kernel uses tmpfs as initramfs by dafault, and tmpfs allocates 1/2 of<br>
ram by default at boot time, which will be used to locate the initramfs.<br>
<br>
Set INITRAMFS_MAXSIZE to 131072K (128M) by default (ram 256M), the<br>
initramfs is small usually, for example, core-image-minimal-initramfs is<br>
about 21M (uncompressed, 17M * 1.3) by default, but if the user add a<br>
lot pkgs to initramfs, we can error and stop to let the user know ealier<br>
rather than fail to boot (e.g., OOM-killer) at boot time.<br>
