apm821xx: build squashfs-rootfs images for the MBL This patch adds support for squashfs as the root filesystem. advantages: - migrate from a existing -ext4 installation and back with the sysupgrade utility - existing partition layout will not be lost during switch - slightly smaller image size as compared to the -ext4 image. disadvantages: - needs f2fs + tools. This is because fstools rootdisk.c decides based on the partition size (currently root partitions > 100 MiB) f2fs is used as the rootfs_data filesystem. - rootfs_data is placed into the rootfs partition after the squashfs. This makes it difficult for tools that expect a /dev/sda${X} device. It also makes it difficult for data recovery tools as they might not expect to find a embedded partition or will be slightly confused. ... or will not support f2fs. For people with existing build configurations: make sure to include mkf2fs and f2fsck packages into the image. Otherwise the new -squashfs image will only boot from the ram-overlay. Note: All overlay data (configurations/all installed packages/...) will be placed in inside the rootfs partition (i.e. /dev/sda2) just after the squashfs image.

apm821xx: MBL: load kernel/dtb from SATA 0:1 first This remedies an issue with the MBL Duo if both disks are inserted and contain OpenWrt. kernel and dtb would be loaded from SATA 1:1 while rootfs (/dev/sda2) would be mounted on SATA 0:1. Such a mix&match would obviously only work if both OpenWrt versions/ builds are identical, and especially fail after sysupgrade upgraded the system disk on SATA 0:1. The fallback to SATA 1:1 needs to be kept for MBL Single (only has SATA 1:1) and MBL Duo with one disk inserted on SATA 1:1. To speed up booting in those cases, the unneccesarily doubled "sata init" will only be called once. (In theory it could be omitted completely since the on-flash boot script already initializes SATA to load the on-disk boot script.) Tested on MBL Duo (all possible combination of disks) and MBL Single Acked-by: Christian Lamparter <chunkeey@gmail.com> Signed-off-by: Freddy Leitner <hello@square.wf> 2018-08-28 18:47:58 +00:00			`setenv load_part1 'ext2load sata 0:1 ${kernel_addr_r} /boot/uImage; ext2load sata 0:1 ${fdt_addr_r} /boot/apollo3g.dtb'`

apm821xx: add support for the Western Digital MyBook Live Series Hardware Highlights: This patch adds support for Western Digital MyBook Live Series: CPU: AMCC PowerPC UNKNOWN (PVR=12c41c83) at 800 MHz (PLB=200, OPB=100, EBC=100 MHz) 32 kB I-Cache 32 kB D-Cache, 256 kB L2-Cache, 32 kB OnChip Memory Board: Apollo-3G - APM82181 Board, 1*SATA DRAM: 256 MB (2x NT5TU64M16GG-AC) FLASH: 512 kB (SST 39VF040) Ethernet: 1xRGMII - 1 Gbit - Broadcom PHY BCM54610 WARNING: The serial port needs a TTL/RS-232 v3.3 level converter! The MyBook Live Duo additionally features a 1x USB 2.0 host port and can support a second hard-drive. This target produces two images for a target. 1. ext4 image The extracted/raw image can be directly installed on the internal HDD via "dd if=img.ext4 of=/dev/sdX". This can either be done in place with the stock MyBook Live firmware via ssh. Or by removing the HDD and writing the image with a different PC. The the compressed images are useful for sysupgrade. 2. recovery.tar image for TFTP and Serial. extract the recovery.tar to a TFTP server directory. On the MyBook Live (Duo) serial port - Hit Enter during u-boot and insert: # setenv serverip 192.168.1.254; setenv ipaddr 192.168.1.1; run net_self Where 192.168.1.254 is your TFTP server.
