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.
Signed-off-by: Simon Glass sjg@chromium.org --- Changes in v2: - Unify show_boot_progress() into this series
Changes in v3: - Update commit message to clarify the purpose of CONFIG_BOOTSTAGE_REPORT
