Most of these seem to be for other architectures besides ARM/RISC-V. My guess would be keep *arm*/*aarch64*, keymaps, npcm7xx_bootrom.bin, efi-* and linuxboot*/multiboot*. That should ensure that everything works for you, but I'm just guessing here. > -rw-r--r-- 1 ilg staff 78680 Jan 7 14:50 > opensbi-riscv32-generic-fw_dynamic.bin > -rw-r--r-- 1 ilg staff 727464 Jan 7 14:50 > opensbi-riscv32-generic-fw_dynamic.elf > -rw-r--r-- 1 ilg staff 75096 Jan 7 14:50 > opensbi-riscv64-generic-fw_dynamic.bin > -rw-r--r-- 1 ilg staff 781264 Jan 7 14:50 > opensbi-riscv64-generic-fw_dynamic.elf If you want to boot Linux on RISC-V QEMU you will need OpenSBI. You can either use these or build and supply your own binaries. > -rw-r--r-- 1 ilg staff 153728 Jan 7 14:50 palcode-clipper > -rw-r--r-- 1 ilg staff 9882 Jan 7 14:50 petalogix-ml605.dtb > -rw-r--r-- 1 ilg staff 8161 Jan 7 14:50 petalogix-s3adsp1800.dtb > -rw-r--r-- 1 ilg staff 1536 Jan 7 14:50 pvh.bin > -rw-r--r-- 1 ilg staff 67072 Jan 7 14:50 pxe-e1000.rom > -rw-r--r-- 1 ilg staff 61440 Jan 7 14:50 pxe-eepro100.rom > -rw-r--r-- 1 ilg staff 61440 Jan 7 14:50 pxe-ne2k_pci.rom > -rw-r--r-- 1 ilg staff 61440 Jan 7 14:50 pxe-pcnet.rom > -rw-r--r-- 1 ilg staff 61440 Jan 7 14:50 pxe-rtl8139.rom > -rw-r--r-- 1 ilg staff 60416 Jan 7 14:50 pxe-virtio.rom > -rw-r--r-- 1 ilg staff 65536 Jan 7 14:50 qboot.rom > -rw-r--r-- 1 ilg staff 154542 Jan 7 14:50 qemu-nsis.bmp > -rw-r--r-- 1 ilg staff 18752 Jan 7 14:50 qemu_vga.ndrv > -rw-r--r-- 1 ilg staff 50936 Jan 7 14:50 s390-ccw.img > -rw-r--r-- 1 ilg staff 79688 Jan 7 14:50 s390-netboot.img > -rw-r--r-- 1 ilg staff 4096 Jan 7 14:50 sgabios.bin > -rw-r--r-- 1 ilg staff 2528128 Jan 7 14:50 skiboot.lid > -rw-r--r-- 1 ilg staff 991744 Jan 7 14:50 slof.bin > -rw-r--r-- 1 ilg staff 401308 Jan 7 14:51 trace-events-all > -rw-r--r-- 1 ilg staff 524288 Jan 7 14:50 u-boot-sam460-20100605.bin > -rw-r--r-- 1 ilg staff 421720 Jan 7 14:50 u-boot.e500 > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-ati.bin > -rw-r--r-- 1 ilg staff 28672 Jan 7 14:50 vgabios-bochs-display.bin > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-cirrus.bin > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-qxl.bin > -rw-r--r-- 1 ilg staff 28672 Jan 7 14:50 vgabios-ramfb.bin > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-stdvga.bin > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-virtio.bin > -rw-r--r-- 1 ilg staff 39424 Jan 7 14:50 vgabios-vmware.bin > -rw-r--r-- 1 ilg staff 38912 Jan 7 14:50 vgabios.bin Not sure about these, you probably don't need them though (again, just a guess) Alistair > > >
