Recently Android Bionic LibC got sys/io.h. Use this header to access ioperm(). Use Assembly for I/O, as Bionic does not have inb(), outb(), etc. Tested on Android 14 by adding flashrom and pciutils as external repositories, adding Android.bp blueprints (Android specialized build system - Soong), building, running and accessing (read, erase, write) SPI flash on x86 device.

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
For full detailed instructions, follow the information in
:doc:`dev_guide/building_from_source`
TLDR, building with make
""""""""""""""""""""""""
::
make
make install
