* mpc85xx: Drop pci aliases to avoid domain changesMartin Kennedy2022-09-021-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of upstream Linux commit 0fe1e96fef0a ("powerpc/pci: Prefer PCI domain assignment via DT 'linux,pci-domain' and alias"), the PCIe domain address is no longer numbered by the lowest 16 bits of the PCI register address after a fallthrough. Instead of the fallthrough, the enumeration process accepts the alias ID (as determined by `of_alias_scan()`). This causes e.g.: 9000:00:00.0 PCI bridge: Freescale Semiconductor Inc P1020E (rev 11) 9000:01:00.0 Network controller: Qualcomm Atheros AR958x 802.11abgn ... to become 0000:00:00.0 PCI bridge: Freescale Semiconductor Inc P1020E (rev 11) 0000:01:00.0 Network controller: Qualcomm Atheros AR958x 802.11abgn ... ... which then causes the sysfs path of the netdev to change, invalidating the `wifi_device.path`s enumerated in `/etc/config/wireless`. One other solution might be to migrate the uci configuration, as was done for mvebu in commit 0bd5aa89fcf2 ("mvebu: Migrate uci config to new PCIe path"). However, there are concerns that the sysfs path will change once again once some upstream patches[^2][^3] are merged and backported (and `CONFIG_PPC_PCI_BUS_NUM_DOMAIN_DEPENDENT` is enabled). Instead, remove the aliases and allow the fallthrough to continue for now. We will provide a migration in a later release. This was first reported as a Github issue[^1].

* mpc85xx: add support for OCEDO PandaDavid Bauer2019-01-261-0/+264
CPU: FSL P1020 (2x 800MHz E500 PPC) RAM: 1GB DDR3 FLASH: 256MiB NAND WiFi: 2x Atheros AR9382 2x2:2 abgn ETH: 2x BCM54616S - 1x BCM53128 8-port switch LED: 5x LEDs (Power, WiFi1, WiFi2, N/D, SYS) BTN: 1x RESET Installation ------------ 1. Download initrams kernel image, dtb binary and sysupgrade image. 2. Place initramfs kernel into tftp root directory. Rename to "panda-uimage-factory". 3. Place dtb binary into tftp root directory. Rename to "panda.fdt". 4. Start tftp server on 192.168.100.8/24. 5. Power up the device with the reset button pressed. It will download the initrams and dtb via tftp and boot into OpenWRT in RAM. 6. SSH into the device and remove the factory partitions. > ubirmvol /dev/ubi0 --name=kernel1 > ubirmvol /dev/ubi0 --name=rootfs1 > ubirmvol /dev/ubi0 --name=devicetree1 You will have around 60 MiB of free space with that. You can also delete "kernel2", "devicetree2", "rootfs2" and "storage" respectively in case you do not want to go back to the vendor firmware. 7. Modify the U-Boot bootcmd to allow for booting OpenWRT > fw_setenv bootcmd_owrt "ubi part ubi && ubi read 0x1000000 kernel && bootm 0x1000000" > fw_setenv bootargs_owrt "setenv bootargs console=ttyS0,115200 ubi.mtd=3,2048" > fw_setenv bootcmd "run bootargs_owrt; run bootcmd_owrt" 8. Transfer the sysupgrade image via scp into the /tmp directory. 9. Upgrade the device > sysupgrade -n /tmp/<imagename> Signed-off-by: David Bauer <mail@david-bauer.net>
