1=============================== 2Recent development (unreleased) 3=============================== 4 5This document describes the major changes that are expected to be included in 6the next release of flashrom and which are currently only available by source 7code checkout (see :doc:`../dev_guide/building_from_source`). These changes 8may be further revised before the next release. 9 10Known issues 11============ 12 13AMD-based PCs with FCH are unable to read flash contents for internal (BIOS 14flash) chips larger than 16 MB, and attempting to do so may crash the system. 15Systems with AMD "Promontory" IO extenders (mostly "Zen" desktop platforms) are 16not currently supported. 17 18https://ticket.coreboot.org/issues/370 19 20Build only supported with Meson 21=============================== 22 23As documented in the :doc:`v1.4 release notes <v_1_4>`, support for building 24flashrom with make has been removed; all Makefiles have been deleted. Meson is 25now the only supported tool for building flashrom from source. 26 27New Feature 28=========== 29 30Libpci 3.13.0 and onwards support ECAM to access pci registers. Flashrom will 31be moved to ECAM from IO port 0xcf8/0xcfc if the libpci version is >= 3.13.0. 32The ECAM has been supported for a very long time, most platforms should support 33it. For those platforms don't support ECAM, libpci will terminate the process by 34exit. 35 36Chipset support 37=============== 38 39Added Raptor Point PCH support. 40 41Chip model support added 42======================== 43 44* FM25Q04 45* FM25Q64 46* FM25Q128 47 48* GD25B128E 49* GD25B256E 50* GD25B512MF 51* GD25F64F 52* GD25F256F 53* GD25R128E 54* GD25R256E 55* GD25R512MF 56* GD25LB256F 57* GD25LB512ME 58* GD25LB512MF 59* GD25LR256F 60* GD25LR512MF 61* GD25LF256F 62* GD25LF512MF 63 64* MX25U25645G 65* MX77U51250F 66 67* W25Q32JV_M 68 69* XM25LU64C 70* XM25QH32C 71* XM25QH32D 72* XM25QH64D 73* XM25QH128D 74* XM25QH256D 75* XM25QH512C 76* XM25QH512D 77* XM25QU16C 78* XM25QU32C 79* XM25QU128D 80* XM25QU256D 81* XM25QU512C 82* XM25QU512D 83
