A385 BootROM fills into bits [31:28] of register 0x182d0 tracing value, which represents in which state BootROM currently is. BootROM fills one of the possible values: 0x2 (CPU initialization), 0x3 (UART detection), 0x6 (UART booting), 0x8 (PCI Express booting), 0x9 (parallel or SPI NOR booting), 0xA (parallel or SPI NAND booting), 0xB (SATA booting) and 0xE (SD / eMMC booting).
Meaning of these values matches TRACE_* macros from Marvell soc_spec.h file: https://github.com/MarvellEmbeddedProcessors/u-boot-marvell/blob/u-boot-2013...
