* Add assert() for debug assertionsSimon Glass2011-09-10-5/+0
| | | | | | | | | | | | | | | assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these. Build errors exposed by this change (and defining DEBUG) are also fixed in this patch. Signed-off-by: Simon Glass <sjg@chromium.org>
