 +====== Trusted Firmware-A (ARM Trusted Firmware) ======

 +The ARM Trusted Firmware is embedded within the supplied U-Boot loader, and aren't used by the end-user directly. 
 +However, some platforms require the Trusted Firmware to boot a Kernel. 
 + 
 +The single build script is used to produce the trusted firmware assets for all supported Hardware Models.

 +==== Kernel Package Build Helpers ====
 +
 +The Pinebook Pro (RK3399 SoC) requires a firmware blob to be installed within the OS InitRD (see further down) in order to light up one of the display ports.
 +To facilitate this, a helper script is executed from the kernel.SlackBuild script when the OS InitRD is constructed.  This helper extracts the relevant firmware blob from the Slackware a/kernel-firmware package.
