Originally, for riscv big and little cores under bsp/cvitek, after generating rtthread.bin, the cvitek_bootloader tool would be used to package it and generate fip.bin and boot.sd files that can be burned into sdcard. However, the cvitek_bootloader tool repository is relatively large, and it compiles and generates firmware such as fsbl, opensbi and uboot from the source code level. And when using it, it needs to be downloaded to the bsp/cvitek directory, which will introduce pollution to source files in the RTT repository under the original working path. The new solution uses rttpkgtool, which is similar to cvitek_bootloader, but it uses prebuilt firmware, so it is very small and does not introduce pollution to the source file.
