from armv8 spec, no matter TCR_EL1/2/3, there are
1. SH (shareability)
2. ORGN (outer cacheability)
3. IRGN(inner cacheability)
but in the each level block/page descriptor, there are also
sharability, inner, outter, cacheability as well.
What is the difference between the sharability, inner/outer
cacheability between TCR and Block/page descriptors?
Why are there attributes setting keep in TCR?
appreciate your kind help in advance,
