The patch adds new functionality to the test: tracking the areas of chip memory that were modified (i.e. by erase or write operation), and then checking those areas were completely covered by verify operation. The test operates over the mock chip memory of 16 bytes, so it is possible to track each byte which was modified, and assert that is has been verified afterwards. Adding the test found a bug which is fixed in this commit: Post-cleanup after processing unaligned region for the case when end region needs to be extended to align with erase block. Writing was done correctly, but post-processing of newcontents could cause one-off offset at the end of the region, which would make verification appear false-negative (see test cases #16-19).

flashrom README
===============
flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.
Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.
Please make a backup of your flash chip before writing to it.
Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
Building / installing / packaging
---------------------------------
flashrom is built with **meson**. TLDR:
::
meson setup builddir
meson compile -C builddir
meson test -C builddir
meson install -C builddir
