[Buildroot] [PATCH v2] configs/imxrt1050-evk: New defconfig

[Jesse Taube <mr.bossman075@gmail.com>]

Add defconfig for imxrt1050-evk is a development board from NXP.

The i.MXRTxxxx family spreads from i.MXRT1020 to i.MXRT1170 with the
first one supporting 1 USB OTG & 100M ethernet with a cortex-M7@500Mhz
up to the latter with i.MXRT1170 with cortex-M7@1Ghz and
cortex-M4@400Mhz, 2MB of internal SRAM, 2D GPU, 2x 1Gb and
1x 100Mb ENET. The i.MXRT family is NXP's answer to STM32F7xx, as it
uses only simple SDRAM, it gives the chance of a 4 or less layer PCBs.
Seeing that these chips are comparable to the STM32F7xxs which have
buildroot ported to them it seems reasonable to add support for them.

+NXP i.MXRT1050 EVK board
+---------------------
+
+To build a minimal support for this board:
+
+$ make imxrt1050-evk_defconfig
+$ make
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be flashed into the SD card:
+
+$ dd if=output/images/sdcard.img of=/dev/sdX
+Where 'sdX' is the device node of the uSD.
+
+Jumper settings:
+
+   SW7: 1 0 1 0
+
+Where 0 means bottom position and 1 means top position (from the
+switch label numbers reference).
+
+Connect the USB cable between the EVK and the PC for the console.
+
+Insert the micro SD card in the board, power it up and U-Boot messages should come up.
