102009f3ea mpc85xx: p1020: convert Aerohive AP330/AP350 to simpleImage
with 6.1, the kernel no longer fitted into the 16 MiB and
kicking down the can and increasing KERNEL_SIZE to 20 MiB
didn't help as the device failed to boot.

Using 'kernel-bin | gzip | uimage gzip' didn't work since the
uboot does not have enough heap to decompress these big kernels.

And finally playing around with uboot was more a hassle than
converting this device to take the simpleImage-boot-route in
the future.

Note: The device now takes even longer on the first boot-up after
the flash due to JFFS2 initializing all the remaining flash.
Be prepared to wait up to 10 minutes before the green status LED
stops blinking and will shine a solid green!

(On the plus site: the device now has ~10 MiB of additional
space for rootfs+rootfs_data).

Note2: This patch includes a kernel patch refresh.

6a8b831593 mpc85xx: p1010: change wrapper address of simple image devices
Kernel and initramfs size grows. Now uncompressed initramfs image and
regular kernel image overlaps configured area:

57d7382cb1 mpc85xx: increase available RAM on Extreme Networks WS-AP3825i
The system-mamory size was page-aligned prior to this commit, only
enabling to use 192MB of system memory of the 256 available.

This was due to the system-memory being manually shrinked to reserve the
upper 1MB for the second-core bootpage in the loader as well as the OS.

Fix this properly in the loader and in Linux using reserved-memory
definitions. This enables the device to use 250MB of system memory.

95d5a99537 mpc85xx: add support for Aerohive BR200-WP
The following adds the Aerohive BR200-WP router to OpenWrt under
the mpc85xx/p1010 subtarget.

Hardware:
- SoC: Freescale P1011
- NOR: Intel JS28F512M29EWH 64MB
- Memory: 2x Nanya NT5TU64M16GG-AC 128MB (Total of 256MB)
- 2.4GHz WiFi: Atheros AR9390-AL1A
- Eth1: Atheros AR8035-A PoE
- 2x LEDs
- 1x Button
- PoE PSE

Flashing:
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.
2. Once in U-Boot, tftp boot the initramfs image:
   dhcp; setenv serverip 192.168.1.3;
   tftpboot 0x2004000 openwrt-mpc85xx-p1010-aerohive_br200-wp-initramfs-kernel.bin;
   bootm 0x2004000;
3. Once booted, scp over the sysupgrade file and sysupgrade the device
to flash LEDE to the NOR.

Note:

MAC assigns are taken from stock firmware:

FLASH: 32M NOR (Spansion S25FL256S)

ETH:   2x Gigabit Ethernet (Atheros AR8033 / AR8035)
UART:  115200 8N1 (RJ-45 Cisco)

Installation
------------
1. Grab the OpenWrt initramfs, rename it to ap3715.bin. Place it in
   the root directory of a TFTP server and serve it at
   192.168.1.66/24.

2. Connect to the serial port and boot the AP. Stop autoboot in U-Boot
   by pressing Enter when prompted. Credentials are identical to the one
   in the APs interface. By default it is admin / new2day.

3. Alter the bootcmd in U-Boot:

 $ setenv ramboot_openwrt "setenv ipaddr 192.168.1.1;
   setenv serverip 192.168.1.66; tftpboot 0x2000000 ap3715.bin; bootm"

 $ setenv boot_openwrt "sf probe 0; sf read 0x2000000 0x140000 0x1000000;
   bootm 0x2000000"

 $ setenv bootcmd "run boot_openwrt"

 $ saveenv

4. Boot the initramfs image

 $ run ramboot_openwrt

5. Transfer the OpenWrt sysupgrade image to the AP using SCP. Install
   using sysupgrade.

 $ sysupgrade -n <path-to-sysupgrade.bin>

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.

The wrapper images actually do not represent a target. They are built
based on the kernel configuration. Only copy the resulting images to

Hardware

FLASH:  1 MB SPI-NOR
        512 MB NAND
ETH:    3x Gigabite Ethernet (Atheros AR8033)
SERIAL: Cisco RJ-45 (115200 8N1)
RTC:    Battery-Backed RTC (I2C)

Installation
------------

1. Patch U-Boot by dumping the content of the SPI-Flash using a SPI
   programmer. The SHA1 hash for the U-Boot password is currently
   unknown.

   A tool for patching U-Boot is available at
   https://github.com/blocktrron/t10-uboot-patcher/

   You can also patch the unknown password yourself. The SHA1 hash is
   E597301A1D89FF3F6D318DBF4DBA0A5ABC5ECBEA

2. Interrupt the bootmenu by pressing CTRL+C. A password prompt appears.
   The patched password is '1234' (without quotation marks)

3. Download the OpenWrt initramfs image. Copy it to a TFTP server
   reachable at 10.0.1.13/24 and rename it to uImage.

4. Connect the TFTP server to ethernet port 0 of the Watchguard T10.

5. Download and boot the initramfs image by entering "tftpboot; bootm;"
   in U-Boot.

6. After OpenWrt booted, create a UBI volume on the old data partition.
   The "ubi" mtd partition should be mtd7, check this using

   $ cat /proc/mtd

   Create a UBI partition by executing

   $ ubiformat /dev/mtd7 -y

7. Increase the loadable kernel-size of U-Boot by executing

   $ fw_setenv SysAKernSize 800000

8. Transfer the OpenWrt sysupgrade image to the Watchguard T10 using
   scp. Install the image by using sysupgrade:

   $ sysupgrade -n <path-to-sysupgrade>

   Note: The LAN ports of the T10 are 1 & 2 while 0 is WAN. You might
   have to change the ethernet-port.

9. OpenWrt should now boot from the internal NAND. Enjoy.

218f425b61 kernel: Add CONFIG_PPC_QUEUED_SPINLOCKS configuration option
The CONFIG_PPC_QUEUED_SPINLOCKS configuration option is not defined for
kernel 5.15, it is defined for kernel 5.10.

This fixes the compilation of mpc85xx/p2020 with kernel 5.15.

mcp85xx: Switch TP-Link TL-WDR4900 v1 to DSA
This patch introduces DSA support for TP-Link TL-WDR4900 v1 switch.
Swconfig driver for QCA8327 switch is removed because this router is
only one device which use Qualcom swconfig switch.

mpc85xx: p2020: kernel: enable CONFIG_BLK_DEV_NVME
Enables use of NVMe storage devices with appropriate adapter in miniPCIe slots (including for boot)
in Turris 1.x routers and possibly NXP P2020RDB boards
(these are the only currently supported p2020 devices according to docs[^1]).

Proper detection, mountability and readability was proved to be working
on Turris 1.1, OpenWrt 21.02 with similar configuration.

Increases gzip compressed kernel size by approximately 37 KiB (from 3 703 KiB to 3 740 KiB).

Should boot from those devices be possible the driver needs to be built in.
Inclusion as a module would prevent this functionality.

CONFIG_BLK_DEV_NVME=y
Includes NVMe driver in the kernel.[^2]

CONFIG_NVME_CORE=y
Selected by CONFIG_BLK_DEV_NVME.[^3] Not necessarily needed to be enabled explicitly,
but included to match the form of similar functionality implementations
for mvebu, x86_64 and rockchip_armv8 targets.

CONFIG_NVME_MULTIPATH disabled explicitly to prevent using more space than necessary.
