This approach can be used on normal boards as well as sandbox.
+When debugging with gdb, it's better to disable Link Timer Optimizations
+(CONFIG_LTO = n).
CC_OPTIMIZE_FOR_DEBUG should be mentioned here too.
I will add this when merging.
Should CC_OPTIMIZE_FOR_DEBUG disable LTO?
The usefulness of LTO=n, CC_OPTIMIZE_FOR_DEBUG=y for debugging is not
sandbox specific but applies to QEMU and JTAG debugging too.
I think the section "Debugging the init sequence" should not live on a
page that is sandbox specific. Instead we should add a new page on
debugging U-Boot.
