* Child driver for ChipCommon core.

* This is not MI code at the moment.
|
||||
* Two 16C550 compatible UARTs live here. On the WGT634U, uart1 is the
|
||||
* system console, and uart0 is not pinned out.
|
||||
* Because their presence is conditional, they should probably
|
||||
* be attached from here.
|
||||
* GPIO lives here.
|
||||
* The hardware watchdog lives here.
|
||||
* Clock control registers live here.
|
||||
* You don't need to read them to determine the clock speed on the 5365,
|
||||
* which is always 200MHz and thus may be hardcoded (for now).
|
||||
* Flash config registers live here. There may or may not be system flash.
|
||||
* The external interface bus lives here (conditionally).
|
||||
* There is a JTAG interface here which may be used to attach probes to
|
||||
* the SoC for debugging.
