This commit adds two new commands to the serprog protocol which allow more fine grained control over the SPI bus. This enables more applications over serprog like e.g. flashing AVR microcontrollers. This can be tried with my forks of pico-serprog: https://github.com/funkeleinhorn/pico-serprog/tree/spimode and avrdude: https://github.com/funkeleinhorn/avrgirl/tree/serprog-programmer I announced this change in flashrom and flashprog IRC channels and got overall positive feedback in the flashprog channel. The same changes will be sent to flashprog to prevent diverging specs.

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 supports building with **make** and **meson**.
TLDR, building with meson
"""""""""""""""""""""""""
::
meson setup builddir
meson compile -C builddir
meson test -C builddir
meson install -C builddir
