Board-specific package - possible?

Hi, I would like to make a package specific to a particular board (the package would contain a script for SIM switching).

I see there a packages which are platform-specific (RPi ones), but what I need is just a single board dependency:

github.com

openwrt/openwrt/blob/cecb0ccfbf08c7fbcc74da860df1e20016a4b9de/target/linux/bcm27xx/modules/other.mk#L13


      
          # Copyright (C) 2019 OpenWrt.org
          
          
define KernelPackage/pwm-raspberrypi-poe
            SUBMENU:=$(OTHER_MENU)
            TITLE:=Raspberry Pi Firwmware PoE Hat PWM support
            KCONFIG:= \
              CONFIG_PWM=y \
              CONFIG_PWM_RASPBERRYPI_POE
            FILES:=$(LINUX_DIR)/drivers/pwm/pwm-raspberrypi-poe.ko
            AUTOLOAD:=$(call AutoLoad,20,pwm-raspberrypi-poe)
            DEPENDS:=@TARGET_bcm27xx @LINUX_5_15 +kmod-hwmon-pwmfan
          endef
          
          
define KernelPackage/pwm-raspberrypi-poe/description
            This package provides Raspberry Pi Firwmware PoE Hat PWM support
          endef
          
          
$(eval $(call KernelPackage,pwm-raspberrypi-poe))
          
          

          
define KernelPackage/smi-bcm2835

Is it possible to do?

No, that's not possible to express with packaging metadata. The closest you can get, would be depending on the target - and then bailing out in the executable, in case it's executed on a non-compatible device. This way you can prevent potentially harmful operations on different devices, leaving 'wasting' some space on the overlay the worst that could happen, if users decide to install the package nevertheless.
