mainboard: Add HP EliteBook 2560p

Most of the code is generated by autoport. The laptop works well under
coreboot with SeaBIOS 1.13.0 payload, running Arch Linux with kernel
5.4.39 and 5.6.11.

+# HP EliteBook 2560p
+
+This page is about the notebook [HP EliteBook 2560p].
+
+## Release status
+
+HP EliteBook 2560p was released in 2011 and is now end of life.
+It can be bought from a secondhand market like Taobao or eBay.
+
+## Required proprietary blobs
+
+The following blobs are required to operate the hardware:
+1. EC firmware
+2. Intel ME firmware
+
+EC firmware can be retrieved from the HP firmware update image, or the firmware
+backup of the laptop. EC Firmware is part of the coreboot build process.
+The guide on extracting EC firmware and using it to build coreboot is in
+document [HP Laptops with KBC1126 Embedded Controller](hp_kbc1126_laptops).
+
+Intel ME firmware is in the flash chip. It is not needed when building coreboot.
+
+## Programming
+
+The flash chip is located between the memory slots and the PCH,
+covered by the base enclosure, which needs to be removed according to
+the [Maintenance and Service Guide] to access the flash chip. An SPI
+flash programmer using 3.3V voltage such as a ch341a programmer, and
+an SOIC-8 clip can be used to read and flash the chip in-circuit.
+
+Pin 1 of the flash chip is at the side near the PCH.
+

+
+For more details have a look at the general [flashing tutorial].
+
+## Debugging
+
+The board can be debugged with EHCI debug. The EHCI debug port is the back
+bottom USB port.
+
+Schematic of this laptop can be found on [Lab One].
+
+## Test status
