Isn't there auto training code for i.MX8 as it is for i.MX6Q?

For example: 
https://gitlab.denx.de/u-boot/u-boot/blob/master/arch/arm/mach-imx/mx6/ddr.c

Shouldn't those pins be configured via DTS/DM? As fair as I see this is
the imx8mn_evk.c file (which seems not to be the SPL).

This also seems like not DM/DTS code.

Shouldn't the number of mmc device be get via alias defined in DTS (or
assigned automatically)? 

What is the purpose of this function?

Is this correct that in the SPL you call probe on all UCLASS_CLK
devices registered for i.MX8?

You could also from the beginning enable CONFIG_WDT and CONFIG_SYSRESET
(as i.MX6 already uses it).

Please correct me if I'm wrong, but why do you use 'booti' (and
presumably boot Image?).

Please use fitImage (in think that it is mature enough to be used for
new ports - other imx SoCs use it already for some time); 

It can be called as: bootm ${loadaddr}#conf@${fdt_conf}

Has the i.MX8 the use case for IMX_BOOTAUX - if not please remove it.

Those #defines (I2C related) are already supported in Kconfig. Please
use them.


Please review above defines and move to Kconfig.
