b1cfbff0a7 mvebu: uDPU: switch default kernel and U-Boot PHY mode
Certain SFP modules (most notably Nokia GPON ones) first check
connectivity on 1000base-x, and switch to 2500base-x afterwards. This
is considered a quirk so the phylink switches the interface to
2500base-x as well.

However, after power-cycling the uDPU device, network interface/SFP module
will not work correctly until the module is re-seated. This patch
resolves this issue by forcing the interface to be brought up in
2500base-x mode by default.

3fdb08681b mvebu: tidy up support for GL.iNet GL-MV1000
This fixes a bunch of cosmetic issues with GL.iNet GL-MV1000:

- apply alphabetic sorting in multiple files
- use armada-3720 prefix for DTS like for other devices
- fix vendor capitalization for model in DTSes
- remove trivial comment in DTS files
- use DEVICE_VENDOR/DEVICE_MODEL
- remove redundant SUPPORTED_DEVICES
- use SOC instead of DEVICE_DTS
- remove empty line at EOF

85ef69b202 mvebu: add support for Buffalo LinkStation LS421DE
Buffalo LinkStation LS421DE is a dual bay NAS, based on Marvell Armada 370

Hardware:
   SoC:         Marvell Armada 88F6707-A1
   CPU:         Cortex-A9 1200 MHz, 1 core
   Flash:       SPI-NOR 1 MiB, NAND 512 MiB
   RAM:         DDR3 512 MiB
   Ethernet:    1x 10/100/1000 Mbps
   USB:         1x 2.0, 1x 3.0
   SATA:        2x 3.0 Gbps
   LEDs/Input : 5x / 2x (1x button, 1x slide-switch)
   RTC:         Ricoh RS5C372A, I2C, no battery

Flash instruction (UART+TFTP):
  1. Downgrade the OEM firmware to 1.34 version (BUFFALO_BOOTVER=0.13)
  2. Remove any hard drive from inside the bays.
  3. Boot the Openwrt initramfs image using the U-Boot serial console:
         tftpboot 0x1200000 buffalo_ls421de-initramfs-kernel.bin
         bootm 0x1200000
  4. Flash the sysupgrade image using the Openwrt console:
         sysupgrade -n buffalo_ls421de-squashfs-sysupgrade.bin
  5. Wait until it finish, the device will reboot with Openwrt installed
     on the NAND flash.

Note:
  - Device shuting down doesn't work, even if the power slide switch is
    used. We must first, via MDIO, set the unused LED2 at the ethernet
    phy0 to off state. Reboot works ok.

2d61f8821c mvebu: cortexa9: correct cpu subtype
Armada 370  processors have only 16 double-precision registers. The
change introduced by 8dcc108760 ("toolchain: ARM: Fix toolchain
compilation for gcc 8.x") switched accidentally the toolchain for mvebu
cortexa9 subtarget to cpu type with 32 double-precision registers. This
stems from gcc defaults which assume "vfpv3-d32" if only "vfpv3" as mfpu
is specified. That change resulted in unusable image, in which kernel
will kill userspace as soon as it causing "Illegal instruction".

ace1bfb554 mvebu: Refresh kernel 4.19 configuration

When did a compile with the default settings I had to select some
kernel configuration options.
