Fix the following warning:
mpc8323erdb.c: In function 'mac_read_from_eeprom':
mpc8323erdb.c:198:3: warning: dereferencing type-punned pointer will break
strict-aliasing rules [-Wstrict-aliasing]
if (crc32(crc, buf, 24) == *(unsigned int *)&buf[24]) {
^
Size remains unchanged after and before fix:
text data bss dec hex filename
206977 18748 23344 249069 3cced ./u-boot
Note the fix is the crudest possible, but also least intrusive.
