At the moment the padding steps are hardcoded. Especially images for
devices with a 4K sector size can be unnecessarily bloated using the
hardcoded padding steps.
It has been observed that 192Kb of padding was added to the image of a
4MB device, albeit due to the 4K sector size the minimum required extra
padding for the jffs2 rootfs_data is 20Kb.
In worst case it means that the image-size check could fail albeit
there is enough space for all selected packages
For device build code not exposing the blocksize, use the hardcoded
padding further on.

Allows to use the same unit for all definitions of the blocksize to be
consistent regardless of the used filesystem.

A few linux BSP's create a manifest file of installed packages for a given
target in order to help them understand exactly what's on their images. Create
one here as well as a build artifact since many users have an affinity to
prune down on packages to save valuable flash space.

1004kc is just a SMP capable 34kc, and GCC treats 24kc and 34kc exactly
the same and will generate identical code, so there is no need to tune
to 1004kc instead of 24kc.

Refresh patches for all targets that support kernel 4.4.
Compile-tested on all targets that use kernel 4.4 and aren't marked broken.
Runtime-tested on ar71xx, octeon and x86/64.

Pass KERNEL_FILE_DEPENDS to rdep instead of PKG_FILE_DEPENDS, which is
empty. Also don't pass $(CURDIR) as the directory to timestamp, as it
would also pick up non kernel related changes like image building code.
Should fix kernel being rebuild for unrelated changes, as well as not
being rebuild for changes in target/linux/generic.
Fixes: 22ef1c83b3 ("kernel: make the kernel build auto-clean the build dir like package build")

When the kernel build picks up a localversion file in the source tree,
that string is unconditionally appended to LOCALVERSION and affects the
uname string.
Make sure to delete any such file.

When building the kernel from a git repository, the kernel build appends
either a + or a short commit hash to localversion.
This behaviour can be prevented by passing the empty LOCALVERSION variable
to make.

Similar how we fix the file times in the filesystems, fix the build time
of the kernel, and make the build number static. This should allow the
kernel build to be reproducable when combined with setting the
KERNEL_BUILD_USER and _DOMAIN in case of different machines.
The reproducability only applies to non-initramfs kernels, those still
require additional changes.

Since the only difference between 24Kec and 24Kc is the addition of DSP
ASE support, and we don't use it anymore, there is no need to keep 24Kec
as a separate cpu type.

There does not seem to be any meaningful difference in generated code.
This will save some time and space on snapshot builds

when building kernel modules.
