2016-10-28Remove $COREBASE/LICENSE from LIC_FILES_CHKSUMOlaf Mandel
Several recipes reference the LICENSE file in their LIC_FILES_CHKSUM variable as ${COREBASE}/LICENSE. This forces distribution providers to keep this file verbatim or to overload the affected recipes. The section "Moving to the Yocto Project 1.6 Release" in the Yocto manual suggests removing the LICENSE file where possible. Remove LICENSE in cases where COPYING.MIT is also given and replace LICENSE with COPYING.MIT if the former was the only entry. All modified recipes specify LICENSE = "MIT" and none of the in-tree files specify a different license either. As the packages do not change (the license files are not contained in them), do not increase PR.

The udev initscript signals udev-cache to run by generating a new sysconf; but udev-cache now overwrites that with its own copy. To eliminate the needless sysconf generating in udev, we instead trigger udev-cache to run by touching a new file $DEVCACHE_REGEN.

2014-12-19udev-cache: replace readfiles() with cmpRichard Tollerton
Currently, udev-cache system configurations are compared as shell string variables, read into memory with the readfiles() function. This is more complex, and significantly (27-41%) slower, than comparing them using `cmp`. (Performance was verified on both Cortex-A9 and Intel Nehalem systems.) So just use cmp. This requires a few other small changes: exclude /proc/atags from CMP_FILE_LIST if it doesn't exist to avoid errors in `cat` and `cmp`. `cmp -q` doesn't exist in busybox, so instead, redirect output to /dev/null.
