New mainboard: X2E_N150

Patch in Gerrit: https://review.coreboot.org/c/coreboot/+/89281 Not working: USB3 ports only work at USB2 speeds. IFD: Modified the original by: - Removing Device Exp2 region (empty anyway) - Enlarging the BIOS region to use this freed space - Setting the HAP bit in PCHSTRP55 using a fork of me_cleaner: https://github.com/XutaxKamay/me_cleaner Signed-off-by: Riku Viitanen <riku.viitanen@protonmail.com> Signed-off-by: Leah Rowe <leah@libreboot.org>

+Subject: [PATCH 1/1] Add a -p option (skip FPTR checks)
+
+if you pass -k (keep fptr modules), don't use -r, don't
+use -t, you can essentially just use me_cleaner to
+extract a ME image without changing it. this is useful
+when for example, you just want to set the HAP bit.
+
+however, me_cleaner still performs a FPTR check.
+
+on some newer ME versions, it's always invalid according
+to me_cleaner, because for example it doesn't handle
+ME16 very well yet.
+
+this patch adds an option to override the FPTR check
+
+either pass -p or --pass-fptr
