Hi Miquel,
There is an ID collision with the chip of same density from the JV
family. Both chips are very similar in practice, it is mostly a matter
of electrical differences (mostly power consumption being lower).

As a significant difference, RV chips identify themselves as supporting
the new SFDP (rev F) field which forces an alternate write SR2
opcode (0x31).

This density wronly advertizes its size and requires a fixup for
Typo? 'wrongly'
Same in patch #20.

+ mtd_debug info /dev/mtd0
mtd.type = MTD_NORFLASH
mtd.flags = MTD_CAP_NORFLASH
mtd.size = 8388608 (8M)
Is mtd0 a 8MB partition?

Thanks,
Takahiro
