From b1ab95c63622e9d9bd0ce685e149034d393afc2e Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 5 Nov 2018 14:54:27 -0800 Subject: arch: Make phys_initrd_start and phys_initrd_size global variables Make phys_initrd_start and phys_initrd_size global variables declared in init/do_mounts_initrd.c such that we can later have generic code in drivers/of/fdt.c populate those variables for us. This requires both the ARM and unicore32 implementations to be properly guarded against CONFIG_BLK_DEV_INITRD, and also initialize the variables to the expected default values (unicore32).
