tool: create_uboot To make the creation of a bootstrap medium for most ARM platforms more comfortable this tool shall bundle all the different U-Boot source states, patches, and MMC preparation rules that we gathered over the year for that purpose. As input, the tool merely needs the targeted platform (analogous to the platform parameter of 'create_builddir'). By now, 'hw_wand_quad' is the only supported platform. Further platforms can be added successively. As output, the tool creates a head image file of small size (8MiB) that can be copied (dd) with offset 0 to the MMC. Fixes #1730
