Add mx6solo/mx6duallite support

This series goal is to add support for mx6solo and mx6duallite variants of mx6qsabrelite board. The new targets are called mx6ssabrelite and mx6dlsabrelite.

The 1st 16 patches perform cleanup on imximage

The final 2 patches add support for expressions to mkimage. If found not to be worth the effort, they can be omitted.

Troy Kisky (32):
imximage: check dcd_len as entries added
imximage: remove redundant setting of app_dest_ptr
imximage: move flash_offset check to common location
imximage: fix size of image to load.
imximage: delay setting of image size
imximage: change parameters to set_imx_hdr
imximage: make set_imx_hdr_v1/v2 easier to read
imximage: make header variable length
imximage: remove static imximage_version
imximage: prepare to move static variables to struct data_src
imximage: change parameters for set_dcd_val/set_imx_hdr
imximage: move set_imx_hdr to struct data_src
imximage: move set_dcd_val to struct data_src
imximage: enable word writes for version2 header
tools: add parse_helper file
imximage: use parse_helper functions
imximage.cfg: run files through C preprocessor mx6q_4x_mt41j128.cfg: use symbols instead of hardcoded constants mx6q_4x_mt41j128.cfg: add comments mx6q_4x_mt41j128.cfg: use ddr3 mode for reset mx6q_4x_mt41j128.cfg: skip initiailizing non-existent memory mx6q_4x_mt41j128.cfg: force ZQ calibration
mx6: soc: update get_cpu_rev and get_imx_type for mx6solo/sololite
mx6: use CONFIG_MX6 instead of CONFIG_MX6Q
imx-common: cpu: add imx_ddr_size

mx6qsabrelite: add support for mx6 solo/duallite mx6q_4x_mt41j128.cfg: add mx6 solo/duallite support
Add boards for sabrelite variants mx6s(solo) and mx6dl(duallite)
mx6qsabrelite: change CONFIG_SYS_PROMPT
parse_helper: add expression evaluation
imx-mkimage.h: use base + offset syntax
