+Subject: [PATCH] include/configs/starfive-vic7100: adjust fdt_addr_r
+
+The default fdt_addr_r of 0x88000000 doesn't work, the kernel never
+boots. Using 0x90000000 works fine.
+
+Since it would overlap with the kernel_comp_addr_r area, this one is
+moved 16 MB further, at 0x91000000.

+BeagleV
+=======
+
+BeagleV is a low-cost RISC-V 64-bit based platform, powered by a
+Starfive JH7100 processor. The current defconfig in Buildroot has been
+tested with the JH7100 chip used on the beta version of the BeagleV
+board.
+
+How to build
+============
+
+$ make beaglev_defconfig
+$ make
+
+Build results
+=============
+
+After building, output/images contains:
+
++ Image
++ fw_payload.bin
++ fw_payload.bin.out
++ fw_payload.elf
++ rootfs.ext2
++ rootfs.ext4
++ sdcard.img
++ u-boot.bin
+
+The two important files are:
+
+ - fw_payload.bin.out, which is the bootloader image, containing
+ both OpenSBI and U-Boot.
+
+ - sdcard.img, the SD card image, which contains the root filesystem,
+ kernel image and Device Tree.
+
+Flashing the SD card image
+==========================
+
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Preparing the board
+===================
+
+Connect the Beagle-V fan to the 5V supply (pin 2 or 4 of the GPIO
+connector) and GND (pin 6 of the GPIO connector).
+
+Connect a TTL UART cable to pin 8 (TX), 10 (RX) and 14 (GND).
+
+Insert your SD card.
+
+Power-up the board using an USB-C cable.
+
+Flashing the bootloader
+=======================
+
+The bootloader pre-flashed on the Beagle-V has a non-working
+fdt_addr_r environment variable value, so it won't work
+as-is. Reflashing the bootloader with the bootloader image produced by
+Buildroot is necessary.
+
+When the board starts up, a pre-loader shows a count down of 2
+seconds, interrupt by pressing any key. You should reach a menu like
+this:
+
+--------8<----------
+
+bootloader version:210209-4547a8d
+ddr 0x00000000, 1M test
+ddr 0x00100000, 2M test
+DDR clk 2133M,Version: 210302-5aea32f
+0
+***************************************************
+*************** FLASH PROGRAMMING *****************
+***************************************************
+
+0:update uboot
+1:quit
+select the function:
+
+--------8<----------
+
+Press 0 and Enter. You will now see "C" characters being
+displayed. Ask your serial port communication program to send
+fw_payload.bin.out using the Xmodem protocol.
+
+After reflashing is complete, restart the board, it will automatically
+start the system from the SD card, and reach the login prompt.
