【TZ】新增TZ app, steps to add a new TZ app

Please replace myapp/MYAPP with your application name:

1.  cd your TZ root.
2.  mkdir -p trustzone_images/core/bsp/trustzone/qsapps/myapp/build
3.  cp trustzone_images/core/bsp/trustzone/qsapps/sampleapp/build/SConscript trustzone_images/core/bsp/trustzone/qsapps/myapp/build/SConscript
4.  Edit trustzone_images/core/bsp/trustzone/qsapps/myapp/build/SConscript
            Replace all occurrences of smapleapp and SAMPLEAPP with myapp and MYAPP, respectively.
            Remove all aliases except 'myapp' and 'all'.
    
    and (also for 8996,  replace smplap32 as myapp) 
  
5.  Edit trustzone_images/core/securemsm/trustzone/qsapps/libs/applib/proxy/build/SConscript:
            Add 'MYAPP_IMAGE' to env.AddBinaryLibrary(
    copy
    trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\proxy\build\sampleapp
    to
    trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\proxy\build\myapp

6.  Edit trustzone_images/core/securemsm/trustzone/qsapps/libs/applib/qsee/build/SConscript:
        Add the following lines:

    env.AddBinaryObject('MYAPP_IMAGE', IMG_ENTRY_SOURCES)

    env.AddBinaryLibrary('MYAPP_IMAGE', '${BUILDPATH}/tzapp_entrylib', LIB_ENTRY_SOURCES)
    if for GP apps:
    env.AddBinaryObject('MYAPP_IMAGE', IMG_ENTRY_SOURCES)
    
env.AddBinaryLibrary('MYAPP_IMAGE', '${BUILDPATH}/gpapp_lib', LIB_ENTRY_SOURCES_FOR_GP_APPS)

        Add the following to the if-else block:
            elif env.has_key('MYAPP_IMAGE'):
          LIB_ENTRY_SOURCES += [ '${BUILDPATH}/src/tzapp_lib_main.c',]

    copy
    trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\qsee\build\sampleapp
    to
    trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\qsee\build\myapp

7.  do same edit with step6 in Edit trustzone_images/core/securemsm/trustzone/qsapps/libs/applib/qsee64
    (only for 8996 now, and need to use MYAPP64 like SAMPLEAPP64 in SConscript)

8.  If you wish to use libstd (which includes string functions) in your application, edit trustzone_images/core/kernel/libstd/build/SConscript:
        Add 'MYAPP_IMAGE' to env.AddBinaryLibrary()

      And copy 
    trustzone_images/core/kernel/libstd/build/sampleapp 
    to
        trustzone_images/core/kernel/libstd/build/myapp

9.  If you wish to use secrsa in your application, edit trustzone_images/core/securemsm/secrsa/build/SConscript:
        Add the following lines:
            if env.has_key('MYAPP_IMAGE'):
          env.Append(CPPPATH = "${COREBSP_ROOT}/securemsm/secrsa/env/sampleapp/inc")
          env.Append(CPPPATH = "${COREBSP_ROOT}/securemsm/secmath/env/sampleapp/inc")
          env.Append(CPPPATH = "${COREBSP_ROOT}/api/securemsm/trustzone/qsee")
          env.Append(CPPPATH = "${COREBSP_ROOT}/api/securemsm/crypto")
        Add the following to the if-else block:
            elif env.has_key('MYAPP_IMAGE'):
                env.Append(CCFLAGS = "-O3 -OTime ")

10. For TZ.BF.3.0 and beyond:
trustzone_images\core\securemsm\trustzone\qsee\mink\libstd\build\SConscript  (follow the example of sampleapp)
      And copy 
    trustzone_images\core\securemsm\trustzone\qsee\mink\libstd\build\sampleapp 
    to
        trustzone_images\core\securemsm\trustzone\qsee\mink\libstd\build\myapp 

11. trustzone_images/core/bsp/trustzone/qsapps/build/secimage.xml
Follow the example of sampleapp and remember to have the same app_id as you put in
    trustzone_images/core/bsp/trustzone/qsapps/build/signingattr_qpsa.cfg.template

12. for 8996 only
   Edit trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\common_applib\build\SConscript:
  (follow the example of sampleapp)

   And copy 
    trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\common_applib\build\sampleapp 
    to
        trustzone_images\core\securemsm\trustzone\qsapps\libs\applib\common_applib\build\myapp 
   
13. mkdir trustzone_images/core/securemsm/trustzone/qsapps/myapp
    cd trustzone_images/core/securemsm/trustzone/qsapps/myapp
    mkdir build src
    cp ../sampleapp/build/sampleapp.scl build/myapp.scl
      (for 8996) cp ../sampleapp/build/sampleapp.ld build/myapp.ld
    cp ../sampleapp/build/SConscript build/
    Edit build/SConscript
        Replace smapleapp with myapp.
        Update the sources and env.PublishPrivateApi according to your needs.
   Create your c files (e.g. main_app.c) at src directory. 

14. build your app:
   for 8996:
       trustzone_images\build\ms\build.cmd CHIPSET=msm8996 devcfg myapp
   for 8939/52/56/76/92/94:
       trustzone_images\build\ms\build_qsapps.cmd CHIPSET=<chipset> myapp
