First boot after a factory reset does not enter the regular code path because factory-config essentially becomes the startup-config. So it left the status LED blinking. Follow-up to a7c95cd. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
A cut down LAN969x reference design, same switch core as the EV23X71A in a LAN9696TSN. Novarq's device tree is cherry-picked as is into the kkit kernel branch, with one commit on top that drops what 6.18 lacks (QSPI, tmon fan PWM and its cooling maps); revert it at the next LTS kernel. The patches came in with the 6.18.53 bump. The copper ports are wired backwards within each QSGMII quad, so the rename rule follows the device tree labels rather than probe order. No genimage.cfg.in yet, the board netboots with the vendor bootloader and provision-tactical lays out the eMMC. It grows Env to 4 MiB: the vendor U-Boot writes its redundant environment copy at 0x10300000, the end of a 2 MiB Env, which is how aux kept getting destroyed.

The Tactical 1000's vendor U-Boot has neither BLKMAP, SquashFS nor sysboot, so it cannot boot rootfs.itb, and it stays until Infix has a bootloader for the board. Pack kernel, rootfs and every device tree in the build into one FIT it can start with a single bootm, plus a boot script to hand out over DHCP for the test system. One configuration per device tree, so one image serves every board in the build. The device trees go last: U-Boot grows the selected one in place for bootargs and ramdisk bounds, and ahead of the ramdisk that overrun kills the kernel before earlycon. The kernel is a gzipped kernel_noload so nothing in the image depends on a memory map, and the rootfs copy of it in /boot is dropped, 13 MiB the FIT already carries.

The part number decides whether the driver offers PTP and PSFP, and is the only thing that tells the Laguna boards apart, so it is worth having before Linux is up. Trim some scene-setting prose while here. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
Only Trusted Firmware differs between the LAN969x boards, for the DDR parameters; U-Boot and its environment do not. Move them out of the EV23X71A directory and pick the device tree at boot from GCB_CHIP_ID, since neither TF-A's board-number nor U-Boot's GPIO strap read tells the boards apart. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
BL2 carries the DDR parameters, 2 GiB here against 896 MiB on the EV23X71A, so the board needs a FIP of its own. Novarq's platform is carried as a patch on our Trusted Firmware pin rather than built from their fork, which is 23 commits behind it and lacks the regenerated lan969x DDR4 timings and the ECDSA fixes. Not yet booted. Recovery from a FIP that hangs is the TF-A monitor, selected over the MCP2200 on the console port. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
The markers that stop the first-boot resize from running again live in aux, and nothing checked that aux was mounted before rewriting the partition table and rebooting. A disk with a var partition but no aux filesystem, a half provisioned eMMC say, looped forever on stage 1. Bail out and boot without /var instead. The progress messages said sdcard on every board, eMMC included, as nothing tells the two apart. Name neither. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
GitHub's image proxy gets a 503 when it fetches the badge from bitsign.se, so the logo stopped showing in the README. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
