# Build System Changes for Android.mk Writers
+## PRODUCT_STATIC_BOOT_CONTROL_HAL is obsolete {#PRODUCT_STATIC_BOOT_CONTROL_HAL}
+
+`PRODUCT_STATIC_BOOT_CONTROL_HAL` was the workaround to allow sideloading with
+statically linked boot control HAL, before shared library HALs were supported
+under recovery. Android Q has added such support (HALs will be loaded in
+passthrough mode), and the workarounds are being removed. Targets should build
+and install the recovery variant of boot control HAL modules into recovery
+image, similar to the ones installed for normal boot. See the change to
+crosshatch for example of this:
+
+* [device/google/crosshatch/bootctrl/Android.bp] for `bootctrl.sdm845` building
+ rules
+* [device/google/crosshatch/device.mk] for installing `bootctrl.sdm845.recovery`
+ and `android.hardware.boot@1.0-impl.recovery` into recovery image
