mb/hp: Add Pro 3500 series (Sandy/Ivy Bridge)
This is another readily available (used market) system.
Based on autoport.
* All peripherals should work.
* Automatic fan control as well as S3 are working.
* The board was tested to boot Linux and Windows. EHCI debug is
untested.
* When using MrChromebox edk2 with secure boot build in, the board will
hang on each boot for about 20 seconds before continuing.
There are some quirks for doing the first flash, see the documentation.

+# HP Pro 3500 Series
+
+This page describes how to run coreboot on the [Pro 3500 Series]
+desktop from [HP].
+
+## State
+
+All peripherals should work. Automatic fan control as well as S3 are
+working. The board was tested to boot Linux and Windows. EHCI debug
+is untested. When using MrChromebox edk2 with secure boot build in, the
+board will hang on each boot for about 20 seconds before continuing.
+With disabled ME, the SuperIO will not get CPU temperatures via PECI and
+therefore the automatic fan control will not increase the fan speed.
+
+## Flashing coreboot
+
+```{eval_rst}
++---------------------+-------------------------+
+| Type | Value |
++=====================+=========================+
+| Socketed flash | No |
++---------------------+-------------------------+
+| Model | W25Q64FVSIG |
++---------------------+-------------------------+
+| Size | 8 MiB |
++---------------------+-------------------------+
+| In circuit flashing | Yes |
++---------------------+-------------------------+
+| Package | SOIC-8 |

+| Write protection | See below |
++---------------------+-------------------------+
+| Dual BIOS feature | No |
++---------------------+-------------------------+
+| Internal flashing | Yes |
++---------------------+-------------------------+
+```
+
+### Flash layout
+The original layout of the flash should look like this:
+```
+00000000:00000fff fd
+00400000:007fffff bios
+00001000:003fffff me
+00fff000:00000fff gbe
+00fff000:00000fff pd
+```
+
+### Internal programming
+
+The SPI flash can be accessed using [flashrom] (although it reports as
+"N25Q064..3E", it works fine).
+
+With a missing FDO jumper, `fd` region is read-only, `bios` region is
+read-write and `me` region is locked. Vendor firmware will additionally
+protect the flash chip. After shorting the FDO jumper (E2) full
+read-write access is granted.
+
+Do **NOT shutdown** the operating system **after flashing** coreboot
+from the vendor firmware! This will brick your device because the bios
+region will be modified on shutdown. Cut the AC power or do a restart
+from the OS.
+
+**Position of FDO jumper (E2) close to the F_USB3**
+![][pro_3500_jumper]
+
+[pro_3500_jumper]: pro_3500_series_jumper.avif
+
+### External programming
+
+External programming with an SPI adapter and [flashrom] does work, but
+it powers the whole southbridge complex. The average current will be
+400mA but spikes may be higher. Connect the power to the flash or the
+programming header next to the flash otherwise programming is unstable.
+The supply needs to quickly reach 3V3 or else the chip is also unstable
+until cleanly power cycled.
+
+**Position of SOIC-8 flash and pin-header near ATX power connector**
