2018-07-24avb2.0: add proper dependenciesIgor Opaniuk1-0/+1
1. Since libavb library alone is highly portable, introduce dedicated Kconfig symbol for AVB bootloader-dependent operations, so it's possible to build libavb separately. AVB bootloader-dependent operations include: * Helpers to process strings in order to build OS bootargs. * Helpers to access MMC, similar to drivers/fastboot/fb_mmc.c. * Helpers to alloc/init/free avb ops. 2. Add CONFIG_FASTBOOT dependency, as fastboot buffer is re-used in partition verification operations.
