ICS以后的版本没有ATV feature，如何开启ATVfeature

1、ICS.MP.V2.2之前的版本，自行打开ATV feature，会导致以下build error:
No rule to make target
`out/target/common/obj/JAVA_LIBRARIES/com.mediatek.atv.adapter_intermediat
es/javalib.jar', needed by
`out/target/common/obj/APPS/MATVEM_intermediates/classes-full-debug.jar'.
Stop
在这种情况下要做如下事情：
A、确认
alps/vendor/mediatek/project/artifacts/out/target/common/obj/JAVA_LIBRARIE
S下面是否有com.mediatek.atv.adapter_intermediates/javalib.jar文件
B、 如果有则申请patch: ALPS00275315
C、 如果没有，则申请patch：ALPS00275315，并在note里面明确说明附带要release
alps/vendor/mediatek/project/artifacts/out/target/common/obj/JAVA_LIBRARIE
S/ com.mediatek.atv.adapter_intermediates/javalib.jar文件
D、拿到patch后在alps\mediatek\config\$(project)\ProjectConfig.mk文件里面开启
ATV feature的配置即可
2、对于ICS.MP.V2.2以后或者ICS2.MP、JB.MP的版本，不需要打patch，只需要在
alps\mediatek\config\$(project)\ProjectConfig.mk文件中做如下ATV feature配置即
可
HAVE_MATV_FEATURE = yes
mtk_ATV_CHIP = MTK_MT5193
MTK_MATV_ANALOG_SUPPORT = no #如果ATV audio走PWM，则配置成yes
CUSTOM_HAL_MATV = matv
CUSTOM_KERNEL_MATV = mt5193
