Summarize most ARM11 and Cortex-A8 updates as "acting much more
like other ARMs", and mention code sharing.
Clarify a few other points, including support for "reset-assert"
on all ARMs except Cortex-M (which doesn't exactly need it).

ARM
+ - supports "reset-assert" event (except on Cortex-M3)
- renamed "armv4_5" command prefix as "arm"
- recognize TrustZone "Secure Monitor" mode
- "arm regs" command output changed
- register names use "sp" not "r13"
- add top-level "mcr" and "mrc" commands, replacing
various core-specific operations

Cortex-M3
- Exposed DWT registers like cycle counter
- vector_catch settings not clobbered by resets
