This includes the VBE ABrec (A/B/recovery) implementation as well as a number of patches needed to make it work:
- marking some code as used by SPL_RELOC - selection of images from a FIT based on the boot phase - removal of unwanted hash code which increases code-size too much - a few Kconfig-related additions for VPL
Note: The goal for the next series (part H) is to enable VBE on rk3399-generic, i.e. able to boot on multiple rk3399-based boards with only the TPL phase being different for each board.
Simon Glass (19): mbedtls: Add SHA symbols for VPL sandbox: Update sandbox_vpl to select sha1 and sha256 mmc: Allow controlling DM_MMC for VPL builds lib: Allow crc16 code to be dropped spl: Adjust debugging and xPL symbols spl: Avoid including hash algorithms which are not wanted spl: Support selecting images based on phase in simple FIT vbe: Support selecting images based on phase in FIT spl: Allow spl_load() to be controlled in any xPL phase spl: Provide a way to mark code needed for relocation lib: Mark crc8 as relocation code lib: Mark lz4 as relocation code lib: Mark memcpy() and memmove() as relocation code lib: Mark gunzip as relocation code vbe: Support providing a linker script vbe: Provide VPL binman-symbols for the next phase vbe: Tidy up a few comments vbe: Allow VBE to disable adding loadables to the FDT vbe: Add an implementation of VBE-ABrec
