From b188067f39627d977bb1db67c8456e9aaab90743 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 8 Jan 2015 18:18:25 +0100 Subject: [PATCH] arm: vf610: fix boot from SD-card Boot from SD-card (and probably also from NAND) was broken since commit d6d07a9bec ("arm: vf610: add NAND support for vf610twr"). It looks like the increased size of U-Boot lead to a situation where the boot ROM overwrote its own stack/heap while loading U-Boot from the SD-card to the SRAM. However, U-Boot worked fine when loaded through USB serial loader directly into SRAM. It looks like loading from SD-card uses other stack/heap location then the serial loader (or maybe no stack or heap at all). This fix moves U-Boot to gfxRAM, which is 512kB in size and is not used by the boot ROM nor the SD-card loader of it.
