Looks like you don't use PLL2 as the UART clock anyomore. Please expland a bit further on the new UART clock sheme. > > Signed-off-by: Sebastian Reichel <sebastian.reic...@collabora.co.uk> > --- > arch/arm/mach-imx/mx5/lowlevel_init.S | 4 ++++ > 1 file changed, 4 insertions(+) > > diff --git a/arch/arm/mach-imx/mx5/lowlevel_init.S > b/arch/arm/mach-imx/mx5/lowlevel_init.S > index f5bc6728b7c2..ee4c3afd2fed 100644 > --- a/arch/arm/mach-imx/mx5/lowlevel_init.S > +++ b/arch/arm/mach-imx/mx5/lowlevel_init.S > @@ -319,11 +319,13 @@ setup_pll_func: > ldr r1, =0x00016154 > str r1, [r0, #CLKCTL_CBCMR] > > +#if !defined(CONFIG_TARGET_MX53PPD) It would be better if this option could be a generic one, something like CONFIG_MX53_SERIAL_HIGHBAUD, so that other boads could use it if needed. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
