Added code for reading and writing Mac addresses to/from ID EEPROM(0x57). With attached patch, we can use command "mac/mac read/mac save/" to read and write EEPROM under u-boot prompt. U-boot will calculate the checksum of EEPROM while bootup, if it is right, then u-boot will check whether the mac address of eTSEC0/1/2/3 is availalbe (non-zero). If there is mac address availabe in EEPROM, u-boot will use it, otherewise, u-boot will use the mac address defined in MPC8641HPCN.h. This matches the requirement to set unique mac address for each TSEC port.

The device tree image is assumed to be uncompressed in the image file. We automatically allocate space for the device tree in memory and provide an 8k pad to allow more than a reasonable amount of growth. Additionally, a device tree that was contained in flash will now automatically get copied to system memory as part of boot. Previously an error was reported if one tried to boot a device tree that was in flash.
