Allows for using hardware watchpoints for 1, 2, 4, 8 byte long addresses. The default configuration of watchpoint is RW but code allows to select RO or WO and X. Since debugging registers are per-CPU (CP14) the watchpoint is set on the CPU that was lucky (or not) to enter DDB. HW breakpoints are used to perform single step in KDB. When HW breakpoint is enabled all watchpoints are temporary disabled to avoid recursive abort on both watchpoint and breakpoint. In case of branch, the breakpoint is set to both - next instruction and possible branch address. This requires at least 2 breakpoints supported in the CPU however this is a must for ARMv6/v7 CPUs.
