From f933e84e3497bddf29b8183ca6ee37a7a12e9ac3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 13 Feb 2012 13:51:21 +0000 Subject: bootstage: arm: Add bootstage calls in board and bootm Add calls to bootstage before and after relocation, and just before jumping to the OS. The idea here is you can call bootstage_report() to get a report. Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is printed automatically by U-Boot just before jumping to the kernel.
