Now all linker symbols are declared as type char[]. Though we can reference the address via both the array name 'var' and its address '&var'. It's better to unify them to avoid confusing developers. This patch converts all '&var' linker symbol refrences to the most commonly used format 'var'. Signed-off-by: Shiji Yang <yangshiji66@outlook.com> Reviewed-by: Tom Rini <trini@konsulko.com>
