[v5] configs/imxrt1050-evk: New defconfig

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

Giulio and I worked on Linux and U-boot for this board. And now I'm
adding support for the new board in Buildroot.

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.

Here you've missed the changelog.
Also please set the V4 patch as superseded in Patchwork.

Here you must specify:
# Toolchain
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_6_1=y

otherwise the latest Linux Headers will be picked, and once version 6.2
will come out the headers will be unaligned with the Linux version.

Have you tried to build the imxrt1050-evk_defconfig using
buildroot/utils/docker-run ?

Using that I've found you also need to add:
BR2_PACKAGE_HOST_DOSFSTOOLS=y
BR2_PACKAGE_HOST_MTOOLS=y

I've retested on the board and it works good except the points above.
So with those 3 options enabled you can add:

I wait for V6.
Remember to set as superseded this V5 patch too once you've sent the V6.

Thank you!
Kind regards
