This is a series of patches to enable chainloading LineageOS on qcom SOC. Patch #1 introduce kconfig to ignore those default value and use loadaddr instead. That workaround some androidboot image have invalid kernel/ramdisk loadaddr.
Patch #2 enable #1 for snapdragon machine. Patch #3 override qcom soc loadaddr with fastboot_addr_r as a band-aid. Casey confirmed loadaddr and kernel_addr_r are purposely set to same address for memory-constrain case. A proper fix is far from get ready so this patch can work as a band-aid for maintainer atm. Remain as unchanged to make it conditional on CONFIG_FASTBOOT is because that also imply CONFIG_ANDROID_BOOT_IMAGE set y.
