/*
|

|
|
* We use absolute address not PC relative address to jump.
|
||
|
|
* When running SPL on iMX8, the A core starts at address 0, a alias to OCRAM 0x100000,
|
||
|
|
* our linker address for SPL is from 0x100000. So using absolute address can jump to
|
||
|
|
* the OCRAM address from the alias.
|
||
|
|
* The alias only map first 96KB of OCRAM, so this require the SPL size can't beyond 96KB.
|
||
|
|
* But when using SPL DM, the size increase significantly and may exceed 96KB.
|
||
|
|
* That's why we have to jump to OCRAM.
