  "message": "[flash_ctrl] update `IPoly` parameter in flash scrambler\n\nWhile working on #9322, I noticed the GF(2) irreducible polynomial used\nfor the flash scrambling scheme was not the Conway polynomial with\ndegree 64, but rather the Conway polynomial with degree 32.\n\nAfter discussion in #17443, it was determined that while OK, as the\npolynomial was still irreducible, a better, NIST recommended polynomial\nshould be used instead.\n\nThis updates the GF(2) irreducible polynomial used by the flash\nscrambler to the NIST recommended polynomial for block ciphers:\n`x^64 + x^4 + x^3 + x + 1`.\n\nSigned-off-by: Timothy Trippel \u003cttrippel@google.com\u003e\n",
