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 0bd5aa89fc ("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].

This commit removes the target-specific diag.sh script. This way, the
generic one is used for the target, which uses DT-aliases to specify the
LEDs used.
This way, we are also able to use different LEDs to indicate different
states. We use green status LEDs for indicating boot and a running
system. Where possible, the red status LED is used to indicate failsafe
mode and a running upgrade.

Installation
============
1. Power on the device while attached to the Console port.
2. Halt the U-Boot by pressing Enter when prompted.
3. Set the correct bootcmd for booting OpenWRT:
> setenv bootargs_owrt "setenv bootargs console=ttyS0,115200"
> setenv bootcmd "run bootargs_owrt;
nand read 0x1000000 0x300000 0x800000;
bootm 0x1000000;"
> saveenv
5. Rename OpenWRT initramfs image to 'kernel.bin' and place it in a
TFTP server root-directory served on 192.168.1.2/24. Connect your
computer to one of the LAN-ports.
4. Boot OpenWRT initramfs image with
> run bootargs_owrt; tftpboot 0x1000000 192.168.1.2:kernel.bin;
bootm 0x1000000;
6. (Optional)
Make a Backup of 'sophos-os1', 'sophos-os2' and 'sophos-data' in case
you ever want to go back to the vendor firmware.
7. Create Ubi Volume on mtd4 by executing
> ubiformat /dev/mtd4 -y
8. Transfer OpenWRT sysupgrade image to the device via SCP and install it
with
> sysupgrade -n <openwrt-image-file>
Back to Stock
=============
If you want to go back to the stock firmware, here is the bootcmd of the
vendor firmware:
> setenv bootargs console=ttyS0,115200 root=/dev/mtdblock5;
nand read 0xc00000 0x00300000 0x100000;
nand read 0x1000000 0x00400000 0x00800000;
bootm 0x1000000 - 0xc00000
Set it via 'setenv' from the U-Boot shell and don't forget to save it
using 'saveenv'!
After this, boot the OpenWRT initramfs image just like you would for
installation. Write back the three vendor partitions using mtd. Reboot
the device afterwards.
