[Marek Vasut <marex@denx.de>]

Dear Fabio Estevam,

> bootstream) the following build error is seen when doing a MAKEALL build:
> 
> $ ./MAKEALL mx28evk
> Configuring for mx28evk - Board: mx28evk, Options: ENV_IS_IN_MMC
> mxsimage.c:18:25: fatal error: openssl/evp.h: No such file or directory
> 
> Add an entry about the need of installing the 'libssl-dev' package.

> Changes since v2:
> - Use "Debian-based"
> Changes since v1:
> - Do not remove the 'elftosb' text.
