This provides a capable bootloader that may be run from OCRAM.
The OCRAM contains regions that are always zero, so the linker
file avoids those with best effort.
iMX9 infrastructure expects:
- 0x20480000 (Start of OCRAM, AHAB)
- 0x2049a000 (NuttX or SPL)
- 0x204e0000 (ARM Trustzone, not used)
When started from SD-card, the offsets are:
- 0x1f000 with AHAB
- 0xa000 without AHAB
