[PATCH 0/3] of/fdt: Rework early FDT scanning functions

From: Rob Herring
Date: Thu Nov 18 2021 - 13:12:17 EST


The early FDT scanning functions use of_scan_flat_dt() which implements
its own node walking method. This function predates libfdt and is an
unnecessary indirection. This series reworks
early_init_dt_scan_chosen(), early_init_dt_scan_root(), and
early_init_dt_scan_memory() to be called directly and use libfdt calls.

Ultimately, I want to remove of_scan_flat_dt(). Most of the remaining
of_scan_flat_dt() users are in powerpc.
