image.bbclass: check INITRAMFS_MAXSIZE
Usually, the initramfs' maxsize can be 1/2 of ram size since modern kernel uses tmpfs as initramfs by dafault, and tmpfs allocates 1/2 of ram by default at boot time, which will be used to locate the initramfs. Set INITRAMFS_MAXSIZE to 131072K (128M) by default (ram 256M), the initramfs is small usually, for example, core-image-minimal-initramfs is about 21M (uncompressed, 17M * 1.3) by default, but if the user add a lot pkgs to initramfs, we can error and stop to let the user know ealier rather than fail to boot (e.g., OOM-killer) at boot time. Please see the bug for more info: https://bugzilla.yoctoproject.org/show_bug.cgi?id=5963 [YOCTO #5963] (From OE-Core rev: 155ba626b46bf71acde6c24402fce1682da53b90) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
