ARMv7-R: Add a configuration to support delayed memory initialization.  This logic was already in place for SDRAM but is also required for some ECC memories as well.

ARMv7-R: Add logic to work-around errata, remove logic to access VBAR since this is no VBAR and add logic to access PMCR.  TMS570: Add logic to set debug bits in PMCR

TMS570:  Memory map applies only to LS04x and LS03x.  Peripheral numbering seems to start with 1, not 0

ARMv7-R: fix some issues to get a clean compilation; TMS570:  Add enough logic to support a minimum build.  Not much there on the initial commit

STM32 QEncoder: Add support for STM32F30xxx

STM32 TIM: Remove some warnings, fix timer resolution bug and cosmetic changes

Rename CONFIG_ARMV7M_MPU to CONFIG_ARM_MPU so that we can reuse the configuration settings for the ARMV7R MPU

STM32: Fix typos in pinmaps

STM32: Fix typos in STM32F30xxx pinmap

Add initial support for ARMv7-R architecture.  Initial commit is largely a clone of ARMv7-A and needs further review

All architectures need to build ELF support if either CONFIG_ELF or CONFIG_MODULE are selected.  Cortex-M7 also must support module cache corherence
