* mpc85xx: fix incorrect CPU node / propertiesDavid Bauer2023-04-081-2/+8
| | | | | | | This adds properties normally filled by U-Boot. Also it fixes the node name, which is incorrectly referring to a P1010 core. Signed-off-by: David Bauer <mail@david-bauer.net>
* mpc85xx: add localbus frequency for WS-AP3825iDavid Bauer2023-04-081-0/+4
| | | | | | This is normally filled by U-Boot. Signed-off-by: David Bauer <mail@david-bauer.net>
* mpc85xx: add linux,stdout-path for WS-AP3825iDavid Bauer2023-04-081-0/+1
| | | | | | | This is normally filled by U-Boot. Prevents double-printing of early console messages. Also enables debug-output by the zImage wrapper. Signed-off-by: David Bauer <mail@david-bauer.net>
* mpc85xx: poll PHY statusDavid Bauer2023-03-201-2/+2
| | | | | | | | | | Disable interrupts for the eth-PHYs, as the interrupts are either not firing or lost within the stack. Switch to polling the PHY status in the meantime until a proper fix is implemented. Ref: https://github.com/openwrt/openwrt/issues/12192 Signed-off-by: David Bauer <mail@david-bauer.net>
* mpc85xx: use bootwrapper for ws-ap3825iDavid Bauer2023-03-201-0/+48
| | | | | | | | | | | | | | | The boot-procedure for the Extreme WS-AP3825I is vfragile to put it mildly. It does not relocate the FDT properly. It currently exercises every step manually as well as coming with a pre-padded dtb. Use the PowerPC bootwrapper code for legacy platforms with a pre-filles DTS instead. We still need to ship a fit image to not break the fdt resize / relocate instructions on existing boards. This does not require adapting the U-Boot bootcommand.

* mpc85xx: Make AP3825i boot env partition writableMartin Kennedy2022-09-111-2/+0
| | | | | | | | | | | | | | | End-users may need to be able to rewrite u-boot configuration on the WS-AP3825i, which has had repeated issues with the exact configuration of u-boot, e.g. commit 1d06277407 ("mpc85xx: Fix output location of padded dtb") (alongside other failures documented for example in this post[^1] from the main AP3825i porting thread). To assist with this, remove the `read-only` property from the u-boot configuration partitions cfg1 and cfg2.

* mpc85xx: Drop pci aliases to avoid domain changesMartin Kennedy2022-09-021-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: define reset-delay for WS-AP3825i eth PHYDavid Bauer2022-04-261-0/+4
| | | | | | | | | | | | The WS-AP3825i uses Atheros PHYs which according to the datasheet require the reset to be asserted for at least 1 ms. This fixes broken eth1 upon soft-reboot. eth0 is no affected, as the ifup / ifdown cycle in preinit prevents this issue from happening when the system is ready.

* mpc85xx: overhaul WS-AP3825i LED setupDavid Bauer2022-03-241-12/+12
| | | | | | | | | | | | As the LED controller is working now, we can make good use of the LEDs now. - Drop the model-name prefix - Rename eth0 / eth1 LEDs to LAN1 / LAN2, as they are labeled as such on the casing - Enable wired LEDs in userspace Signed-off-by: David Bauer <mail@david-bauer.net>
* mpc85xx: move Extreme WS-AP3825i GPIO extenderDavid Bauer2022-03-241-23/+25
| | | | | | | Move the GPIO extender to the SoC node. Otherwise, the legacy PowerPC init code will not populate the BUS and thus never probe spi-gpio. Signed-off-by: David Bauer <mail@david-bauer.net>

Hardware: - SoC: Freescale P1020 - CPU: 2x e500v2 @ 800MHz - Flash: 64MiB NOR (1x Intel JS28F512) - Memory: 256MiB (2x ProMOS DDR3 V73CAG01168RBJ-I9H 1Gb) - WiFi1: 2.4+5GHz abgn 3x3 (Atheros AR9590) - Wifi2: 5GHz an+ac 3x3 (Qualcomm Atheros QCA9890) - ETH: 2x PoE Gigabit Ethernet (2x Atheros AR8035) - Power: 12V (center-positive barrel) or 48V PoE (active or passive) - Serial: Cisco-compatible RJ45 next to 12V power socket (115200 baud) - LED Driver: TI LV164A - LEDs: (not functioning) - 2x Power (Green + Orange) - 4x ETH (ETH1 + ETH2) x (Green + Orange) - 2x WiFi (WiFi2 + WiFi1) Installation: 1. Grab the OpenWrt initramfs <openwrt-initramfs-bin>, e.g. openwrt-mpc85xx-p1020-extreme-networks_ws-ap3825i-initramfs-kernel.bin. Place it in the root directory of a DHCP+TFTP server, e.g. OpenWrt `dnsmasq` with configuration `dhcp.server.enable_tftp='1'`. 2. Connect to the serial port and boot the AP with options e.g. 115200,N,8. Stop autoboot in U-Boot by pressing Enter after 'Scanning JFFS2 FS:' begins, then waiting for the prompt to be interrupted. Credentials are identical to the one in the APs interface. By default it is admin / new2day: if these do not work, follow the OEM's reset procedure using the reset button. 3. Set the bootcmd so the AP can boot OpenWrt by executing: ```uboot setenv boot_openwrt "cp.b 0xEC000000 0x2000000 0x2000000; interrupts off; bootm start 0x2000000; bootm loados; fdt resize; fdt boardsetup; fdt chosen; bootm prep; bootm go;" setenv bootcmd "run boot_openwrt" saveenv ``` If you plan on going back to the vendor firmware - the bootcmd for it is stored in the boot_flash variable. 4. Load the initramfs image to RAM and boot by executing ```uboot setenv ipaddr <ipv4 client address>; setenv serverip <tftp server address>; tftpboot 0x2000000 <openwrt-initramfs-bin>; interrupts off; bootm start 0x2000000; bootm loados; fdt resize; fdt boardsetup; fdt chosen; bootm prep; bootm go; ``` 5. Make a backup of the "firmware" partition if you ever wish to go back to the vendor firmware. 6. Upload the OpenWrt sysupgrade image via SCP to the devices /tmp folder. 7. Flash OpenWrt using sysupgrade. ```ash sysupgrade /tmp/<openwrt-sysupgrade-bin> ``` Notes: - We must step through the `bootm` process manually to avoid fdt relocation. To explain: the stock U-boot (and stock Linux) are configured with a very large CONFIG_SYS_BOOTMAPSZ (and the device's stock Linux kernel is configured to be able to handle it). The U-boot version predates the check for the `fdt_high` variable, meaning that upon fdt relocation, the fdt can (and will) be moved to a very high address; the default appears to be 0x9ffa000. This address is so high that when the Linux kernel starts reading the fdt at the beginning of the boot process, it encounters a memory access exception and panics[5]. While it is possible to reduce the highest address the fdt will be relocated to by setting `bootm_size`, this also has the side effect of limiting the amount of RAM the kernel can use[3]. - Because it is not relocated, the flattened device tree needs to be padded in the build process to guarantee that `fdt resize` has enough space. - The primary ethernet MAC address is stored (and set) in U-boot; they are shimmed into the device tree by 'fdt boardsetup' through the 'local-mac-address' property of the respective ethernet node, so OpenWrt does not need to set this at runtime. Note that U-boot indexes the ethernet nodes by alias, which is why the device tree explicitly aliases ethernet1 to enet2. - LEDs do not function under OpenWrt. Each of 8 LEDs is connected to an output of a TI LV164A shift register, which is wired to GPIO lines and operates through bit-banged SPI. Unfortunately, I am unable to get the spi-gpio driver to recognize the `led_spi` device tree node at all, as confirmed by patching in printk messages demonstrating spi-gpio.c::spi_gpio_probe never runs. It is possible to manually articulate the shift register by exporting the GPIO lines and stepping their values through the sysfs. - Though they do not function under OpenWrt, I have left the pinout details of the LEDs and shift register in the device tree to represent real hardware. - An archive of the u-boot and Linux source for the AP3825i (which is one device of a range of devices code-named 'CHANTRY') be found here[1]. - The device has an identical case to both the Enterasys WS-AP3725i and Adtran BSAP-2030[2] (and potentially other Adtran BSAPs). Given that there is no FCC ID for the board itself (only its WLAN modules), it's likely these are generic boards, and even that the WS-AP3725i is identical, with only a change in WLAN card. I have ordered one to confirm this. - For additional information: the process of porting the board is documented in an OpenWrt forum thread[4].
