AXFS prebuilt image
HiIn the BSP V 1.2.0, we see that while SquashFS is built using build.sh for AXFS only a prebuilt image isused.Any specific reason why this is not being built?ThanksShankar

squashfs and axfs are read-only file system. There is no R/W option.squashfs is a compressed file system, so the flash images are smaller and reading out blocks are quick, but all code blocks need to...
