[Mtk][N0]客制化签名文件

1、make key

按 alps\build\target\product\security\README 文件内容指示

The following commands were used to generate the test key pairs:

  development/tools/make_key testkey  '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
  development/tools/make_key platform '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
  development/tools/make_key shared   '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'
  development/tools/make_key media    '/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com'

各参数说明如下：

Attrs	Description	Example
C	Country Name	US
ST	State or Province Name	California
L	Locality Name	Mountain View
O	Organization	Google
OU	Organizational Unit Name	Android
CN	Common Name	Android
emailAddress	Contact email address	android@android.com

2、替换旧 key

然后将生成的签名文件

拷贝到 alps\device\mediatek\common\security\project\ 替换原文件。

3、开宏开关

到 ProjectConfig.mk 里面开启 MTK_SIGNATURE_CUSTOMIZATION = yes。
若宏开关为关闭状态，则使用的时 alps\build\target\product\security\ 下的签名文件。
