Add a basic CPU driver that retrieves information about the microblaze CPU
core. cpu_ops handlers are implemented so that the "cpu" command can work
properly:
U-Boot-mONStR> cpu list
0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
U-Boot-mONStR> cpu detail
0: cpu@0 MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
ID = 0, freq = 50 MHz: L1 cache, MMU
Note: cpu_ver_lookup[] and family_string_lookup[] arrays were imported from
linux.

This allows drivers to be provided for CPUs and their type to be
|
|
specified in the board's device tree. For boards which support
|
|
multiple CPUs, then normally have to be set up in U-Boot so that
|
|
they can work correctly in the OS. This provides a framework for
|
|
finding out information about available CPUs and making changes.
