| H A D | create_aligned_window.cpp | 8cef63e3 Tue Oct 15 10:23:38 CDT 2019 Alvin Wang <alvinwang@msn.com> Add backend_adjust_offset to avoid the windows overlap
In mihawk, the windows overlap will cause the cache coherence.
Hostboot writes the SPD data to BMC through a window and read it
back with another window. It causes the data missed and DIMM lost.
Hostboot log
23.80714|<<DBG-956|SPD::getMemType() - MemType: 0xff, Error: NoHUID: 0x30008.
BMC log: The overlaped windows
Window @ 0x756e0000 for size 0x00046000 maps flash offset 0x000e7000
Window @ 0x757e0000 for size 0x00048000 maps flash offset 0x000e5000
Tested: 1. In mihawk, it can fix the SPD cache coherence issue
2. Add unit test to verify VPNOR offset alignment
