Tested by flashing and reading an internal Winbond ROM on NetBSD-current.
# flashrom/1.0.1
6b9e934f linux_spi: Reduce maximum read chunksize
Improves compatibility with older Linux kernels that interpreted the interface differently.
30c4cecd Makefile: Disable `-Werror=deprecated-declarations` on release branch
Just to be able to compile the 1.0.x branch on newer systems.
5639af64 linux_spi: Hardcode default spispeed of 2MHz
Default speed of kernel drivers isn't always sane (any more).
993e162d dediprog: Fix small, unaligned reads
An actual bug, discovered during experiments with arbitrary layouts.
ec8b8a7f board_enable.c: Fix dmi_match string for ThinkPad X201
Probably just wasn't tested before.
69f96f60 Fix verification with sparse layouts
A regression that sneaked into flashrom-1.0: When verifying the whole flash after a partial write with a sparse layout (i.e. a layout whose regions don't cover the whole chip), flashrom tried to verify against the wrong data and failed.
a3db7ed5 Fix erasing of unaligned regions
This never worked correctly from the beginning. We completely erased every block that touched an included layout region. Now, we restore surrounding data in case a block expands beyond the region.
# flashrom/1.0
New major user-visible features
Support layouts for read and erase commands
New command line switch --noverify-all (-N) allows flashing of individual regions without reading the whole flash chip (particular useful with locked down Intel ME firmware)
New command line switch --ifd to read the layout from an Intel Firmware Descriptor on flash
We got rid of the delay-loop calibration (if the OS provides an accurate timer through clock_gettime())
Reading speed of USB programmers should have increased (reading bigger chunks at once, we reduce the overhead)
Support Intel 100 series PCHs (Sunrise Point, coupled with Skylake and Kaby Lake) and C620 series PCHs (Lewisburg paired with Workstation/Server versions of the former)
New programmers
Intel 100 series / C620 series PCHs
Intel I210 NICs (EEPROM and SPI)
AMD Merlin Falcon (FP4)
New chips
W25Q128.W
# flashrom/0.9.9
New major user-visible features
Allow to link flashrom statically (with make CONFIG_STATIC=yes)
Ease debugging of build problems with libraries
Output way more debug information to build_details.txt
Provide list of set make configuration variables that make builds fail
Allow to easily disable groups of programmers depending on a library (make CONFIG_ENABLE_LIBUSB0_PROGRAMMERS=no CONFIG_ENABLE_LIBUSB1_PROGRAMMERS=no CONFIG_ENABLE_LIBPCI_PROGRAMMERS=no)
Ignore 0x00 as a flash chip manufacturer ID in the generic match to avoid ambiguous messages
Various improvements for serprog-based programmers
Support arbitrary UART baud rates on Windows
New programmers
Enable the dediprog module by default, add support for Dediprog SF600 and the new communication protocol of the SF100 with newer firmware.
WCH CH341A
VIA VT8251
Add support to update the firmware of Promise UltraATA controllers

SST SST25WF020A, SST25WF040B, SST25WF080B
Winbond W29C512A/W29EE512
Infrastructural improvements and fixes
Add support for libftdi1 (previous libftdi support still in place for backward compatibility but will eventually be removed)
Add infrastructure for libusb1 and use it for new programmers (existing code will be migrated from libusb0 continuously in the future)
Many cross-platform and cross-architecture improvements:
Fix compilation on OSX and Solaris-based systems
Add support for GNU Hurd
Add support for musl libc
Use nanosleep() instead of usleep() where available (enables building with uclibc)
Support compilation on Android (bionic libc)
Partial architecture support for alpha hppa m68k sh s39
Rigorously check integrity of I/O stream data (e.g. to notice full filesystems when writing flash data to a file)
Add make parameters for easier disabling/enabling of various classes of programmers: CONFIG_NOTHING=yes CONFIG_EVERYTHING=yes CONFIG_ENABLE_LIBUSB0_PROGRAMMERS=no CONFIG_ENABLE_LIBUSB1_PROGRAMMERS=no CONFIG_ENABLE_LIBPCI_PROGRAMMERS=no

changes since 0.9.5:
==User interface changes==
* The -p/--programmer parameter is now mandatory for all operations that access the programmer/chip.
*: Previously there was a default programmer selected at build time. This was convenient for most users, but created a danger for others that increased with the number of platforms and programmers supported, namely that they get used to a default programmer that later changes when they use another binary. It is very easy to brick a mainboard in case you do not notice you are writing its firmware instead of a device attached to an external programmer. The disadvantage is of course that many users have now to add '''-p internal''' to the command line when they want to do ''the obvious'' and flash their mainboards.
* It is now possible to let flashrom create log files directly (by using the new -o/--output option).
* flashrom now checks for duplicate -i/--image arguments (which are used together with layout files).

* The code generating the list of supported hardware for the wiki has been improved.
* Many exit() calls have been replaced by proper error handling.
* I/O permissions are now released automatically on shutdown.
