+Nordic nRF boards (``microbit``)
+================================
+
+The `Nordic nRF`_ chips are a family of ARM-based System-on-Chip that
+are designed to be used for low-power and short-range wireless solutions.
+
+.. _Nordic nRF: https://www.nordicsemi.com/Products
+
+The nRF51 series is the first series for short range wireless applications.
+It is superseded by the nRF51 series.
+The following machines are based on this chip :
+
+- ``microbit`` BBC micro:bit board with nRF51822 SoC
+
+There are other series such as nRF52, nRF53 and nRF91 which are currently not
+supported by QEMU.
+
+Supported devices
+-----------------
+
+ * ARM Cortex-M0 (ARMv6-M)
+ * Serial ports (UART)
+ * Clock controller
+ * Timers

I'd use "ihex format" instead of "hexadecimal format", see
https://en.wikipedia.org/wiki/Intel_HEX
and also commit e4a25ed91947af1ec87f23725de4ac86a3353b48:
loader: Implement .hex file loader
This patch adds Intel Hexadecimal Object File format support to the
generic loader device. The file format specification is available
here: http://www.piclist.com/techref/fileext/hex/intel.htm
This file format is often used with microcontrollers such as the
micro:bit, Arduino, STM32, etc. Users expect to be able to run .hex
files directly with without first converting them to ELF. Most
micro:bit code is developed in web-based IDEs without direct user
access to binutils so it is important for QEMU to handle this file
format natively.
Otherwise:

Just noticed a typo here, it's "superseded by the nRF52 series". I will
fix this in next version of this patch.

I was not aware of the name of the format. I will apply the change and
add a link to the Wikipedia page of Intel HEX.
