Thank to your last email, I finally managed to boot in secure mode with
(what I consider as) minimal changes:
- kernel_old=1
- CONFIG_SYS_TEXT_BASE=0
- halting other cores in start.S:reset
- commenting away line 113 in arch/arm/cpu/armv7/virt-v7.c:

Oh and I don't think there is a TZ Address space controller on the
raspberry, or at least I am not aware of any.

I tried what Stephen suggested, and just changing CONFIG_SYS_TEXT_BASE to
0x0 (with kernel_old=1) does not work: the board display some garbage on
the uart then hangs. The content of the garbage makes me thinks that
nothing is done to handle the four cores in this setting which ends up
badly. I exp

Hi,
I finally hacked my way through U-boot and I managed to add raspberry's
boot code inside U-boot so that it can start as usual when using kernel_old
= 1. I don't think
we want this as a final solution but it made me understand a few things
about U-boot architecture (in short: I added a new secti
