Kinetis variant upgrade
This upgrade of Kinetis port brings support for K70 family as well as variant
upgrades.
New features:
- Clocking: driver supports second PLL1 oscillator;
- eDMA now supports 32 channel controllers such as one found on K70;
- DDRAM support;
- Cache is supported (present on 120 and 150 MHz devices) (gives tremendous
boost to processing of code and data residing in DDRAM or Flash)
- SPI driver has been upgraded to cope with cached memory;
- Ethernet driver has been upgraded to use non-cached memory regions for
TCDs and buffers.
