The Buffalo Linkstation LS421DE comes with a Ricoh RS5C372A real time
clock. This RTC has the INTRA pin connected to the power management
circuit, allowing to wake up the device from the power off state when an
alarm is scheduled.
Add the "wakeup-source" property in the RTC dts node to allow the use
of the alarm.
Example of use, the device is powered off and it comes to life after 5
minutes:
echo $(expr $(date '+%s') + 60 * 5) > /sys/class/rtc/rtc0/wakealarm
poweroff
This feature isn't available in the stock firmware.

The Buffalo Linkstation LS421DE isn't able to enable the Level 2 cache
(AKA Aurora cache). As of result of this, the throughput is about half of
the expected, e.g when doing network data transfers.
Fix it by adding the broken-idle property in the coherency fabric node.

This patch adds support for Globalscale ESPRESSObin-Ultra. Device uses
the same Armada-3720 SoC with extended hardware support.
- SoC: Armada-3720
- RAM: 1 GB DDR4
- Flash: 4MB SPI NOR (mx25u3235f) + 8 GB eMMC
- Ethernet: Topaz 6341 88e6341 (4x GB LAN + 1x WAN with 30W PoE)
- WiFI: 2x2 802.11ac Wi-Fi marvell (88w8997 PCIe+USB)
- 1x USB 2.0 port
- 1x USB 3.0 port
- 1x microSD slot
- 1x mini-PCIe slot (USB [with nano-sim slot])
- 1x mini-USB debug UART
- 1x RTC Clock and battery
- 1x reset button
- 1x power button
- 4x LED (RGBY)
- Optional 1x M.2 2280 slot
** Installation **
Copy dtb from build_dir to bin/ and run tftpserver there:
$ cp ./build_dir/target-aarch64_cortex-a53_musl/linux-mvebu_cortexa53/
linux-5.4.65/arch/arm64/boot/dts/marvell/armada-3720-espressobin-ultra.dtb
bin/targets/mvebu/cortexa53/
$ in.tftpd -L -s bin/targets/mvebu/cortexa53/
Connect to the device UART via microUSB port on the back side and power on the device.
Power on the device and hit any key to stop the autoboot.
Set serverip (host IP) and ipaddr (any free IP address on the same subnet), e.g:
$ setenv serverip 192.168.1.10 # Host
$ setenv ipaddr 192.168.1.15 # Device
Ping server to confirm network is working:
$ ping $serverip
Using neta@30000 device
host 192.168.1.15 is alive
Tftpboot the firmware:
$ tftpboot $kernel_addr_r openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-initramfs-kernel.bin
$ tftpboot $fdt_addr_r armada-3720-espressobin-ultra.dtb
Set the console and boot the image:
$ setenv bootargs $console
$ booti $kernel_addr_r - $fdt_addr_r
Once the initramfs is booted, transfer openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img.gz
to /tmp dir on the device.
Gunzip and dd the image:
$ gunzip /tmp/openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img.gz
$ dd if=/tmp/openwrt-mvebu-cortexa53-globalscale_espressobin-ultra-squashfs-sdcard.img of=/dev/mmcblk0 && sync
Reboot the device.
