Revert "image-fit: switch ENOLINK to ENOENT"

2016-09-19T14:43:12+00:00

As while I want to support OpenBSD hosts, this change broke FIT images
as in the image checking code we care about ENOLINK and on further
review we need to think about what to change ENOLINK to so we can be
sure to handle the different cases here.

This reverts commit bac17b78daceeba1af2e1d8cd204ee460c71c93a.

image-fit: switch ENOLINK to ENOENT

2016-09-07T12:49:06+00:00

ENOLINK is not required by POSIX and does not exist on OpenBSD
and likely other systems.

image-fit: fix fit_image_load() OS check

2016-09-06T17:18:19+00:00

Commit 62afc601883e788f3f22291202d5b2a23c1a8b06 introduced fpga image load via
bootm but broke the OS check in fit_image_load().

This commit removes following compiler warning:

common: image: Add support for post-processing of images

2016-08-12T13:22:18+00:00

This commit allows injecting a board/platform/device-specific post-
processing function into the FIT image data loading process, which can
include modifying the size and altering the starting source address of
an image data artifact. This might be desired to do things like strip
headers or footers attached to the images before they were packaged into
the FIT, or to perform operations such as decryption or authentication.
Introduce new configuration option CONFIG_FIT_IMAGE_POST_PROCESS to
allow controlling this feature. If enabled, a platform-specific post-
process function must be provided.

common: fit: Allow U-Boot images to be booted

2016-07-25T16:00:05+00:00

In certain circumstances it comes in handy to be able to boot into a second
U-Boot. But as of now it is not possible to boot a U-Boot binary that is inside
a FIT image, which is problematic for projects that e.g. need to guarantee a
unbroken chain of trust from SOC all the way into the OS, since the FIT signing
mechanism cannot be used.

This patch adds the capability to load such FIT images.

An example .its snippet (utilizing signature verification) might look
like the following:

images {
	firmware@1 {
		description = "2nd stage U-Boot image";
		data = /incbin/("u-boot-dtb.img.gz");
		type = "firmware";
		arch = "arm";
		os = "u-boot";
		compression = "gzip";
		load = <0x8FFFC0>;
		entry = <0x900000>;
		signature@1 {
			algo = "sha256,rsa4096";
			key-name-hint = "key";
		};
	};
};

image-fit: Don't display an error in fit_set_timestamp()

2016-05-23T15:50:18+00:00

This function returns an error code and its caller may be able to fix the
error. For example fit_handle_file() expands the device tree to fit if there
is a lack of space.

In this case the caller does not want an error displayed. It is confusing,
since it suggests that something is wrong, when it fact everything is fine.
Drop the error.
