# 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## PRODUCT_STATIC_BOOT_CONTROL_HAL is obsolete {#PRODUCT_STATIC_BOOT_CONTROL_HAL}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

## Deprecation of `BUILD_*` module types
See [build/make/Deprecation.md](Deprecation.md) for the current status.
