#* DESCRIPTION: Builds the Intermediate Boot Loader (IBL)
#*
#*  Usage:  make c6455 | c6472 | c6474 | c6457 [DEBUG=yes] [ETH=no] [NAND=no]  \
#*          [BIS=no] [COFF=no] [BLOB=no] [ELF=no] [ENDIAN= both | big | little] [I2C_BUS_ADDR= 0x50 | 0x51] \
#*			[COMPACT_I2C=yes]
#*
#* or to make a board specific configuraiton
#*
#*			make evm_c6455 | evm_c6472 | evm_c6474
#*
#* or to test the builds by making all the devices and testing excludes
