Hi,
I am working on a board (AMOS820 from Via) based on the mx6qsabrelite.
The BSP provided by the manufacturer is quite old. I managed to port it from Freescale uboot-imx rel_imx_3.0.35_4.1.0 to u-boot mainline, and basically the latest issue I have is the cpu frequency.
The kernel I use is the rel_imx_3.0.35_4.1.0 as well (same tag name)
With the old u-boot, it runs at 1Ghz because the BSP explicitly has a call to
clk_config(CONFIG_REF_CLK_FREQ, 1000, CPU_CLK);
With the new u-boot, it runs at default freq which is 800Mhz (at least, what I guess from the Bogomips because no other log says it) I have attempted to pass "arm_freq=1000" to the boot args but that does not change anything.
My concern is that clk_config does not seem to be available anymore, there is get_mcu_main_clk but no set routine.
I wonder if it is intentional, I could write a set routine but I wonder if it could be accepted as a patch. What it your advice about it ?
Regards Thierry
