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). --- Changes form v1 - Added CONFIG guards - Clarified documentation --- Svyatoslav Ryhel (1): boot: pxe_utils: skip fdt setup in case legacy kernel is booted boot/pxe_utils.c | 27 ++++++++++++++++++++++----- doc/develop/distro.rst | 6 ++++++ 2 files changed, 28 insertions(+), 5 deletions(-) -- 2.40.1
