That's not true for all IMX6 SoCs. On i.MX6 Solo and DualLite it's
0x00907000 to 0x0091FFFF.

This should be a smaller value if we want this config to apply for
i.MX6 Solo and DualLite, which have a 68KB OCRAM free area.

For i.MX6 Solo and DualLite this address should be lower (recommended
address is 0x0091FFB8).
