   19: Add support for reading files from a BSD Fast File System from within U-Boot. Typically, on ARM boards where we boot NetBSD with U-Boot we require the kernel to live on an MSDOS or Linux Ext2/3/4 file-system. It would be nice if we could load a kernel directly from FFSv1 or FFSv2 instead.
   20: 
   21: This project requires access to an ARM board that is supported by mainline U-Boot and NetBSD.
   22: 
   23: **Milestones:**
   24: 
   25: * Add an ffs driver to U-Boot (read-only)
   26: * Add this new driver to existing U-Boot packages (sysutils/u-boot*) in pkgsrc
   27: * Update armv7.img to support booting directly from FFS.
   28: * Modify sysinst to allow for installation without an MSDOS partition.
   29:   * Some of this will be SoC-specific. Need to detect the SoC type and select the correct kernel/dtb and adjust partition layout to not interfere with U-Boot / SoC specific bootloaders.
   30: 
   31: **Extended goals:**
   32: 
   33: * Add write support to the U-Boot ffs driver
   34: * Submit U-Boot FFS driver for inclusion with mainline U-Boot
