+Patch to support NVMe and RVVM board properly in U-Boot
+ - Enables NVMe PCI support & booting from it
+ - Enables framebuffer driver, passes it as EFI FB
+ - Enables Realtek RTL8169 driver
+ - Get rid of DHCP boot, it is confusing and not helpful
+
+Applies cleanly over U-Boot 2023.4
+Reuses QEMU virt board config, build like this:
+ make qemu-riscv64_smode_defconfig
+ CROSS_COMPILE=riscv64-linux-gnu- make
+
+Resulting firmware works fine on both RVVM and QEMU
