7553580b64 thermosphere: major refactor of memory map 
- use recursive stage 1 page table (thanks @fincs for this idea)
- NULL now unmapped
- no identity mapping
- image + GICv2 now mapped at the same address for every platform
- tempbss mapped just after "real" bss, can now steal unused mem from
the latter
- no hardcoded VAs for other MMIO devices
- tegra: remove timers, use the generic timer instead

2753b6cf8f thermosphere: trap set/way dcache access 
note: qemu does not implement the trap
 2020-02-04 19:12:21 +00:00
TuxSH
114cdc5aa4 thermosphere: use barriers and caches *properly*. Cache code refactoring 
- set/way cache ops create losses of coherency, do not broadcast and are only meant to be used on boot, period.

Cache ops by VA are **the only way** to do data cache maintenance.

Fix a bug where the L2 cache was evicted by each core. It shouldn't have.

- Cleaning dcache to PoU and invalidating icache to PoU, by VA is sufficient for self-modifying code

- Since we operate within a single cluster and don't do DMA, we almost always operate within the inner shareability domain

(commit untested on real hw)
