[Buildroot] [PATCH next 1/1] configs/freescale_imx93frdm: new defconfig

[Julien Olivain]

This commit adds support for the i.MX 93 FRDM (Freedom) board.

The i.MX93 FRDM development board is a low-cost and compact
development board featuring the i.MX93 applications processor.

See: https://nxp.com/FRDM-IMX93

This defconfig is based on freescale_imx93evk_defconfig introduced
by Sébastien, in Cc.

Note: the Linux and U-Boot repositories are forks. This is because
the NXP software team did not included all the necessary i.MX93 FRDM
patches in the standard NXP i.MX BSP at the time of this commit.
Instead, patches were published in a dedicated Yocto Layer from [1].
The forks used in this defconfig are simply the repositories [2]
and [3] with patches from [1] applied on them. This is only to make this
defconfig simpler in the meantime the BSP patches are included in the
NXP BSP repositories.

Thanks to Martin Chabot for lending a board!

+**********************
+NXP i.MX 93 FRDM board
+**********************
+
+This file documents the Buildroot support for the i.MX 93 FRDM
+(Freedom) board. For more information on this board, see [1].
+
+
+Build
+=====
+
+First, configure Buildroot for the i.MX 93 FRDM board:
+
+    make freescale_imx93frdm_defconfig
+
+Build all components:
+
+    make
+
+When this command completes, the generated image containing everything
+to boot from the SD card is located in "output/images/sdcard.img".
+
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+    cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a SD card. Launch the following
+command as root:
+
+    dd if=output/images/sdcard.img of=/dev/<your-sd-device>
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/common/imx/genimage.cfg.template_imx9.
+
+
+Boot the i.MX 93 FRDM board
+===========================
+
+To boot your newly created system (refer to the i.MX 93 FRDM
+Documentation [2] for guidance):
+- insert the SD card in the SD slot (P13) of the board;
+- Configure the SW1 boot switches as follows:
+  SW1: 1100 SW1[1-4] ("USDHC2 4-bit SD3.0" Boot Mode)
+- connect a USB Type-C cable into the P16 Debug USB Port and connect
+  using a terminal emulator at 115200 bps, 8n1;
+- power on the board by connecting a USB Type-C cable into the P1
+  Power USB Port.
+
+Note 1: the board boot switches default configuration is:
+SW1: 0100 SW1[1-4] ("USDHC1 8-bit eMMC 5.1" Boot Mode)
+and the board is also pre-flashed with a reference Linux demo
+image. It is important to change the boot config switches to make
+sure the system will boot on the SD Card.
+
+Note 2: the debug USB connector presents 2 UARTs (for example
+/dev/ttyACM[0-1]), the Cortex-A55 UART should be the 1st one (in the
+previous example, /dev/ttyACM0). Refer to the documentation [2] for
+more details.
+
+Enjoy!

It would be great to get this board supported in upstream U-Boot and kernel.

I can help with that if someone sends me this board.
