As a firmware developer, I want vemu to finish its Cortex-A53 quad-core (BCM2837) model, so that I can depend on pi 3 family / Zero 2 W (the easiest 64-bit Pi target) for production firmware, not just the common path.

Why it matters

Pi 3 family / Zero 2 W (the easiest 64-bit Pi target)

Summary

4x Cortex-A53 with SMP bring-up, WFE/SEV, SGIs/IPIs

Scope of work

Partially modeled. Complete the missing mechanics of Cortex-A53 quad-core (BCM2837). What it is: 4x Cortex-A53 with SMP bring-up, WFE/SEV, SGIs/IPIs. Why it matters: Pi 3 family / Zero 2 W (the easiest 64-bit Pi target).

Current state

Status: Partially implemented. Notes / evidence: A53 single-core modeled (vemu-cortex-a); quad/SMP bring-up is stubbed.

Blocked by 4

Fund these first - this work can't be completed until they ship.

Funding this also clears the way for the work below.
