For Debian this is:

sudo apt install libssl-dev

You can see all the pre-reqs at [1]

Nothing in particular. At some point if you want to build a particular
U-Boot version from a separate checkout, you can manually replace
U-Boot in coreboot.rom:

# update u-boot
cbfstool $BUILD_DIR/coreboot.rom remove -n fallback/payload || true
cbfstool $BUILD_DIR/coreboot.rom add-flat-binary \
   -f u-boot.bin \
    -n fallback/payload -c LZMA -l 0x1110000 -e 0x1110000

If you want the 64-bit U-Boot then instead of u-boot.bin you need
u-boot-x86-with-spl.bin (and you must use 'make coreboot64_defconfig'
to configure U-Boot). In fact, that option is not available in
coreboot yet, so I should send a patch!
