For the e300 core, we can see the d-cache is locked as SRAM for the stack in
start.S file by calling the function lock_ram_in_cache:
---
arch/powerpc/cpu/mpc83xx/start.S
#ifdef CONFIG_SYS_INIT_RAM_LOCK
bl lock_ram_in_cache
sync
#endif
---
But we do not unlock the 4-KB d-cache which we locked in start.S for e300
---
arch/powerpc/lib/board.c
#if defined(CONFIG_SYS_INIT_RAM_LOCK) defined(CONFIG_E500)
unlock_ram_in_cache(); /* it's time to unlock D-cache in e500 */
#endif

The use of Microsoft crippleware systems is a sin that carries with
it its own punishment.
