This patch adds basic support for the Migo-R board. Only simple stuff provided by the cpu specific sh7722 code is in place now, like serial console port, timers and usb gadget. There is also partial support for the smc91c111 ethernet controller - unfortunately some driver header file also needs patching (not included here) to make the driver get IRQ sense information from the platform data.

|

kexec is a system call that implements the ability to shutdown your
|
|
current kernel, and to start another kernel. It is like a reboot
|
|
but it is independent of the system firmware. And like a reboot
|
|
you can start any kernel with it, not just Linux.
|
|
|
|
The name comes from the similarity to the exec system call.
|
|
|
|
It is an ongoing process to be certain the hardware in a machine
|
|
is properly shutdown, so do not be surprised if this code does not
|
|
initially work for you. It may help to enable device hotplugging
|
|
support. As of this writing the exact hardware interface is
|
|
strongly in flux, so no good recommendation can be made.
