Using 50 MiB malloc pool in SPL is nonsense. Since the caches are not
enabled in SPL, it takes 2 seconds to init the pool and has no obvious
benefit. Reduce the size to 1 MiB.

thanks for dropping 2 secs off our time to boot!
Tim
The boot time for SPL and U-Boot can be reduced more if
CONFIG_SYS_MALLOC_CLEAR_ON_INIT is unset (default is set).
Then it doesn't matter what is the size of malloc pool but it's not
cleared - so needs check if malloc() calls should be changed to calloc().
Best regards,
