> Currently the omapl138_lcdk has SKIP_LOWLEVEL_INIT set.
> The README states there is a variation of this for the ARM926EJ-S
> which allows the board to just skip the call to lowlevel_init()
> and do the normal CP15 init which enables the instruction cache.
>
> On the da850evm, this was shown to improve startup time.
>
> This patch switches SKIP_LOWLEVEL_INIT to SKIP_LOWLEVEL_INIT_ONLY
> thus, enabling the cache.
