include	arch/arm/src/imxrt: Add framework for eDMA support. Initial port is a rip off from the SAMA5Dx and is little more than the framework for the DMA support.	2018-05-16 14:28:22 -06:00

Kconfig	Back out part of f4bcaa4fc2dc2f06d5632d3b74f43c25a6e7e845.If CONFIG_ARCH_IDLE_CUSTOM is defined, then it should not use the version of lc823450_idle.c in arch/arm/src/lc823450. That part was correct before the PR. If CONFIG_ARCH_IDLE_CUSTOM, then the build should use a custom IDLE loop in the board src/ directory.	2018-05-11 06:26:01 -06:00
