Since attempt[1] to embed android specific boot param into fdt bootargs, a new idea is formed as to make use of env file to contain default param value. Current code logic is already working fine, unless the priority of param at begining is higher than at tail. From env file, bootargs is treated important, and prepend at begining. So there is a need to reverse the logic, and make sure default bootargs value at the end, and let androidboot img bootargs value sit at begining.
So a new kconfig item is introduced. Once enabled, the bootargs strcat param will get reversed. Some one-liners patch is included to enable device driver for sc7180 soc. It is about iommu for usb, usb gadget vendor/product id, and abootimg dependency. Worth mentioning is as always, the EL1 jump_linux[2] logic to boot.
