cff40ef122 mpc85xx: poll PHY status
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.

7f4b4c29f3 mpc85xx: Drop pci aliases to avoid domain changes
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].

c7528996a5 mpc85xx: change legacy "eeprom" compatible
silences the following message:
> eeprom 0-0051: eeprom driver is deprecated, please use at24 instead

The chip was likely a Dallas Semiconductor and later MAXIM part
before Analog Devices, Inc. bought MAXIM.

From the datasheet:

"The DS28CN01 combines 1024 bits of EEPROM with challenge-and-response
authentication security implemented with the FIPS 180-1/180-2 and
ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1)."

...

"Write Access Requires Knowledge of the Secret
and the Capability of Computing and Transmitting
a 160-Bit MAC as Authorization"

OpenWrt doesn't use it. There's no in-kernel driver
from what I know. Let's document that the chip is
at the location.

583ac0e11d mpc85xx: update lp5521 led-controller node for 5.10
The tricolor LED which is controlled by a lp5521 needed
some maintenance as the driver failed to load in the
current v5.10 image:
| lp5521: probe of 0-0032 failed with error -22

This is because the device-tree needed to be updated
to match the latest led coloring and function trends.

 - removed the device name from the label
 - added color/function properties
 - added required reg and cells properties

For reference a disabled multicolor/RGB is added since this
reflects the real hardware. Unfortunately, the multicolor
sysfs interface isn't supported by yet.

cfe79f2eb8 mpc85xx: Patch HiveAP 330 u-boot to fix boot
When Kernel 5.10 was enabled for mpc85xx, the kernel once again became too
large upon decompression (>7MB or so) to decompress itself on boot (see
FS#4110[1]).

There have been many attempts to fix booting from a compressed kernel on
the HiveAP-330:

- b683f1c36d8a ("mpc85xx: Use gzip compressed kernel on HiveAP-330")
- 98089bb8ba82 ("mpc85xx: Use uncompressed kernel on the HiveAP-330")
- 26cb167a5ca7 ("mpc85xx: Fix Aerohive HiveAP-330 initramfs image")

We can no longer compress the kernel due to size, and the stock bootloader
does not support any other types of compression. Since an uncompressed
kernel no longer fits in the 8MiB kernel partition at 0x2840000, we need to
patch u-boot to autoboot by running variable which isn't set by the
bootloader on each autoboot.

This commit repartitions the HiveAP, requiring a new COMPAT_VERSION,
and uses the DEVICE_COMPAT_MESSAGE to guide the user to patch u-boot,
which changes the variable run on boot to be `owrt_boot`; the user can
then set the value of that variable appropriately.

The following has been documented in the device's OpenWrt wiki page:
<https://openwrt.org/toh/aerohive/hiveap-330>. Please look there
first/too for more information.

The from-stock and upgrade from a previous installation now becomes:

0) setup a network with a dhcp server and a tftp server at serverip
(192.168.1.101) with the initramfs image in the servers root directory.

1) Hook into UART (9600 baud) and enter U-Boot. You may need to enter
a password of administrator or AhNf?d@ta06 if prompted. If the password
doesn't work. Try reseting the device by pressing and holding the reset
button with the stock OS.

2) Once in U-Boot, set the new owrt_boot and tftp+boot the initramfs image:
   Use copy and paste!

 # fw_setenv owrt_boot 'setenv bootargs \"console=ttyS0,$baudrate\";bootm 0xEC040000 - 0xEC000000'
 # save
 # dhcp
 # setenv bootargs console=ttyS0,$baudrate
 # tftpboot 0x1000000 192.168.1.101:openwrt-mpc85xx-p1020-aerohive_hiveap-330-initramfs-kernel.bin
 # bootm

3) Once openwrt booted:
carefully copy and paste this into the root shell. One step at a time

  # 3.0 install kmod-mtd-rw from the internet and load it

  opkg update; opkg install kmod-mtd-rw
  insmod mtd-rw i_want_a_brick=y

  # 3.1 create scripts that modifies uboot

cat <<- "EOF" > /tmp/uboot-update.sh
  . /lib/functions/system.sh
  cp "/dev/mtd$(find_mtd_index 'u-boot')" /tmp/uboot
  cp /tmp/uboot /tmp/uboot_patched
  ofs=$(strings -n80 -td < /tmp/uboot | grep '^ [0-9]* setenv bootargs.*cp\.l' | cut -f2 -d' ')
  for off in $ofs; do
    printf "run owrt_boot;            " | dd of=/tmp/uboot_patched bs=1 seek=${off} conv=notrunc
  done
  md5sum /tmp/uboot*
EOF

  # 3.2 run the script to do the modification

  sh /tmp/uboot-update.sh

  # verify that /tmp/uboot and /tmp/uboot_patched are good
  #
  # my uboot was: (is printed during boot)
  # U-Boot 2009.11 (Jan 12 2017 - 00:27:25), Build: jenkins-HiveOS-Honolulu_AP350_Rel-245
  #
  # d84b45a2e8aca60d630fbd422efc6b39  /tmp/uboot
  # 6dc420f24c2028b9cf7f0c62c0c7f692  /tmp/uboot_patched
  # 98ebc7e7480ce9148cd2799357a844b0  /tmp/uboot-update.sh <-- just for reference

  # 3.3 this produces the /tmp/u-boot_patched file.

  mtd write /tmp/uboot_patched u-boot

3) scp over the sysupgrade file to /tmp/ and run sysupgrade to flash OpenWrt:

  sysupgrade -n /tmp/openwrt-mpc85xx-p1020-aerohive_hiveap-330-squashfs-sysupgrade.bin

4) after the reboot, you are good to go.

Other notes:

- Note that after this sysupgrade, the AP will be unavailable for 7 minutes
  to reformat flash. The tri-color LED does not blink in any way to
  indicate this, though there is no risk in interrupting this process,
  other than the jffs2 reformat being reset.

- Add a uci-default to fix the compat version. This will prevent updates
  from previous versions without going through the installation process.

- Enable CONFIG_MTD_SPLIT_UIMAGE_FW and adjust partitioning to combine
  the kernel and rootfs into a single dts partition to maximize storage
  space, though in practice the kernel can grow no larger than 16MiB due
  to constraints of the older mpc85xx u-boot platform.

- Because of that limit, KERNEL_SIZE has been raised to 16m.

- A .tar.gz of the u-boot source for the AP330 (a.k.a. Goldengate) can
  be found here[2].

- The stock-jffs2 partition is also removed to make more space -- this
  is possible only now that it is no longer split away from the rootfs.

- the console-override is gone. The device will now get the console
  through the bootargs. This has the advantage that you can set a different
  baudrate in uboot and the linux kernel will stick with it!

- due to the repartitioning, the partition layout and names got a makeover.

- the initramfs+fdt method is now combined into a MultiImage initramfs.
  The separate fdt download is no longer needed.

- added uboot-envtools to the mpc85xx target. All targets have uboot and
  this way its available in the initramfs.

d284e6ef0f treewide: convert mtd-mac-address-increment* to generic implementation
Rework patch 681-NET-add-mtd-mac-address-support to implement
only the function to read the mac-address from mtd.
Generalize mtd-mac-address-increment function so it can be applied
to any source of of_get_mac_address.
Rename any mtd-mac-address-increment to mac-address-increment.
Rename any mtd-mac-address-increment-byte to mac-address-increment-byte.

90bfbed7c2 mpc85xx: use generic diag.sh
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.

93bfac468e mpc85xx: update HiveAP-330 dts
initramfs is not the proper name for this, as it stores a boot ramdisk
and not a filesystem. Update the name to reflect it's usage correctly.

If CMDLINE_OVERRIDE is enabled, the chosen bootargs aren't used at all.
Drop them from the device tree source file to not cause confusion.

Remove the noinitrd bootarg. Due to the empty ramdisk this parameter
isn't required any longer:

  [    0.000000] Initrd not found or empty - disabling initrd
