Thanks for reviewing.

For a board to be able to benefit from flash-kernel U-Boot must:

- be capable to load and execute boot.scr
- provide the booti command
- allow the definition of the following environment variables:
  - devtype, devnum, partition
  - fdtfile
  - kernel_addr_r
  - fdt_addr_r
  - ramdisk_addr_r

In your examples above I could not find any evidence that U-Boot cannot
be configured and built to fulfill these requirements.

For instance build

make r8a77995_draak_defconfig
make menuconfig
CONFIG_ENV_IS_IN_MMC=y (this is a default value)
make -j6

Setup missing environment variables interactively and save them to MMC
and you can rely on flash-kernel for booting.

ls1088ardb_sdcard_qspi_defconfig and hikey_defconfig select

This patch is only about providing flash-kernel for the boards. It is
not about providing U-Boot configured to match flash-kernel's requirements.

I think that even for boards for which we do not provide U-Boot as a
Debian package we should allow the usage of flash-kernel without setting
up a local override for the machine database (/etc/flash-kernel/db).

Best regards
