In order to build a kernel with one of these configs the user should do the following: 1. Give the appropriate board dts file to be used by either: 1.1. edit the SoC kernel config required (e.g., MT7620A_FDT) and include the required FDT_DTS_FILE makeoption; or 1.2. simply supply FDT_DTS_FILE="xx.dts" on the command line when building the kernel Of course, the user can also create a completely new kernel config to match the desired board and include the SoC kernel config from within it. If required, edit the MEDIATEK config file, which includes optional drivers and comment out the unneeded ones. 2.1. this would only make sense if kernel size is a concern. Even if we build the kernel with all drivers, if we lzma it and package it as a uImage, its size is still around 1.1MiB. The user will have to choose a dts file (or create a new one) from sys/gnu/dts/mips , where all Mediatek/Ralink dts files will be imported via a later revision.

# Support geom_uzip(4) compressed disk images
Modularize xz. Embedded lzma decompression library becomes a module usable by other consumers, in addition to geom_uzip. Most important code changes are - removal of XZ_DEC_SINGLE define, we need the code to work with XZ_DEC_DYNALLOC; - xz_crc32_init() call is removed from geom_uzip, xz module handles initialization on its own. xz is no longer embedded into geom_uzip, instead the depend line for the module is provided, and corresponding kernel option is added to each MIPS kernel config file using geom_uzip. The commit also carries unrelated cleanup by removing excess "device geom_uzip" in places which were missed in r344479.
