QC: 如何產生update.zip for recovery

環境布建與假設:
mainchip: QC8974
HLOS: /qc8974
NonHLOS:  /qc8974_bin

step1: build HLOS code
        cd QC8974 && ./build.sh msm8974

step2: create packages
        make target-files-package

step3: copy all mbn from NonHLOS to /qc8974/out/target/platform/msm8974/obj/PACKAGING/target_files_intermediates/msm8974-target_files-eng.root/RADIO  (我是以root的身分build的)
        依NonHLOS 的 contents.xml中的說明copy 有列出的mbn檔就可以了,
        我是copy了:
                   adsp_proc/obj/qdsp6v5_ReleaseG/*.mbn
                   boot_images/build/ms/bin/8974/*.mbn
                   debug_image/build/ms/bin/AAAxxx/*.mbn
                   modem_proc/build/ms/bin/AAAxxx/*.mbn
                   rpm_proc/build/ms/bin/AAAxxx/rpm.mbn
                   trustzone_images/build/ms/bin/AAAxxx/*.mbn
                   wcnss_proc/build/ms/bin/8974/reloc/wcnss.mbn
                   LINUX/android/out/target/product/msm8974/emmc_appsboot.mbn
                   boot_images/build/ms/bin/EMMCBLD/8974_msimage.mbn

step 4: zip all images
        cd /qc8974/out/target/platform/msm8974/obj/PACKAGING/target_files/intermediates/msm8974-target_files-eng.root/
        zip -qry target_updates.zip

step 5: create update.zip package for recovery
        cd /qc8974
        ./build/tools/releasetools/ota_from)target)files 0p out/host/linux-x86 -k build/target/product/security/testkey -d MMC -v out/target/platform/msm8974/obj/PACKAGING/target_files/intermediates/msm8974-target-files-eng.root/target_updates.zip update.zip

step 6: copy update.zip 到sdcard或usb 由手機直接update 或是放到PC用ADB更新
