From 755c7d9a6179ffb15829da34cbc818d7fb4de558 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 2 Feb 2016 21:11:28 +0900 Subject: [PATCH] ARM: uniphier: change stack pointer address for SPL No special reason for the current stack address 0x0ff08000. Change it to 0x00100000 to simplify the init_page_table. There are two types of SoCs in terms of the load address of SPL. [1] PH1-sLD3, PH1-LD4, PH1-sLD8 SPL is loaded at 0x00040000-0x0004ffff [2] PH1-Pro4, PH1-Pro5, ProXstream2, PH1-LD6b SPL is loaded at 0x00100000-0x0010ffff The new stack area (0x000f8000-0x00100000) should be safe for all the cases.
