fcup-smsend[mult]: fix buglet in K&R C NULL pointer passing The only 100% safe way to pass a NULL pointer as a function argument in K&R C is to cast 0 to a pointer type; failing to do so may cause mysterious bugs (invalid stack frames or garbage in argument registers) on 64-bit machines. This issue has already been fixed in most of FC host tools, but I just found some missed spots: passing of NULL UDH to PDU encoding functions in fcup-smsend[mult] in the case of single (not concatenated) SMS.

# The following parameters go into the <p command sent to the boot ROM

pll-config 4/1		# 26 MHz in, PLL&DSP @ 104 MHz, ARM @ 52 MHz
rhea-cntl 0x00		# fastest setting, used by OsmocomBB, presumably correct

# The remaining settings are carried out via loadagent commands
init-script pirelli.init

# Flash global config and chip select base addresses
flash dual-8M 0x03000000 0x02000000

# Perform a Iota poweroff when we are done
