a40979407f Tiva Timer: Revert the previous change. Thre is a better way to handler timerout interrupts. 
Removed setting of the initial timer interval load value (or, rather, it is always set to zero for a free-running timer).  Also, do not unconditional enable the timer out interrupt.  The timerout interrupt is not not enabled until tiva_timer32_setinterval() is called.

1842525cc2 MMCSD SDIO: Add support for a new SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop to pool the card R1 start to determine when the card was ready for the next transfer. That busy-wait can be quite long -- hundreds of milliseconds. And alternative is to look the the SD D0 pin which will change state when the card is no longer busy. 
This logic implements a change the avoids the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, then waiting for the card to becom ready without taking up CPU cycles.

This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE and is currenlty only implemented for the STM32 SDIO driver.

5e0571f5a8 stm32-rtc: Add support for the internal low speed clock (LSI) 
Some boards do not have the external 32khz oscillator installed, for those boards we must fallback to the crummy to the crummy internal RC clock.  Turn on by defining CONFIG_RTC_LSICLOCK.
