This patch updates the mksunxiboot tool to optionally add the default device tree name string to the SPL header. This information can be used by the firmware upgrade tools to protect users from harming themselves by trying to upgrade to an incompatible bootloader. The primary use case here is a non-removable bootable media (such as NAND, eMMC or SPI flash), which already may have a properly working, but a little bit outdated bootloader installed. For example, the user may download or build a new U-Boot image for "Cubieboard", and then attemept to install it on a "Cubieboard2" hardware by mistake as a replacement for the already existing bootloader. If this happens, the flash programming tool can identify this problem and warn the user. The size of the SPL header is also increased from 64 bytes to 96 bytes to provide enough space for the device tree name string.
