[U-Boot] ELPPC board: build warnigns

[Wolfgang Denk]

Dear Frank,

the ELPPC throws a build warning:

misc.c: In function 'misc_init_r':
misc.c:120:3: warning: dereferencing type-punned pointer will break
strict-aliasing rules [-Wstrict-al


Is it still worth to fix this (then please provide a patch), or
should we rather drop that board?

Best regards,

Wolfgang Denk

A stone was placed at a ford in a river with the inscription:
"When this stone is covered it is dangerous to ford here."
