Subject: board:samsung:common: set envs with board unified information
X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=eee2fab0bddb2c460a96a943d7ed6b0f3718f0fd;p=u-boot.git

board:samsung:common: set envs with board unified information

This patch sets envs that describe board information.
The following envs are set: soc_id, soc_rev, board_rev.
Based on this information, if CONFIG_OF_LIBFDT is enabled,
the 'fdtfile' env is set as:
fdtfile=${soc_family}${soc_id}-${board}.dtb

The generated envs are intenionally not saved to persistent storage.
