Dear maintainer,

The u-boot source code contains non-free software. Here is the list of affected
files:

drivers/usb/host/xhci-rcar-r8a779x_usb3_v3.h
arch/mips/mach-octeon/include/mach/cvmx-pki-cluster.h
arch/x86/dts/microcode/m0130673325.dtsi
arch/x86/dts/microcode/m0130679907.dtsi
arch/x86/dts/microcode/m01406c2220.dtsi
arch/x86/dts/microcode/m01406c3363.dtsi
arch/x86/dts/microcode/m01406c440a.dtsi

arch/x86/dts/microcode/m12206a7_00000029.dtsi
arch/x86/dts/microcode/m12306a2_00000008.dtsi
arch/x86/dts/microcode/m12306a4_00000007.dtsi

arch/x86/dts/microcode/m12306a9_0000001b.dtsi
arch/x86/dts/microcode/m7240651_0000001c.dtsi
arch/x86/dts/microcode/mc0306d4_00000018.dtsi

Note: There is also a proprietary license file present in
"Licenses/r8a799x_usb3.txt".

I've tested locally that removing these files will not break compilation, so I
advise simply removing those files from the repository. But I do not know what
kind of impact this will have on users of the u-boot-tools package.
