f1c79423e1 The STM32F4Discovery board doesn't come with a Low speed external oscillator so the default LSE source for the RTC doesn't work. 
In stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call that rightfully enables the lsi clock; but the next times, when the rtc is already setup, the rtc_resume() call does NOT start the lsi clock!

The right place to put LSE/LSI initialisation is inside stm32_stdclockconfig() in stm32fxxxxx_rcc.c.  Doing this I checked the possible uses of the LSI and the LSE sources: the LSI can be used for RTC and/or the IWDG, while the LSE only for the RTC (and to output the MCO1 pin)..

This change is not verifed for any other platforms.

dab3dbc75b Cortex-M7: Add support for enabled the D-Cache in write only mode. 
SAMV7 Ethernet:  I- and D-Cache are now enabled in the netnsh/ configuration.  D-Cache is enabled in write-though mode.  This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.

a60fa12e86 Clean up pointer handling to make code more readability. This re-introduces the compiler optimization problem but this is the correct thing to do. I will have to drop back from -Os to -O2. 2015-03-28 14:46:35 -06:00

d7dbdfef58 SAMV7 EMAC: Sometimes TX is not started when TSTART is set??? Workaround seems to be to set it twice. Restored full optimization. Also CONFIG_NET_NOINTS is set so that interrupt level provessing is avoided 2015-03-28 09:42:45 -06:00

f3ad3efcb4 - ADC driver has been re-organized; configuration is now handled in code 
instead of Kconfig to help reduce bloat and confusion.
- Timer changed to remove ADC coupling in Kconfig to code and moved
configuration up from arch/arm/src/tiva to configs/tm4c123g-launchpad/src.
- GPIO driver needed small fixes in the configuration routines and
discovered false-positive bugs in interrupt testing: interrupts are now
verified to actually be working reliably.
- Attempt to apply some consistency in the tiva arch/ level's interface
to the config/board/ level driver configuration.
