~~<check back later~~ for ~~diff>~~

+

* TPIDR_EL1 is now set to 0, and VBAR_EL1 is now set to a table that infinite loops on all exceptions other than synchronous from same exception level.

+

** synch_spx_el1 now restores a number of registers from a context with pointer in TPIDR_EL1, and then clears TPIDR_EL1.

+

* TPIDR_EL1 is now set to a context save struct before manufacturer-specific system registers are set.

+

** Support was added for Cortex-A53 specific CPU initialization.

+

* Kernel .rodata is now initially mapped as RW- instead of R--, and then reprotected to RW- after relocations are completed.

+

** This allows for/implements .rel.ro.
