Notes for mi8916 target

• The target may boot only on Redmi 2 (wt88047) as of now.
• The target uses SD card for /data mountpoint. Make sure to have a SD card with 2 GB size at minimum inserted.

Notes for tiare_mainline target

• The device has recovery partition sized at 25 MB which is too small to hold recovery.img built from the target. To boot the recovery.img, flash the image to boot partition and continue with normal boot.
• The target is 32-bit, which requires the following changes to be made in AOSP tree in order to boot:
  1. On packages/modules/Connectivity/bpf/loader/NetBpfLoad.cpp, locate to the next line of the line containing [Arm] 64-bit userspace required on 6.2+ kernels (%d). (which should be return 1;), remove the line.
  2. On system/netd/server/XfrmController.cpp, in function validateResponse, replace the return statement containing Error netlink message with return netdutils::status::ok;.
