[U-Boot] [PATCH 06/21] sandbox: Zero the ram buffer on startup

[sjg at google.com]

At present the RAM buffer is not inited unless it is read from a file,
likely produced by an earlier phase of U-Boot. This causes valgrind
warnings whenever the RAM buffer is used. Correct this by initing it if
needed.
