I don't use u-boot, but I saw the powerpc bulk failing to package
u-boot for rk356x and rk3588.  This diff fixes the failures by adding
5 endian swaps.  I don't know if my u-boot works, but I picked 2
boards (1 from each package) and compared u-boot-rockchip.bin between
powerpc and amd64: cmp -l|wc -l found 106 to 117 different bytes.

Right now, powerpc is the only big-endian arch that can build this.
mips64 and powerpc64 are missing devel/arm-none-eabi/gcc,aarch64; and
sparc64 has BROKEN-sparc64 on u-boot.  My 750 MHz PowerPC G4 takes
over 3+1/2 hours to package rk3588 and over 7+1/2 hours for rk356x.

May I get an ok from arm64 people?
