From cefd764222ee0d030b90e594f84eddeac7b9b423 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 24 Aug 2015 11:03:50 +0200 Subject: arm: mvebu: Fix internal register config on A38x Currently booting on A38x is broken. As the current code tries to detect the SoC family to disable the MMU for the A38x at runtime. But before the internal registers are switched to the new location (0xf100.0000), this runtime detection does not work. As all macros / defines are already assigned to the new location at 0xf100.0000. But the registers are sill mapped to the default location at 0xd000.0000. This patch now makes sure, no such runtime detection is used before the internal registers are configured to the new location. After this, the remaining cache cleanup is executed.

As the static variable "init_done" is not available at that early boot time. This patch moves it to explicitly to the data section, making it available at that time.

This patch now enables this "-p" feature also for SoCs with header version 1 (Armada XP / 38x etc). With this its possible now to use the UART boot mode without on images that are generated for other boot devices, like SPI. So no need to change BOOT_FROM to "uart" for UART xmodem booting any more.
