Why do they need to be at the end? Also, at the end of what do they need to be?
At the end of omap34xx_cpu_suspend. As we don't know where in SRAM the
counters will be, the code accessing those counters addresses them
relative from (_omap_sram_idle + omap34xx_cpu_suspend_sz). Not sure if
this part of the code made it to linux-omap though.
I have not posted the change needed to expose these counters to
userspace waiting for the churn in sleep34xx.S to settle down.
