There are two independent PCIe controllers in MT2712/MT7622 platform,
and each of them should contain an independent MSI domain.
In current architecture, MSI domain will be inherited from the root
bridge, and all of the devices will share the same MSI domain.
Hence that, the PCIe devices will not work properly if the irq number
which required is more than 32.
Split the PCIe node for MT2712/MT7622 platform to fix MSI issue and
comply with the hardware design.

mediatek: rework support for BananaPi BPi-R64 **What's new** * Bring support for the Bananapi BPi-R64 to the level desirable for a nice hackable routerboard. * Use ARM Trusted Firmware A from source. (goodbye binary preloader) * Use Das U-Boot from source. (see previous commit) * Assemble SD-card image using OpenWrt image-commands. (no gen_sd_cruz_foo.sh added, this is not Raspbian) * Updated kernel options to support root filesystem. * Updated DTS to match OpenWrt LAN ports, known LEDs, buttons, ... * Detect root device, handle sysupgrade, config restore, ... * Wire up (known) LEDs and buttons in OpenWrt-fashion. * Build one set of images from SD-card and eMMC. * Hopefully provide a good example of how things can be done right from scratch. **Installation and images** * Have an empty SD-card at hand * Write stuff to the card, as root (card device is /dev/mmcblkX) - write header, gpt, bl2, atf, u-boot and recovery kernel: `cat *bpi-r64-boot-sdcard.img *bpi-r64-initramfs-recovery.fit > /dev/mmcblkX` - rescan partitions: `blockdev --rereadpt /dev/mmcblkX` - write main system to production partition: `cat *bpi-r64-squashfs-sysupgrade.fit > /dev/mmcblkXp5` * Installation to eMMC works using SD-card bootloader via TFTP When running OpenWrt of SD-card, issue this to trigger installation to eMMC: `fw_setenv bootcmd run emmc_init` Be prepared to serve the content of bin/targets/mediatek/mt7622 on TFTP server address 192.168.1.254. **What's missing** * The red LED is always on, probably a hardware bug. * AHCI (probably needs DTS changes) * Ship SD-card image ready with every needed for eMMC install. * The eMMC has a second, currently unused boot partition. This would be ideal to store the WiFi EEPROM and Ethernet MAC address(es). @sinovoip ideas? Thanks to Thomas Hühn @thuehn for providing the hardware!
