"about": "One description of Alif Semiconductor's Ensemble SoC memory map, shared by the twins of both of its sides: the Cortex-M55 real-time subsystems (RTSS-HP, RTSS-HE) and the Cortex-A32 application subsystem (APSS) that runs Linux. Addresses are facts read from Alif's published device trees and Yocto machine files (sources below); no text of them is copied. The peripheral list is the APSS (Linux) view of the global map, which the M55s share; each M55 also has its own tightly coupled memories at the same local addresses (rtss below).",
