Browse Source 
The patch:
* bumps Linux kernel to version 6.18.8
* bumps U-Boot to version 2026.01
* forces check hashes
* create a board/freescale/imx6ull-evk folder dedicated to upstream Linux
  and U-Boot to ease maintainance.
* clean up both imx6ullevk and imx6ull-evk readme.txt files

****************************
Freescale i.MX6ULL EVK board
****************************
This file documents the Buildroot support for the Freescale i.MX6ULL EVK board
using Upstream U-Boot and Linux.
Build
=====
First, configure Buildroot for your i.MX6ULL EVK board:
In order to do so issue:
make imx6ullevk_defconfig
Build all components:
make
You will find in output/images/ the following files:
- boot.vfat
- imx6ull-14x14-evk.dtb
- rootfs.ext2
- rootfs.ext4
- rootfs.tar
- sdcard.img
- u-boot.bin
- u-boot-dtb.imx
- zImage
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.
Boot the i.MX6ULL EVK board
===========================
To boot your newly created system (refer to the i.MX 6ULL EVK Quick Start Guide [1] for guidance):
- insert the SD card in the micro SD slot of the board;
- put a micro USB cable into the Debug USB Port and connect using a terminal
emulator at 115200 bps, 8n1;
- power on the board.
Enjoy!

=====
First, configure Buildroot for your i.MX6ULL EVK board:
In order to do so there are two supported options:
In order to do so issue:
make freescale_imx6ullevk_defconfig
if you plan to use NXP provided U-Boot and kernel.
or
make imx6ullevk_defconfig
if you plan to use mainline U-Boot and mainline kernel.
