[U-Boot] raspberrypi0w issue when change cmdline.txt -> FDT_ERR_BADMAGIC

[Belisko Marek]

Hi,

I'm having strange issue that when update cmdline.txt in boot partition
(basically after first boot there is resize of data partition) then I get
this:
U-Boot 2018.07-g981cc831e3 (Mar 26 2019 - 11:14:55 +0100)

when checking fdt_addr there was no dtb loaded at all (juts 0xaa on that
address). When remove resize from cmdline.txt before booting then board
boots fine. Any ideas if broadcom FW can change something in that regard
and break things? Thanks for any pointers.

BR,
