  "Make a grub-efi-netboot package named NAME, which will be able to boot over
network via TFTP by accessing its files in the SUBDIR of a TFTP root directory.
This package is also able to boot from local storage devices.

A bootloader-installer basically needs to copy the package content into the
bootloader-target directory, which will usually be the TFTP root, as
'grub-mknetdir' will be invoked already during the package creation.

Alternatively the bootloader-target directory can be a mounted EFI System
Partition (ESP), or a similar partition with a FAT file system, for booting
from local storage devices.

The name of the GRUB EFI binary will conform to the UEFI specification for
removable media.  Depending on the system it will be e.g. bootx64.efi or
bootaa64.efi below SUBDIR.

The SUBDIR argument needs to be set to \"efi/boot\" to create a package which
conforms to the UEFI specification for removable media.

The SUBDIR argument defaults to \"efi/Guix\", as it is also the case for
'grub-efi-bootloader'."

Systems TS-7970 revision C board, which includes a quad core Freescale i.MX6
CPU and 2 GiB of RAM clocked at 1000MHz.  The binary U-Boot image to flash is
the @file{libexec/u-boot.imx} file.  It can be used with the @file{zImage} and
the @file{imx6q-ts7970.dtb} files provided by the
@code{linux-libre-arm-generic} image.

To flash this bootloader, write it to an SD card, then using the U-Boot serial
console:
@example
mmc dev 0
load mmc 0:1 ${loadaddr} /boot/u-boot.imx
sf probe
sf erase 0 0x80000
sf write ${loadaddr} 0x400 $filesize
@end example

The factory values of U-Boot must also be reset so that it boots using a
zImage instead of the default uImage:
@example
run clearenv
reset
@end example

@url{https://docs.embeddedts.com/TS-7970#Update_U-Boot}.")))

implementation enhanced with additional features such as booting from: a web
server via HTTP, an iSCSI SAN, a Fibre Channel SAN via FCoE, an AoE SAN, a
wireless network, a wide-area network, an Infiniband network.  It
controls the boot process with a script.  You can use iPXE to replace the
existing PXE ROM on your network card, or you can chainload into iPXE to obtain
the features of iPXE without the hassle of reflashing.")
