![]() spi-nor.c issues 4B commands for some Flash chips bigger than 16Mbytes. Xeon(R) D-1500 documentation mentions its Integrated PCH Logic supports Flash chips up to 64Mbytes. D-1500 Integrated PCH documenation however has inconsistencies regarding FADDR register width and says nothing about particular commands issued to support 64Mbytes of Flash. Nevetheless the tests on Xeon(R) CPU D-1548 with 512Mbit Flash chips Macronix MX25L51245G and Micron MT25QL512A showed that erase, write and read operations work just fine after SPINOR_OP_READ_4B and SPINOR_OP_READ_FAST_4B are white-listed (currently only SPINOR_OP_READ_FAST_4B is used and only for Macronix).
