## The stack pointer is initialized for use by the remainder of the
## initialization. The linker script defines the initial stack area.
##
## Stacks are always 8-byte aligned. A '0' is stored at the
## stack pointer to indicate the end of the stack chain. Stack frames
## always consist of at least 8 bytes - the backchain pointer and the
## slot above the backchain pointer for the callee's LR.
