[PATCH v2 0/1] Fix booting kernels with ATAGS and extlinux

[Svyatoslav Ryhel]

Currently, if boot with extlinux.conf and do not set the fdt
U-Boot will provide its own device tree. This behavior is
beneficial if the U-Boot device tree is in sync with Linux,
but it totally halts the booting of pre-dtb kernels (3.4 for
example) since it uses ATAGs. To fix this, pass `-` in the
fdt extlinux field as a signal that no tree should be used.

Tested with 3.4 legacy kernel and mainline 6.7 kernel on
P895 (lg_x3 board).
