[PATCH v2] arm64: kbuild: remove compressed images on 'make ARCH=arm64 (dist)clean'

[PATCH v2] arm64: kbuild: remove compressed images on 'make ARCH=arm64 (dist)clean'

[Eugeniu Rosca]

From: Dirk Behme <dirk.behme@de.bosch.com>

Since v4.3-rc1 commit 0723c05fb75e44 ("arm64: enable more compressed
Image formats"), it is possible to build Image.{bz2,lz4,lzma,lzo}
AArch64 images. However, the commit missed adding support for removing
those images on 'make ARCH=arm64 (dist)clean'.

Fix this by adding them to the target list.
Make sure to match the order of the recipes in the makefile.

Hi,

This commit has been processed because it contains a "Fixes:" tag,

The bot has tested the following trees: v5.4.13, v4.19.97, v4.14.166, v4.9.210, v4.4.210.

v5.4.13: Build OK!
v4.19.97: Build OK!
v4.14.166: Build OK!
v4.9.210: Build OK!
v4.4.210: Failed to apply! Possible dependencies:
    f8fa70f392fa ("arm64: localise Image objcopy flags")


NOTE: The patch will not be queued to stable trees until it is upstream.

How should we proceed with this patch?

The heuristics of your scripts is correct.

Upon picking f8fa70f392fa ("arm64: localise Image objcopy flags")
first, the backporting conflict of ("arm64: kbuild: remove compressed
images on 'make ARCH=arm64 (dist)clean'") is avoided.

Shared my thoughts above. Any other input needed?
