- IMX6 OCRAM (IRAM) is from 0x00907000 to 0x0093FFFF
That's not true for all IMX6 SoCs. On i.MX6 Solo and DualLite it's 0x00907000 to 0x0091FFFF.
- we start at 0x00908000 so as to leave some room for IVT/DCD
- recommended stack (from IMX6DQRM Figure 8-3) is at 0x0093FFB8
- this leaves about 224K for SPL image and stack

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).
