arch/arm/src/tiva/hardwar: Move LM3S and LM4F include files to hardware/lm/ sub-directory. Move all TM4C header files files to hardware/tm4c/ sub-directory.
arch/arm: Add basic configuration/build support for CC13xx parts. Conditioned on EXPERIMENTAL.
Squashed commit of the following:
arch/arm/src/tiva/Make.defs: Trivial change to conditional VPATH.
arch/arm/src/tiva: Move LM3S and LM4F source files to lm/ sub-directory. Move all TM4C source files to tm4c sub-directory.
arch/arm/src/tiva and configs/: Change include patch from chip/ to hardware/ in all Tiva files includes.
arch/tmp/src: Rename chip/ subdirectory to hardware/. This is a better name since it does not conflict with other directory names and, well, we are going to be change a lot of the Tiva directory structure in the next few commits.
This makes the user interface a little hostile. People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header). A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length. Instead, we define the packet buffer size then derive the MTU.
The MTU is not common currency in networking. On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP). Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes. So we should be all good and without the recurring 14 byte error in MTU's and MSS's.
Squashed commit of the following:
Trivial update to fix some spacing issues.
net/: Rename several macros containing _MTU to _PKTSIZE.
net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU. These are not the MTU which does not include the size of the link layer header. These are the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE. This is not the MTU which does not include the size of the link layer header. This is the full size of the packet buffer memory (minus any GUARD bytes).
net/: Rename the file d_mtu in the network driver structure to d_pktsize. That value saved there is not the MTU. The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header. The MTU does not include the link layer header.
arch/arm: Remove support for CONFIG_ARMV7M_CMNVECTOR. It is now the only vector support available. Also remove CONFIG_HAVE_CMNVECTOR. That no longer signifies anything."
arch/arm/src/stm32: This commit removes support for the dedicated vector handling from the STM32 architecture support. Only common vectors are now supported.

Fix some spacing
arch/arm/src/tiva: Verify that the EEPROM driver at least builds.
arch/arm/src/tiva: Move unused function added to tm4c129_syscontrol.c to tiva_eeprom.c where it is actually used.
arch/arm/src/tiva: Reorganize EEPROM register definitions so that the file organization is more like other platforms.
arch/arm/src/tiva: Trying to resolve EEPROM register addressing. Still some issues.
arch/arm/src/tiva: Ran uncrustify on tiva_eeprom.c
arch/arm/src/tiva: EEPROM driver is a little closer to coding standard. Still a way to go.
Author: Shirshak Sengupta <sgshirshak@gmail.com>
arch/arm/src/tiva: Implemented EEPROM driver in compliance with MTD driver as provided by NUTTX for TM4C1294. The EEPROM driver needs to be initialized by calling the function tiva_EEPROMInit The EEPROM driver currently supports only two functionalities - read bytes(multiple of 4) and write bytes (multiple of 4). Note - Rest of the features of EEPROM will be implemented in the future.
