This is unfortunately needed to disable the signature verification
in the stock bootloader.

+  Patched build of the Aruba APBoot bootloader (a vendor fork of U-Boot) for
+  the Aruba AP-324 / AP-325 access points (board "octomore"). The factory
+  bootloader enforces RSA signatures on the firmware; this build removes the
+  signature check and switches the console to 115200 baud so that OpenWrt can
+  be booted. The resulting "u-boot.mbn" is meant to be flashed to the APPSBL
+  SPI-flash partition via the serial console.

+
+# APBoot is a freestanding U-Boot, so build it with OpenWrt's target
+# cross-toolchain instead of the bare-metal arm-none-eabi- default. The legacy
+# Makefile honours an externally supplied CROSS_COMPILE.
