Now the system uses 2.14.0 version. Add only necessary drivers: - pit - pmu - rtwdog - snvs_hp - snvs_lp - src - trng - wdog - gpio - gpt - lpi2c - lpuart - lpuart_edma - common - common_arm - dmamux - edma - flexram - flexram_allocate - clock - cache - CMSIS - dcp - iomuxc Changed speed of the USDHC clock from ~109MHz to ~81MHz. Also changed bus timing from kMMC_HighSpeedTiming to kMMC_HighSpeed200Timing for better efficiency.
