## PRODUCT_STATIC_BOOT_CONTROL_HAL is obsolete {#PRODUCT_STATIC_BOOT_CONTROL_HAL}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
