This patch set brings automatic probing of DT clock providers to ARM barebox, similar to what we have in Linux kernel.
First, a new macro BAREBOX_CLK_TABLE for generic linker scripts is added, that will take all declared DT clock providers. That macro is then added to the ARM linker script. Then, barebox compatible versions of of_clk_init and CLK_OF_DECLARE are added, that allow to parse and probe declared clock providers. The of_clk_init call is then put right after of_platform_populate in of_probe. Finally, clk/fixed is declared as such a clock provider and can now be probed automatially for DT enabled ARM platforms.
