define Package/apboot-aruba-ipq806x/description
  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.
