In case of booting from RAM (CONFIG_SYS_RAMBOOT), a TLB entry is created for IVPR + IVOR15 to map on valid OP code address. This TLB entry shall not be protected against invalidation, because a new TLB entry to access RAM in AS0 will be created by cpu_init_early_f. If this TLB entry is protected against invalidation, this will creates 2 TLB for the same address range (forbidden).
Instead we should explicitly remove the debug TLB when it is no longer needed.
