Applied to u-boot-imx, master, thanks !

I was hoping to finish this this afternoon, but a family emergency
came up. I'm going to try to finish it later tonight or tomorrow.
It's taking a bit longer because there are some boards with DDR4,
LPDDR4 and DDR3. I don't have most of them, but I plan to at least
generate a flash.bin file before posting it.

This is a temporary fix until I generate the common imx8mn-u-boot.dtsi
which will include this.

Are you going to include it in imx8mn-u-boot.dtsi or do we need to
patch every single board?

[PATCH] arm: dts: imx8mn-beacon-kit-u-boot: Fix broken booting
When the imx8mm.dtsi file was pulled in from Linux, the UARTs
were moved into an spba sub-node which wasn't being included
in the SPL device tree. This meant the references to the UART
weren't being handled properly and when booting the system would
constantly reboot. Fix this by adding the spba node to the spl
device tree to restore normal booting.
Fixes: 4e5114daf9eb ("imx8mn: synchronise device tree with linux")
