The mainline U-Boot can create an i.MX specific firmware image (e.g. flash.bin).
For this the i.MX firmware files (DDR, HDMI) must be in the toplevel directory.

v3:
 - included the comments from Fabio
 - add Fabio's SOB

v2:
 - small changes in commit messages (thanks Stephane)
 - use "i.MX 8M" for consistency (thanks Stephane)

I've changed that to a simpler hook:

  185 ifeq ($(BR2_TARGET_UBOOT_NEEDS_IMX_FIRMWARE),y)
  186 UBOOT_DEPENDENCIES += firmware-imx
  187 UBOOT_IMX_FW_FILES = \
  188     $(if $(BR2_PACKAGE_FIRMWARE_IMX_NEEDS_HDMI_FW),signed_hdmi_imx8m.bin) \
  189     $(if $(BR2_PACKAGE_FIRMWARE_IMX_LPDDR4),lpddr4*.bin) \
  190     $(if $(BR2_PACKAGE_FIRMWARE_IMX_DDR4),ddr4*.bin)
  191
  192 define UBOOT_COPY_IMX_FW_FILES
  193     $(foreach fw,$(UBOOT_IMX_FW_FILES),\
  194         cp $(BINARIES_DIR)/$(fw) $(@D)/
  195     )
  196 endef
  197 UBOOT_PRE_BUILD_HOOKS += UBOOT_COPY_IMX_DDR_FIRMWARE
  198 endif

Applied to master with this change, thanks.

Regards,
Yann E. MORIN.
