The supported format specifiers are %c, %s, %u/%d and %x.
+config PANIC_HANG
+ bool "Do not reset the system on fatal error"
+ help
+ Define this option to stop the system in case of a fatal error,
+ so that you have to reset it manually. This is probably NOT a good
+ idea for an embedded system where you want the system to reboot
+ automatically as fast as possible, but it may be useful during

If this variable is defined, U-Boot is linked against the
size-constrained envrionments even this may be too big. Enable this
option to reduce code size slightly at the cost of some speed.
+config TPL_TINY_MEMSET
+ bool "Use a very small memset() in TPL"
+ help
+ The faster memset() is the arch-specific one (if available) enabled
+ by CONFIG_USE_ARCH_MEMSET. If that is not enabled, we can still get
+ better performance by writing a word at a time. But in very
+ size-constrained envrionments even this may be too big. Enable this
