This makes flashrom sleep more eagerly rather than busy-waiting, observing that most delays in flashrom are either less than 100 microseconds (barely enough time to get any work done, even on a fast machine) or much more than 1 millisecond (very wasteful to busy-loop). Since we believe most systems offer good timer resolution that should provide sleep latency on the order of 100 microseconds, this is a reasonable default. For DOS, the default is set to 50ms because the best available timing source on DOS only ticks at about 20 Hz.

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
