environment variable to the correct pathname before building U-Boot.
Using valgrind / memcheck
-------------------------
It is possible to run U-Boot under valgrind to check memory allocations:
valgrind u-boot
If you are running sandbox SPL or TPL, then valgrind will not by default
notice when U-Boot jumps from TPL to SPL, or from SPL to U-Boot proper. To
fix this, use:
valgrind --trace-children=yes u-boot
