So blackfin, m68k, and mips seems to have it possible to enable,

Hint: CONFIG_EARLY_PRINTK covers far more than early_printk()
I know this.
Note also I didn't specify CONFIG_EARLY_PRINTK,
just early_printk.
Is early_printk really used by these architectures?
Should it be removed?
Sure, if you have a good reason to remove working functionality.
Unused.
Ideally, all direct early_printk() uses would go away.
This would just be a starting point to minimize code.
