boot process and various callbacks that
your platform should implement.

Currently, there are many devices on SOCs that do not have a standard

specifications, mainly because the boards that contain these SOCs are
