From 118f4d4559a4386fa87a1e2509e84a1986b24a34 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 5 Mar 2019 04:25:55 +0100 Subject: lib: fdt: Split fdtdec_setup_memory_banksize() Split fdtdec_setup_memory_banksize() into fdtdec_setup_memory_banksize_fdt(), which allows the caller to pass custom blob into the function and the original fdtdec_setup_memory_banksize(), which uses the gd->fdt_blob. This is useful when configuring the DRAM properties from a FDT blob fragment passed in by the firmware.
