As Nicolas was the one who originally wrote that code, while he was
working for Montavista and interacting with Intel, I'd be surprised
if he didn't try finding out what the right answer is to that fixme.
I suspect as the fixme remained that there was no clear answer.
Nicolas, can you shed any light on this:
static int
pxa2xx_pcmcia_frequency_change(struct soc_pcmcia_socket *skt,
unsigned long val,
struct cpufreq_freqs *freqs)
{
#warning "it's not clear if this is right since the core CPU (N) clock has no
effect on the memory (L) clock"
