DISTRO lmp-base for easy Kernel Image access

The default distro used by a FoundriesFactory is lmp, designed to provide a secure and updatable environment needed during the operation of an end product. However this distro configuration is not ideal during the porting process. Therefore we also support another distro configuration: lmp-base, which provides an easier development environment as it has a boot directory which includes the Linux Kernel image and the DTB file, and a read-writable rootfs. See detailed information on how lmp and lmp-base differ LmP Distros.

In the following sections, the focus is on the boot flow (1) show on Fig. 103. This boot flow is common on the i.MX8 and i.MX8M SoC families. It is also common for i.MX6 and i.MX7 SoC families, however TF-A is not supported for these SoC families and is excluded from the boot flow.
