This adds: (Aligned) load address calculations This will remove the need to update any kernel_load_addr_r or ramdisk_addr_r in case kernel image increases. Calculation is based on either Flat kernel image image_size + text_offset as specified in the vmlinux(/Image) header info Compressed kernel image filesize (vmlinuz/zImage) Clear warnings to user in case files are not found, not able to load or application failed. Merge of armbianEnv.txt kernel options was attempted for sunxi, mvebu and rockchip64. DT folder determination based on sunxi approach. DT file determination based on sunxi approach. Compat with /boot/dtb/fdtfile.dtb and /boot/dtb/vendor/fdtfile.dtb. Simplified some constructs by assuming U-Boot has successfully sourced us with a set of pre-set variables, like ${prefix} ${devtype} etc. Actively set the ${kernel_comp_*} parameters based on calculations of load addresses. Ability to select different kernel/initrd by setting kver in armbianEnv.txt Also: Any warning or error includes a 10 second delay to make sure the user is able to see and read them. Any "informative" message added by the bootscript can be silenced by setting verbosity to 0 Attempted to make the bootscript 'reentrant' in away: all variables required for proper (re)execution are set, which should allow for the entire bootscript to be re-run on a next boot_target. All variables used in for-loops are actively cleared from the environment to ensure for loops work as expected. Any pre-set variable that might be used in next boot_target will be reset whenever necessary. Documentation summary for feature / change [ ] short description (copy / paste of PR title) [x] summary (description relevant for end users) Load address calculation can be disabled by adding load_addr_calc=off to armbianEnv.txt Load address calculation OBOE avoidance can be disabled by adding align_overlap_oboe_avoidance=off to armbianEnv.txt User can set custom fdtdir and fdtfile in armbianEnv.txt, but make sure to only specify DT filename in fdtfile. fdtdir will be used to both load DT, DT overlays and fixup scripts [ ] example of usage (how to see this in function) How Has This Been Tested?
