[Buildroot] [PATCH v2 2/2] configs/beaglev_ahead: new defconfig

From: Kilian Zinnecker <kilian.zinnecker at mail.de>
This patch adds board support for the BeagleV-Ahead. It uses a
custom kernel for the board's SoC. As the SoC has an outdated and
currently not supported version of the RISC-V vector extension, the
vector extension is disabled.

+Subject: [PATCH] Overwrite bootcmd by force
+
+This patch is a dirty hack: Trying to overwrite the bootcmd via the
+usual BOOT_COMMAND had no effect: Upon boot the bootcmd defaulted
+to some preset value and could not be changed easily. Therefore a
+hook is used to force the bootcmd to be overwritten.

+
+Creating bootable SD card:
+==========================
+
+Simply invoke (as root)
+
+sudo dd if=output/images/sdcard.img of=/dev/sdX && sync
+
+Where X is your SD card device.
+
+Booting:
+========
+
+SD card boot button:
+--------------------
+To let the board boot from SD card, keep the "SD button" pressed during power
+up / power cycle. The button is near the SD card slot.
+
+Serial console:
+---------------
+The BeagleV-Ahead has a "Debug" GPIO header. Its layout can be seen here:
+https://docs.beagleboard.org/latest/boards/beaglev/ahead/02-quick-start.html#access-uart-debug-console
+
+Note, that there are reported issues with some uart interface cables/dongles:
+https://forum.beagleboard.org/t/beaglev-ahead-debug-terminal-problems/35331
+
+Baudrate for this board is 115200.
+
+Login:
+------
+Enter 'root' as login user, and the prompt is ready.
