qualcommax: ipq50xx: Add support for Linksys MR5500

Add support for Linksys MR5500 (Hydra 6 Pro).

Speficiations:
* SoC: Qualcomm IPQ5018 (64-bit dual-core ARM Cortex-A53 @ 1.0Ghz)
* Memory: Kingston D2516ECMDXGJD (512 MiB)
* Serial Port: 3v3 TTL 115200n8
* Wi-Fi: IPQ5018 (2x2 2.4 Ghz 802.11b/g/n/ax)
         QCN9024 (4x4:4 5 Ghz 802.11an/ac/ax)
* Ethernet: IPQ5018 integrated virtual switch connected to an external
            QCA8337 switch (4 Ports 10/100/1000 GBASE-T)
* Flash: Gigadevice GD5F2GQ5REYIH (256 MiB)
* LEDs: 1x multi-color PWM LED
        1x blue led for USB (GPIO 19 Active High)
* Buttons: 1x WPS (GPIO 27 Active Low)
           1x Reset (GPIO 28 Acive Low)
           5x ethernet port LEDs (amber for activity & green for link up)
* Peripherals: 1x USB2 (powered by GPIO 17 Active Low)
               support for USB3 will be added in a separate PR
* FCC ID: 2AYRA-03734

Flash instructions:
1. On OEM firmware, login to the device (typically at http://192.168.1.1) and click 'CA'
in the bottom right corner -> Connectivity -> Manual Upgrade. Alternatively, browse to
http://<router IP>/fwupdate.html.
Upgrade firmware using openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin image.
Optionally install on second partition, after first boot check actual partition:
fw_printenv -n boot_part
and install firmware on second partition using command in case of 2:
mtd -r -e kernel -n write openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin kernel
and in case of 1:
mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin alt_kernel
2. Installation using serial connection from OEM firmware (default login: root, password: admin):
fw_printenv -n boot_part
In case of 2:
flash_erase /dev/mtd12 0 0
nandwrite -p /dev/mtd12 openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin
or in case of 1:
flash_erase /dev/mtd14 0 0
nandwrite -p /dev/mtd14 openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin
After first boot install firmware on second partition:
mtd -r -e kernel -n write openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin kernel
or:
mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq50xx-linksys_mr5500-squashfs-factory.bin alt_kernel
3. Back to the OEM firmware.
Download firmware from OEM website:
MR5500: https://support.linksys.com/kb/article/207-en/
From serial or SSH:
fw_printenv boot_part
in case of 1:
mtd -r -e alt_kernel -n write FW_MR5500_1.1.2.209598_prod.img alt_kernel
else in case of 2:
mtd -r -e kernel -n write FW_MR5500_1.1.2.209598_prod.img kernel
4. Boot from USB
This allows you loading an OpenWrt image into RAM and is meant for recovery scenarios only.
Enable loading image from USB in u-boot. From serial or SSH:
fw_setenv bootusb 'usb start && usbboot &loadaddr && bootm $loadaddr'
fw_setenv bootcmd 'run bootusb; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'
Copy OpenWrt initramfs image to USB:
dd bs=1M if=openwrt-qualcommax-ipq50xx-linksys_mr5500-initramfs-uImage.itb of=/dev/sda
