This patch implements LD eFuse programming support. Armada 385 contains two
LD eFuse lines, each is 256 bit long with one additional lock bit. LD 0
line is mapped to U-Boot fuse bank 64 and LD 1 line to fuse bank 65. U-Boot
32-bit fuse words 0-8 are mapped to LD eFuse line bits 0-255. U-Boot fuse
word 9 is mapped to LD eFuse line lock bit.
So to program LD 1 General Purpose Data line, use U-Boot fuse command:
=> fuse prog -y 65 0 0x76543210
=> fuse prog -y 65 1 0xfedcba98
=> fuse prog -y 65 2 0x76543210
=> fuse prog -y 65 3 0xfedcba98
=> fuse prog -y 65 4 0x76543210
=> fuse prog -y 65 5 0xfedcba98
=> fuse prog -y 65 6 0x76543210
=> fuse prog -y 65 7 0xfedcba98
=> fuse prog -y 65 8 0x1
