hexdump and hexdump32 do similar things, but hexdump32 is mostly a reimplementation that has additional support to configure the console log level, but has a very unexpected len parameter that isn't in bytes, but in DWORDs. With the move to hexdump() the console log level for the hexdump is changed to BIOS_DEBUG.
