[PATCH v2 0/2] tools: mkimage: cleanups + allow to create legacy image with type flat_dt

[Marc Kleine-Budde]

Hello,

the first patch cleans up the error message output if struct
image_type_params::set_header is set, the other adds support for
creating legacy images with type flat_dt.

regards,
Marc

Changes since v1:
- introduce new image type (suggested by Sean Anderson)
  instead of adding new cmd line parameter

[PATCH v2 1/2] tools: mkimage: don't print error message "Success" in case of failure

[Marc Kleine-Budde]

In case there's no struct image_type_params::set_header callback, no
"errno" will be set. Don't fail with an error message, followed by
"Success". Remove the printing of the human readable "errno" value.

[PATCH v2 2/2] tools: mkimage: add new image type "flat_dt_legacy"

[Marc Kleine-Budde]

If the user select the image type "flat_dt" a FIT image will be build.
This breaks the legacy use case of putting a Flat Device Tree into a
legacy u-boot image.

Add a new image type "flat_dt_legacy" to build a legacy u-boot image
with a "flat_dt" type.

Sean, what about this approach compared to adding the new command line
parameter?

There is already the "flat_dt" in boot/image.c, which is the "new" image
type:

> 	{	IH_TYPE_FLATDT,        "flat_dt",        "Flat Device Tree", },
[...]
>+      {	IH_TYPE_FLATDT_LEGACY, "flat_dt_legacy", "Flat Device Tree legacy Image", },

I need a legacy image, where the type is set to IH_TYPE_FLATDT. Maybe
"legacy_flat_dt" or "legacy_fdt" would be an appropriate name, too.

As this string is user facing I think it should have "legacy" in it.
I think "flat_dt" and "fdt" is just too similar and the user can't see
the difference, IMHO.
