Add HP 8300 USDT
Still on Gerrit. ME downloader failed with HP update file, so let's just use Lenovo's instead. Both contain identical ME8_5M_Production.bin files. Tested and working: * Native raminit with both DIMMs * Libgfxinit textmode and framebuffer on both DisplayPorts and VGA * External USB2 and USB3 ports: they all work * USB 3.0 SuperSpeed (rear, 4 ports) * Ethernet * Mini-PCIe WLAN * SATA: 2.5" SSD and optical drive bay * SeaBIOS and GRUB (boot to linux) * PS/2 keyboard and mouse * S3 suspend and resume, wake using USB keyboard * Headphone output, line out, internal speaker * Wake on LAN * Rebooting * CMOS options & nvramcui Untested: * Line in, mic input * MXM graphics card * EHCI debug Not working: * Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so maybe it just isn't present * PS/2 keyboard wake from S3 * mSATA (I have no mSATA drives)

+Subject: [PATCH] Add HP 8300 USDT port
+
+In Coreboot Gerrit:
+https://review.coreboot.org/c/coreboot/+/74906
+
+The following is tested and is working:
+* Native raminit with both DIMMs
+* Libgfxinit textmode and framebuffer on both DisplayPorts and VGA
+* External USB2 and USB3 ports: they all work
+* USB 3.0 SuperSpeed on Linux-libre (rear, 4 ports)
+* Ethernet
+* Mini-PCIe WLAN
+* SATA: 2.5" SSD and optical drive bay
+* Booting Live Linuxes from DVD and USB with SeaBIOS 1.16.1
+* PS/2 keyboard
+* S3 suspend and resume, wake using USB keyboard
+* Headphone output, line out, internal speaker
+* Wake on LAN
+* Rebooting
+* CMOS options & nvramcui
+
+Untested:
+* mSATA slot. The SATA port needs to be enabled on devicetree
+ too, but I'm unable to test due to lack of hardware
+* Line in, mic input
+* MXM graphics card
+* PS/2 mouse
+* EHCI debug
+
+Not working:
+* Mini-PCIe USB: I couldn't get it working on vendor BIOS either, so
+ maybe it just isn't present
+* PS/2 keyboard wake from S3
