Re: Clocks on Barebox

[andreas.willig@rafi.de]

Hi Sascha,

here my oftables section from barebox.map:

.oftables       0x278f7bc0       0x18
                0x278f7bc0                . = ALIGN (0x8)
                0x278f7bc0                __clk_of_table_start = .
 *(.__clk_of_table_*)
 .__clk_of_table_end
                0x278f7bc0        0x8 drivers/built-in.o
                0x278f7bc0                __clk_of_table_sentinel
 .__clk_of_table_fixed_clk
                0x278f7bc8        0x8 drivers/built-in.o
                0x278f7bc8                __clk_of_table_fixed_clk
 .__clk_of_table_fixed_factor_clk
                0x278f7bd0        0x8 drivers/built-in.o
                0x278f7bd0                __clk_of_table_fixed_factor_clk
                0x278f7bd8                __clk_of_table_end = .

from imx6qdl.dtsi:
...
    clocks {
        #address-cells = <1>;
        #size-cells = <0>;
        ckil {
            compatible = "fsl,imx-ckil", "fixed-clock";
            #clock-cells = <0>;
            clock-frequency = <32768>;
        };
        ckih1 {
            compatible = "fsl,imx-ckih1", "fixed-clock";
            #clock-cells = <0>;
            clock-frequency = <0>;
        };
        osc {
            compatible = "fsl,imx-osc", "fixed-clock";
            #clock-cells = <0>;
            clock-frequency = <24000000>;
        };
    };
...

I' m not quite sure how to read the barebox.map at this Point. Do I have clocks in Image or not? The parsercode just breaks out without finding any enumerated items....

Do you mean the clk_of_table is empty? Could you post an excerpt from
you barebox.map file containing the __clk_of_table? Here it looks like:

                0x0000000000092178                __clk_of_table_start =
.
 *(.__clk_of_table_*)
 .__clk_of_table_fixed_clk
                0x0000000000092178        0x8 drivers/built-in.o
                0x0000000000092178
__clk_of_table_fixed_clk
 .__clk_of_table_fixed_factor_clk
                0x0000000000092180        0x8 drivers/built-in.o
                0x0000000000092180
__clk_of_table_fixed_factor_clk
 .__clk_of_table_end
                0x0000000000092188        0x8 drivers/built-in.o
                0x0000000000092188
__clk_of_table_sentinel
                0x0000000000092190                __clk_of_table_end = .
