Subject: Pack META/ab_partitions.txt when using the A/B OTA updater.
X-Git-Tag: android-x86-7.1-r1~608^2~19^2~98^2^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=8925d334c3d9932526242ad78ec7a0c23627c3a8;p=android-x86%2Fbuild.git

Pack META/ab_partitions.txt when using the A/B OTA updater.

The list of A/B partitions updated is product-specific. Normally you
would update boot and system, but the product could require to update
other partitions during a system update. This patch packages the list
of A/B partitions configured to be updated when using the A/B updater.
The list can be set in the product makefile by setting the make
variable UPDATE_AB_PARTITIONS.

Bug: 24387863
Test: `make dist` creates the META/ab_partitions.txt in the target_files.zip
