Dear José Miguel Gonçalves,
Jumping to board_init_r is not performed due to a bug on address
computation.
Is your CONFIG_SYS_TEXT_BASE configured correctly? I don't detect any
misbehavior on my arm926 boards.
Maybe because you are not using it to build an SPL?
I do ... and I use CONFIG_SPL_TEXT_BASE properly .
Please check the same chunk of code in other start.S for arm1176 and
armv7. They have the same code that I put for arm926ejs.
Please wait and please first explain what is the issue.
The issue is what I've explained in the patch comments. Without this
change the code never reaches board_init_r in the SPL and I think I have
all the configurations correctly set. If the bug is not from here please
suggest me what I need to change in the configuration in order to
correctly boot my board.
Relocation offsets are not needed when building SPL.
Do they cause any trouble?
No! Just not needed.
