Apparently its quite common NOT to check malloc()'s possible
NULL return value... At least most NET drivers don't seem to...

Maybe another RFC to avoid duplicating code:

malloc_cleared_panic() to allocate and clear memory for a
really required structure and put a proper panic message if that
fails. Assuming that continuing u-boot once a driver cannot even
be initialized is futile, that would save even more code in each
driver.
