to look at the new patch set (#3).
Change subject: sim: Implement load_addr_mask auto-calculation
......................................................................
sim: Implement load_addr_mask auto-calculation
Recent Linux kernels for AArch64 have changed their start addresses
but we still want to relocate the kernel to 0x80080000 which
required hacking the load_addr_mask in Realview.py to be 0x7ffffff
from 0xfffffff to mask off the proper number of MSBs to load the
kernel in the desired location. To avoid having to make this change
in the future again, we auto-calculate the load_addr_mask if it is
specified as 0x0 in the System sim-object to find the most restrictive
address mask instead of having the configuration specify it. If the
configuration does specify the address mask, we use it instead of
auto-calculating.
