Fixes [YOCTO #1852] The bootimg class wasn't accounting for non-trivial amount of space required by the directory entries and FATs for the FAT filesystem. This patch attempts to make an accurate prediction of FAT overhead and adjusts the image size accordingly. It assumes no more than 16 directory entries per directory (which fit in a single sector). It also assumes 8.3 filenames. With the ceiling functions rounding up to full sectors and tracks, these assumptions seem reasonable. In order to ensure the calculations are accurate, this patch forces the FAT size to 32, rather than allowing mkdosfs to automatically select 12, 16, or 32 depending on the image being built. Tested by setting BOOTIMG_EXTRA_SPACE=0 and building core-image-minimal and core-image-sato for fri2-noemgd from meta-intel.

README
Poky ==== Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration. Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way. As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project. The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/community/documentation For information about OpenEmbedded see their website: http://www.openembedded.org/
