This commit modifies mtd partitions define for Buffalo BHR-4GRV2 and move it to generic subtarget. In Buffalo BHR-4GRV2, "kernel" partition is located behined "rootfs" partition in the stock firmware. This causes the size of the kernel to be limited by the fixed value. 0x50000 0xe80000 0xff0000 +-------------------------------+--------------+ | rootfs | kernel | | (14528k) | (1472k) | +-------------------------------+--------------+ After ar71xx was updated to Kernel 4.14, the kernel size of BHR-4GRV2 exceeded the limit, and it breaks builds on official buildbot. Since this issue was also confirmed in ath79, I modified the mtd partitions to get rid of that limitation. 0x50000 0xff0000 +----------------------------------------------+ | firmware | | (16000k) | +----------------------------------------------+ However, this commit breaks compatibility with ar71xx firmware, so I dropped "SUPPORTED_DEVICES += bhr-4grv2". This commit requires new flash instruction instead of the old one. Flash instruction using initramfs image: 1. Connect the computer to the LAN port of BHR-4GRV2 2. Set the IP address of the computer to 192.168.12.10 3. Rename the OpenWrt initramfs image to "bhr4grv2-uImage-initramfs-gzip.bin" and place it into the TFTP directory 4. Start the tftp server on the computer 5. While holding down the "ECO" button, connect power cable to BHR-4GRV2 and turn on it 6. Flashing (orange) diag LED and release the finger from the button, BHR-4GRV2 downloads the intiramfs image from TFTP server and boot with it 7. On the initramfs image, create "/etc/fw_env.config" file with following contents /dev/mtd1 0x0 0x10000 0x10000 8. Execute following commands to add environment variables for u-boot fw_setenv ipaddr 192.168.12.1 fw_setenv serverip 192.168.12.10 fw_setenv ethaddr 00:aa:bb:cc:dd:ee fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000" 9. Perform sysupgrade with squashfs-sysupgrade image 10. Wait ~150 seconds to complete flashing And this commit includes small fix; BHR-4GRV2 has QCA9557 as a SoC, not QCA9558.
