 Boot Sequence
 -------------
 
-BL2 –> BL31 –> BL33
+The boot process starts from RSE (Runtime Security Engine) that loads the
+Application Processor (AP) BL2 image and signals the System Control Processor (SCP)
+to power up the AP. The AP then runs AP BL2
 
-The boot process starts from RSE (Runtime Security Engine) that loads the BL2 image
-and signals the System Control Processor (SCP) to power up the Application Processor (AP).
-The AP then runs BL2, which loads the rest of the images, including the runtime firmware
-BL31, and proceeds to execute it. Finally, it passes control to the non-secure world
-BL33 (u-boot).
+The primary compute boot flow follows the following steps:
 
-BL2 performs the actions described in the `Trusted Board Boot (TBB)`_ document.
+1. AP BL2:
+
+   * Performs the actions described in the `Trusted Board Boot (TBB)`_ document.
+   * Copies the AP BL31 image from Secure Flash to Secure SRAM
+   * Copies the AP BL32 (OP-TEE) image from Secure Flash to Secure DRAM
+   * Copies the AP BL33 (U-Boot) image from Secure Flash to Normal DRAM
+   * Transfers the execution to AP BL31
+
+2. AP BL31:
+
+   * Initializes Trusted Firmware-A Services
+   * Transfers the execution to AP BL32 and then transfers the execution to AP BL33
+   * During runtime, acts as the Secure Monitor, handling SMC calls,
+     and context switching between secure and non-secure worlds.
+
+3. AP BL32:
+
+   * Initializes OP-TEE environment
+   * Initializes Secure Partitions
+   * Transfers the execution back to AP BL31
+   * During runtime, it facilitates secure communication between the
+     normal world environment (e.g. Linux) and the Trusted Execution Environment.
