### flashrom chip config
We use [flashrom](https://flashrom.org/) for flashing. Run `flashrom -p <your_hardware>`
(for [example](#how-to-flash) `flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=128` for the
Raspberry Pi) to let flashrom detect the chip. It will probably list a few you need to choose
from when flashing (by adding `-c "<chipname>"`). While there might be specific examples
in the commands below, please review the chip model for your device. In case you are
unsure what to specify, here's some examples we find out there:

In case you are unsure what to specify, here's some examples we find out there:
#### 4MB chip
* `MX25L3206E` seems to mostly be in use
#### 8MB chip
* `MX25L3206E/MX25L3208E` is seen working with various X230 models.
* `MX25L6406E/MX25L6408E` is used in [this guide](https://github.com/mfc/flashing-docs/blob/master/walkthrough%20for%20flashing%20heads%20on%20an%20x230.md#neutering-me)
