The NPCD378 can be found on at least:

* HP Compaq 8300
The datasheet is not publicly available, as HP implements lots of
custom hardware. Add basic support for it, based on HP Compaq 8200.
The first eight LDNs seem to be standard nuvoton compatible, except for
LDN4, which is used to control front LED and power in ACPI S3.
LDN8 provides access to HP's proprietary HWM which is accessiable at the LDN's
IOBASE with a size of 0x100 bytes.
The HWM consists of 16 pages with each holding 0xff bytes. The pages can be
selected by writing the page index to IOBASE + 0xff.
TODO:

WARNING:
The remaining LDNs have been guessed and might be wrong!

This is based on the code from the 8470p port. Tested on the quad
core/quad SODIMM version. This laptop uses discrete MXM 3.0b graphics
cards. Tested working with both Quadro K3000M and GTX 980M 8GB. The
laptop must be completely disassembled down to the motherboard to
perform the initial flash, subsequent flashes can be done internally
via flashrom. There is a simple mod that can be performed to make
subsequent external flashes easier in case of a brick, I'll put more
information on this on the wiki later. The lack of an MXM structure
built in to the firmware causes the GPU to enter a mode with nerfed
performance, there is a workaround though, I'll add this to the wiki
as well. I have no info on EHCI debugging.
Tested and working:
- memory: 4G+4G, 4G+4G+4G+4G
- Linux (Debian Stretch with kernel 4.9.0) booted from SeaBIOS payload
with graphics init disabled in coreboot. I allowed SeaBIOS to load the
VBIOS from the MXM.
- WLAN
- keyboard, trackpoint and touchpad
- USB
- serial port on dock
- fan control
- VGA
- DisplayPort
- Audio
- Both HDD SATA ports, ODD SATA, eSATA
- S3 with SeaBIOS 1.11, SERCON must be disabled
- Brightness and volume FN keys
- Mute and calculator hotkeys
- Status LEDs
- Bluetooth
Not working:
- GRUB2 as payload will freeze. Has something to do with at_keyboard
module. The built in keyboard requires this module to function though.
- Sleep FN key
- WiFi toggle and internet browser hotkeys
- S3 fails to resume (restarts) if the laptop is removed from AC power,
or gets unplugged and then plugged back in while suspended. Sleep
status LEDs remain normal during this process.

This commit adds support for describing USB ports in devicetree.cb.
It allows a USB port location to be described in the tree with
configuration information, and ACPI code to be generated that
provides this information to the OS.
A new scan_usb_bus() is added that will scan bridges for devices so
a tree of ports and hubs can be created.
The device address is computed with a 'port type' and a 'port id'
which is flexible for SOC to handle depending on their specific USB
setup and allows USB2 and USB3 ports to be described separately.
For example a board may have devices on two ports, one with a USB2
device and one with a USB3 device, both of which are connected to an
xHCI controller with a root hub:
xHCI
|
RootHub
| |
USB2[0] USB3[2]
device pci 14.0 on
chip drivers/usb/acpi
register "name" = ""Root Hub""
device usb 0.0 on
chip drivers/usb/acpi
register "name" = ""USB 2.0 Port 0""
device usb 2.0 on end
end
chip drivers/usb/acpi
register "name" = ""USB 3.0 Port 2""
device usb 3.2 on end
end
end
end
end
