km/common: implement boardId HWkey checks as u-boot cmd
BoardId and HWKey are used to identify the HW class of a given board. The correct values are stored in the inventory eeprom. During creation time of a boot package the boardId and HWkey for the SW is stored in the default environment and burned into the flash. During boottime the values in the inventory and in the environment are compared to avoid starting of a SW which is not authorized for this board. Some bootpackages are allowed to run on a set of different boardId hwKey. In this case the environment variable boardIdListHex was added to the default environment. In this case the command iterates over the pair values and compares them with the values read from the inventory eeprom. The syntax of such a boardIdListHex value is e.g.: 158_1 159_1 159_2 Signed-off-by: Thomas Herzmann <thomas.herzmann@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com> Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> Acked-by: Heiko Schocher <hs@denx.de> cc: Wolfgang Denk <wd@denx.de> cc: Detlev Zundel <dzu@denx.de>
