[PATCH 0/3] mkimage: modify show_valid_options for usability

[Naoki Hayama]

Currently, show_valid_options() shows "Unknown ***" lines.
For example:

	$ ./tools/mkimage -A hoge
	Invalid architecture, supported are:
		Unknown architecture  Unknown architecture
		Unknown architecture  Unknown architecture
		alpha            Alpha
		arc              ARC
		arm              ARM
		arm64            AArch64
		...

It's because include/image.h must keep obsolete IDs for
backward compatibility (see comit ff87b0810753), and
show_valid_options() tries to find entry IDs which don't exist
in a category table defined in common/image.c
(in this case, uimage_arch[]).

To fix this problem, this patchset introduces checking whether
a category table has an entry ID. If an entry ID doesn't exist,
adding it to a list for output is skipped before calling qsort().
The output will be:

	$ ./tools/mkimage -A hoge
	Invalid architecture, supported are:
		alpha            Alpha
		arc              ARC
		arm              ARM
		arm64            AArch64
		...

This patchset will affect all kinds of image header categories
(-A, -C, -O and -T flags).
