CfiMemory: This is modelling a flash memory adhering to the Common Flash Interface (CFI): JEDEC JESD68.01 JEDEC JEP137B Intel Application Note 646 This is as of now a pure functional model of a flash controller: no timing/power information has been encoded in it and it is therefore not representive of a real device. Some voltage/timing values have nevertheless been encoded in the CFI table. This is just a requirement from the CFI specification: guest software might query those entries, but they are not reflected in gem5 statistics. The model is meant to be used to allow execution of flash drivers (e.g. UEFI firmware storing EFI variables in non volatile memory) JIRA: https://gem5.atlassian.net/browse/GEM5-913 Change-Id: Id99e331ac8237f3ecb69d618da0d7ca7b038cd1f Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/41495 Reviewed-by: Jason Lowe-Power <power.jg@gmail.com> Maintainer: Jason Lowe-Power <power.jg@gmail.com> Tested-by: kokoro <noreply+kokoro@google.com>
