Starting with v3.19, you should be able to use the earlycon framework on
arm32, so it would be better to replace earlyprintk with earlycon here
and add a stdout-path property in chosen that points to the console
uart.
64 hash table entries sounds extremely small, doesn't that impact
performance? If you have 50MB of actual RAM available, I don't think
you need that.
