From 6943cc9732202b9c65990cff9f74cea6b8173e09 Mon Sep 17 00:00:00 2001 From: Horatiu Vultur Date: Wed, 24 Apr 2019 17:21:29 +0200 Subject: [PATCH] arch: mips: Update initrd_start and initrd_end Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which represents the start of kseg0 and represents a virtual address. Meaning that the initrd_start and initrd_end point somewhere kseg0. When these parameters are passed to linux kernel through DT they are pointing somewhere in kseg0 which is a virtual address but linux kernel expects the addresses to be physical addresses(in kuseg) because it is converting the physical address to a virtual one. Therefore update the uboot to pass the physical address of initrd_start and initrd_end by converting them using the function virt_to_phys before setting up the DT.
