Have a look at http://git.pengutronix.de/?p=str/barebox.git;a=summary I "stole" your clk driver and added it to my patch stack :-) Current state for ZedBoard: - boot first stage from SD-Card - barebox.bin needs to be processed with ./scripts/zynq_checksum barebox.bin BOOT.bin to have the checksum in the BootROM header - clocksource is arm_smp_tmd at seems accurate - the BootROM needs about 4-5 seconds to copy barebox from SD to the OCM. I guess, I need to mess with the SD setup in the BootROM somehow - just enough clkdev to use the timer - all pinctrl, clk setup etc happens in the lowlevel init Regards, Steffen -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
