ipq806x: add support for Buffalo WXR-2533DHP
Buffalo WXR-2533DHP is a 2.4/5 GHz band 11ac router, based on Qualcomm IPQ8064. The U-Boot on WXR-2533DHP employs a complicated dual firmware protection scheme against corruptions of the kernel and rootfs images. See the notes in buffalo.sh for details. specifications: - Qualcomm IPQ8064 (384 - 1,400 MHz, 2C2T) - 512 MB of RAM (DDR3) - 256 MB of Flash (NAND) - 4T4R 2.4/5 GHz Wlan (QCA9980) - 5x 10/100/1000 Mbps Ethernet - 10x LEDs, 8x keys (6x buttons, 2x slide-switches) - 2x USB 3.0 Type-A - 12VDC/4A AC Adapter - UART through-hole on PCB - J3: Vcc, GND, TX, RX from USB port side - 115200n8 Boot instructions for the initramfs image: 1. Prepare the TFTP server with the initramfs image renamed to "wxr2300dhp-initramfs.uImage" and IP address "192.168.11.10". 2. Press the "AOSS" button while powering on the WXR-2533DHP. 3. Wait until the "Wireless" LED flashes before releasing the AOSS button. The WXR-2533DHP will grab the image from TFTP server and will boot it. Flashing instructions: To persistently write the firmware, flash an openwrt sysupgrade image from inside the initramfs, for example transfer via `scp <sysupgrade> root@192.168.1.1:/tmp` and flash on the device with `sysupgrade -n /tmp/<sysupgrade>`. Then wait ~120 seconds to let it finish the flashing process. Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com> Signed-off-by: Christian Lamparter <chunkeey@gmail.com> [reworded message]

+# The mtd partition 'ubi' and 'rootfs_1' on NAND flash are os-image
+# partitions. These partitions are called as "Bank1/Bank2" in U-Boot
+# on WXR-2533DHP, and they are checked conditions when booting.
+# Then, U-Boot checks kernel and rootfs volumes in ubi, but U-Boot
+# needs "ubi_rootfs" as rootfs volume name. And, U-Boot checks the
+# checksum at the end of rootfs (ubi_rootfs).
+# When U-Boot writes os-image into the Bank, only kernel, rootfs
+# (ubi_rootfs) and rootfs_data (ubi_rootfs_data) volumes are wrote
+# into the Bank. (not full ubi image)
+#
+# == U-Boot Behaviors ==
+# - Bank1/Bank2 images are good, images are different
+# -> writes os-image to Bank1 from Bank2
+# (this behavior is used to firmware upgrade in stock firmware)
+# - Bank1 image is broken (or checksum error)
+# -> writes os-image to Bank1 from Bank2
+# - Bank2 image is broken (or checksum error)
+# -> writes os-image to Bank2 from Bank1
+# - Bank1/Bank2 images are broken (or checksum error)
