arch/arm/src/imxrt: Add cache operations to permit the Ethernet driver to work with the D-Cache enabled, at least in write-through mode.
Author: Jake Choy <jakearcx@gmail.com>
arch/arm/src/imxrt: The Ethernet driver is now functional, at least with the D-Cache off. The final fix was for the reference clock that needs to be forced to provide and input (SION).
Author: Gregory Nutt <gnutt@nuttx.org>
Fix trivial coding standard issue.
configs/imxrt1050-evk: Correct CONFIG_RAM_SIZE in all configurations (5Kb not 5Mb). I don't believe that CONFIG_RAM_SIZE is used at all in the i.MX RT so this is as grievous an error as it seems. Also enabled built-in applications in all NSH configurations.
arch/arm/src/imxrt/imxrt_enet.c: Trivial and cosmetic.
Cosmetic update to comments.
arch/arm/src/imxrt/imxrt_enet.c: Oops.. put the PHY interrupt init hooks in the wrong place. That is a one-time initialization but imxrt_initphy() is called on each ifup.
arch/arm/src/imxrt/imxrt_enet.c: Add hooks for board-specific PHY initialization (not yet needed, but there when needed).
Remove dangling white space at the end of lines
arch/arm/src/imxrt/Kconfig: Add option for board-specific PHY initialization.
configs/imxrt1050-evk/src: Add basic logic to support PHY interrupts. Incomplete.. needs additional support in imxrt_enet.c to 1. call to initialize PHY interrupt features, and 2. IOCTL commands to access PHY registers.
configs/imxrt1050-evk/README.txt: Trivial update.
configs/imxrt1050-evk/netnsh/defconfig: Disable LED support because pins conflict with PHY. Enable device statists. Enable NSH ifup and ifdown commmands
arch/arm/src/imxrt: Use macros in imxrt_periphclks.h vs. direct CCM CCGR accesses in Ethernet driver.
arch/arm/src/imxrt: Misc changes for a clean compilation of Ethernet deriver. configs/imxrt1050-evk/netnsh: Add an NSH configuration for testing Ethernet.

arch/arm/src/imxrt: Initial WIP Ethernet driver.
arch/arm/src/imxrt: May eDMA channel linking a configuration option. Add support to select the DMA channel priority and pre-emption controls.
arch/arm/src/imxrt: Update some HowTo comments in the eDMA header file.
arch/arm/src/imxrt: Fix a logic error in parmater passing. Caller does not know actual channel number when setting up linked channel, only the channel handler.
arch/arm/src/imxrt: Fixes for clean eDMA driver build with Scatter/Gather enabled.
arch/arm/src/imxrt: Fixes for clean eDMA driver build with Scatter/Gather disabled.
arch/arm/src/imxrt: Add flags to DMA configuration to control transfer setup. Remove some user interfaces that are inconsistent with modular design.
arch/arm/src/imxrt: Update DMA channel interrupt handler.
arch/arm/src/imxrt: Add implementation of eDMA imxrt_dmach_start().
arch/arm/src/imxrt: Add implementation of eDMA imxrt_dmach_setup().
arch/arm/src/imxrt: Add eDMA imxrt_tcd_chanlink().
arch/arm/src/imxrt: Add eDMA imxrt_dmach_getcount; free allocated TCDs automatically when the DMA completes or is aborted.
arch/arm/src/imxrt: Add structures to support list of TCDs for Scatter/Gather DMA.
arch/arm/src/imxrt: Add eDMA imxrt_dmach_initconfig().
arch/arm/src/imxrt: Add eDMA imxrt_tcd_instantiate().
arch/arm/src/imxrt: Replacing some of the logic cloned from SAMv7 XDMAC with eDMA logic from NXP sample code. I am thinking that the eDMA is too complex to force into the same pattern as for other MCUs.
arch/arms/src/imxrt/imxrt_edma.c: Add support for in-memory TCDs.
arch/arm/src/imxrt/chip: Add an in-memory representation of the TCD in imxrt_edma.h
configs/stm32f4discovery/include/board.h: Add SPI DMA pins definitions to get CS43L22 audio DAC working
configs/stm32f4discovery/audio: Add board configuration for CS43L22 audio example
configs/stm32f4discovery: Update README
As with the MCU temperature and VREFINT measurement, this patch requires user to enable the corresponding channel first. For Vbat channel the ioctl cmd is IO_ENABLE_DISABLE_VBAT_CH, and its arg should be a pointer to bool which must be true to enable and false to disable the Vbat channel.
Moreover, since Vbat input contains a built-in voltage divider, it is highly suggested to disable Vbat input channel after measurement is done in order to prevent battery drain through the divider.
This commit adds logic to first check for UDP connection mode. If the UDP socket is connected, then the NULL 'to' address is ignored and saved connection address is used instead.
