The SDHI IP came from the SH7269 (SH-2A device).

For the VERSION register, the low byte is the version of the IP, but the upper byte is a number that the design group that made the part gives it any time they make a change. So, since this IP was from a SH2A team, the numbering might look different than what the SH4A or R-Car teams have used in the past.

0xE804E0E4 = 0x0001

So...something is there!
