Commit7f107887d1("ARM: dts: imx: Remove skeleton.dtsi") causes boot issues when the bootloader does not create a 'chosen' node if such node is not present in the dtb. The reason for the boot failure is well explained by Javier Martinez Canillas: "the decompressor relies on a pre-existing chosen node to be available to insert the command line and merge other ATAGS info." , so pass an empty 'chosen' node to fix the boot problem. This issue has been seen in the kernelci reports with Barebox as bootloader. Also pass the 'memory' node in order to fix boot issues on the SolidRun iMX6 platforms.
