soc-family.inc: to be included in machine.conf to add SOC_FAMILY to MACHINEOVERRIDE Add a soc-family.inc file that can be included in a machine.conf to enable the use of SOC_FAMILY in MACHINEOVERRIDE, which could be useful to group multiple machines with the same common base. Some examples can be seen in meta-ti BSP layer.

soc-family.inc: Add a default SOC_FAMILY value Otherwise, if MACHINEOVERRIDES is expanded before SOC_FAMILY is set (which may happen as MACHINEOVERRIDES is included in OVERRIDES) we can see: ExpansionError: Failure expanding variable MACHINEOVERRIDES, expression was ${@['', '${SOC_FAMILY}:']['${SOC_FAMILY}' != '']}p1022ds which triggered exception SyntaxError: EOL while scanning string literal (MACHINEOVERRIDES, line 1) To avoid this, give SOC_FAMILY a default empty value so it doesn't get read as None.

soc-family: fix SOC_FAMILY override order * the current order has SOC_FAMILY settings, which are generic settings for a group of devices, overriding the machine specific settings. For example: KERNEL_DEVICETREE_ti33x = "xxxx" KERNEL_DEVICETREE_beaglebone = "yyyy" Should yield "yyyy" when building for the beaglebone because that is a more specific device than ti33x. However, without this change the result is that the value is set to "xxxx" meaning the more generic setting overrides the more specific setting.
