i.MX25 SOC has a different CCM device than i.MX31. Qemu i.MX25 emulation was built with i.MX31 CCM driver. This allows Linux to work on top of the i.MX25 emultion but this is not correct.
Furthermore, other SOC we could emulate like i.MX6 have yet a different implementation of the CCM device. We then add an i.MX25 specific CCM Device and have the i.MX25 SOC use it.
