The way all of the memory init code here works is that we pass 0xDEADBEEF around for the initial value (as it's a well known 'poison' value and so easily recognized in debuggers, etc). The only point of this CONFIG symbol was to pass in a different value for that purpose. Drop this symbol and cleanup the code slightly. Signed-off-by: Tom Rini <trini@konsulko.com>
