[PATCH RFC u-boot-mvebu 4/6] arm: mvebu: Define all options for A38x BOOT_FROM_* macros

[Pali Rohár]

Disassembling A385 BootROM binary reveal how BootROM interprets strapping
pins for Boot Device Mode. All possible options are:

0x00..0x07 -> Parallel NOR
0x08..0x15 -> Parallel NAND
0x16..0x17 -> Parallel NOR
0x18..0x25 -> Parallel NAND
0x26..0x27 -> SPI NAND
0x28..0x29 -> UART xmodem
0x2a..0x2b -> SATA
0x2c..0x2d -> PCI Express
0x2e..0x2f -> Parallel NOR
0x30..0x31 -> SD / eMMC
0x32..0x39 -> SPI NOR
0x3a..0x3c -> Parallel NOR
0x3d..0x3e -> UART debug console
0x3f       -> Invalid

Note that Boot Device Mode Options in A38x Hardware Specifications is
incomplete.
