image: add support for building FIT image with filesystem Allow for single (external-data) FIT image to hold kernel, dtb and squashfs. In that way, the bootloader verifies the system integrity including the rootfs, because what's the point of checking that the hash of the kernel is correct if it won't boot in case of squashfs being corrupted? Better allow bootloader to check everything needed to make it at least up to failsafe mode. As a positive side effect this change also makes the sysupgrade process on nand potentially much easier as it is now. In short: mkimage has a parameter '-E' which allows generating FIT images with 'external' data rather than embedding the data into the device-tree blob itself. In this way, the FIT structure itself remains small and can be parsed easily (rather than having to page around megabytes of image content). This patch makes use of that and adds support for adding sub-images of type 'filesystem' which are used to store the squashfs. Now U-Boot can verify the whole OS and the new partition parsers added in the Linux kernel can detect the filesystem sub-images, create partitions for them, and select the active rootfs volume based on the configuration in FIT (passing configuration via device tree could be implemented easily at a later stage). This new FIT partition parser works for NOR flash (on top of mtdblock), NAND flash (on top of ubiblock) as well as classic block devices (ie. eMMC, SDcard, SATA, NVME, ...). It could even be used to mount such FIT images via `losetup -P` on a user PC if this patch gets included in Linux upstream one day ;) Signed-off-by: John Crispin <john@phrozen.org> Signed-off-by: Daniel Golle <daniel@makrotopia.org>

mikrotik: switch to Yafut for building MikroTik NOR images The Yafut tool now has limited capabilities for working on filesystem images stored in regular files. This enables preparing Yaffs2 images for devices with NOR flash using upstream Yaffs2 filesystem code instead of the custom kernel2minor tool. Since minimizing the size of the resulting filesystem image size is important and upstream Yaffs2 code requires two allocator reserve blocks to be available when writing a file to the filesystem, a trick is employed while preparing an OpenWRT image: the blank filesystem image that Yafut operates on initially contains two extra erase blocks that are chopped off after the kernel file is written. This is safe to do because Yaffs2 has a true log structure and therefore only ever writes sequentially (and the size of the kernel file is known beforehand). While the two extra erase blocks are necessary for writes, Yaffs2 code seems to be perfectly capable of reading back files from a "truncated" filesystem that does not contain these extra erase blocks. In terms of image size, this new approach is only marginally worse than the current kernel2minor-based one: specifically, upstream Yaffs2 code needs to write three object headers (each of which takes up an entire data chunk) when the kernel file is written to the filesystem: - an object header for the kernel file when it is created, - an object header for the root directory when the kernel file is created, - an updated object header for the kernel file when the latter is fully written (so that its new size can be recorded). kernel2minor only writes two of these headers, which is the absolute minimum required for reading the file back. This means that the Yafut-based approach causes firmware images to be at most one erase block (64 kB) larger than those created using kernel2minor, but only in the very unfortunate scenario where the size of the kernel file is really close to a multiple of the erase block size. The rest of the calculations performed when the empty filesystem image is first prepared stems from the Yaffs2 layout used by MikroTik NOR devices: each 65,536-byte erase block contains 63 chunks, each of which consists of 1024 bytes of data followed by 16-byte Yaffs tags without ECC data; each such group of 63 chunks is then followed by 16 bytes of padding, which translates to "-C 1040 -B 64k -E" in the Yafut invocation. Yaffs2 checkpoints and summaries are disabled (using Yafut's -P and -S switches, respectively) as they are merely performance optimizations that require extra storage space. The -L and -M switches are used to force little-endian or big-endian byte order (respectively) in the resulting filesystem image, no matter what byte order the build host uses. The tr invocation is used to ensure that the filesystem image is initialized with 0xFF bytes (which are an indicator of unused space for Yaffs2 code).
