-- add clear trusty memory flag
In some cases such as UOS power off or UOS full reset,
need to clear trusty memory,no need to clear memory such as
UOS S3 or UOS system reset,then add a flag to distinguish it
when destroy secure world.
-- Restore trusty memory to guest normal world.
-- Moved free trusty EPT inside destroy_secure_world
In some cases such as UOS S3 or UOS system reset,
only need to free trusty EPT, this patch move free
trusty EPT inside destroy_secure_world.
Because PD/PT are shared in both secure world's EPT
and normal world's EPT,before freeing trusty EPT,
it will memset all PDPTEs except trusty memory,
then call 'free_ept_mem', it can only free trusty EPT,
and does't affect shared normal world EPT.
v2-->v3:
-- Used new mmu api ept_mr_add when restore trusty memory
to SOS and normal world
-- Dropped this patch "Removed reverted page tables for trusty memory"
because map_mem will be removed in future
It will have a patch, need to update this api(ept_mr_add),
it will not create inverted page tables for trusty memory.
v1-->v2:
-- free trusty ept
still use free_ept_mem, not add a new api,but need to
memset pdptes except trusty memory
-- Removed reverted page tables for trusty memory.
