This series adds support for running valgrind against U-Boot's internal malloc. This allows for much more useful reports to be generated.
Some example output of valgrind run against u-boot/master with this branch applied may be found at [1]. Note that valgrind gives up around acpi. This feature still needs a lot of work on suppressions/hints to filter out the noise properly.
