microblaze: Add support for CCF
Add support for CCF for Microblaze.
Old binding:
system_timer: system-timer@41c00000 {
clock-frequency = <75000000>;
...
}
New binding:
system_timer: system-timer@41c00000 {
clocks = <&clk_bus>;
...
}
Both should be supported for a while
Microblaze clock binding:
clocks {
#address-cells = <1>;
#size-cells = <0>;
clk_bus: bus {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "bus";
compatible = "fixed-clock";
reg = <1>;
} ;
clk_cpu: cpu {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "cpu";
compatible = "fixed-clock";
reg = <0>;
} ;
} ;

with big endian conversion.

microblaze: Unprivileged stream instruction awareness
Add cpuinfo support for the new MicroBlaze option permitting userspace
(unprivileged) access to the streaming instructions (FSL / AXI-stream).
Emit a noisy warning at bootup if this is enabled, because bad user code
can potentially lockup the CPU.

microblaze: Support timer on AXI lite
New microblaze systems uses two buses. One for memories
and flashes and the second for low-speed peripherals
which can run on different CLK. This is the reason
why the kernel is trying to read clock-frequency
directly from node. If there is then the kernel will
work with it. If not then cpu CLK is used.

microblaze: Add support for little-endian Microblaze
Microblaze little-endian toolchain exports __MICROBLAZEEL__
which is used in the kernel to identify little/big endian.
The most of the changes are in loading values from DTB which
is always big endian.
Little endian platforms are based on new AXI bus which has
impact to early uartlite initialization.

There is missing checking agains PVR but this is not important
for now. There are some missing checking too.
