Add mkimage support for generating and verifying MXS bootstream. The implementation here is mostly a glue code between MXSSB v0.4 and mkimage, but the long-term goal is to rectify this and merge MXSSB with mkimage more tightly. Once this code is properly in U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage support. Note that the mxsimage generator needs libcrypto from OpenSSL, I therefore enabled the libcrypto/libssl unconditionally. MXSSB: http://git.denx.de/?p=mxssb.git;a=summary The code is based on research presented at: http://www.rockbox.org/wiki/SbFileFormat Signed-off-by: Marek Vasut <marex@denx.de> Cc: Tom Rini <trini@ti.com> Cc: Fabio Estevam <fabio.estevam@freescale.com> Cc: Stefano Babic <sbabic@denx.de> Cc: Otavio Salvador <otavio@ossystems.com.br>
