[Buildroot] [PATCH 1/2] package/freescale-imx: Allow firmware installation on i.MX93

[Buildroot] [PATCH 1/2] package/freescale-imx: Allow firmware installation on i.MX93

[Fabio Estevam]

Currently, the LPDDR firmware binaries do not get installed into the
U-Boot mainline directory, causing U-Boot build to fail for i.MX93.

Fix this problem by expanding the BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW
checks to also take BR2_PACKAGE_FIRMWARE_IMX_NEEDS_DDR_FW_IMX9 into account.

+NXP i.MX93 EVK
+==============
+
+This is a Buildroot target for building an image for the imx93-evk
+board using upstream components: TF-A, U-Boot and kernel.
+
+How to build it
+===============
+
+Configure Buildroot and build it:
+
+  $ make imx93-evk_defconfig
+  $ make
+
+Flashing the SD card image
+==========================
+
+Copy the sdcard.img file into the SD card:
+
+  $ sudo dd if=output/images/sdcard.img of=<your-sd-device>; sync
+
+
+Booting the board
+=================
+
+To boot your newly created system:
+
+- Insert the SD card in the MicroSD slot of the board.
+- Connect a serial to USB cable to the DBG port.
+- Open a terminal on the ttyUSB2 port. For example: sudo picocom -b 115200 /dev/ttyUSB2
+- Power on the board.

With that changes, the user can choose DDR on i.MX9{1,3} systems whereas 
only LPDDR is supported. The DDR3 and DDR4 options should be hidden on 
i.MX93.

Good catch. I will work on a patch to hide DDR3 and DDR4 options for i.MX93.
