# This is a boot script for U-Boot
# Generate boot.scr:
# mkimage -c none -A arm -T script -d boot.cmd boot.scr
# For initrd, when using a file override:
# mkimage -A arm -O linux -T ramdisk -d initrd.img rootfs.cpio.gz.u-boot
# Kernel "Image" file must be of EFI type:
# - Get vmlinuz from Ubuntu rootfs and uncompress
# system.dtb is a normal dtb file

# Here is the Kria board support list:
#
# Kria board | DTB Name |
# :----------------------------- | :---------------------------- |
# Revision A KR Carrier Card | smk-k26-revA-sck-kr-g-revA |
# Revision B/1 KR Carrier Card | smk-k26-revA-sck-kr-g-revB |
# Revision A/Z KV Carrier Card | smk-k26-revA-sck-kv-g-revA |
# Revision B/1 KV Carrier Card | smk-k26-revA-sck-kv-g-revB |
# Revision A KD Carrier Card | smk-k24-revA-sck-kd-g-revA |
#
#
# Variables expected to be in the environment:
#
# Variable | Description |
# :------------- | :------------------------------------------------------------------------------------ |
# card1_name | Holds the information about the carrier card configuration (utilized for Kria family) |
# boot_targets | Includes the list of devices that can be used to look for image boot |

# Local Variables:

# Variable | Description |
# :-------------- | :------------------------------------------------------------------------------------ |
# kria | Holds the information about the type of the board in Kria family. | \
# | Possible values when it is initialized: "KD", "KR", "KV" |
