I give another thought about it. We have to be sure that the flash
device will be online when it's really needed.
module_init initcall is quite far in the boot process. Is it what we want?

This is no problem, the flash driver is needed when the root file system
is mounted. The arch code reads the SoC configuration values in its own
code in arch/mips/bcm47xx/nvram.c without using the mtd subsystem. These
values are needed very early in the boot process.
