microblaze: Remove early printk setup

2020-02-25T11:33:19+00:00

Early printk has been removed already that's why this setting doesn't make
any sense. Also change printk level from pr_info to pr_err.

microblaze: Add support for CCF

2014-01-27T10:24:55+00:00

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>;
	} ;
} ;

microblaze: Unprivileged stream instruction awareness

2011-07-25T07:13:42+00:00

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.

We used cache_line as cache_line_lenght. For this reason
we did cache flushing 4 times longer than was necessary.
