edk2-msm uses SimpleInit as boot manager. You can configure it by modifying simpleinit.static.uefi.cfg in logfs partition
SimpleInit will detect Windows automatically, so there’s no need to add Windows boot entry.
Currently only several devices using the Qualcomm Snapdragon 845 (SDM845) SoC support booting Android.
Here is a configuration example for Xiaomi Mix 2s, which has been tested with Evolution X (Android 12)
language = "en_US"
logger {
file_output = "@part_logfs:\\simpleinit.log"
use_console = false
}
boot {
// Default boot option, please remove the `boot.default` key found in `simpleinit.uefi.cfg` first
default = "android"
configs {
// Example of booting to Android
android {
mode = "linux"

show = true
enabled = true

extra {
use_uefi = false
// points to the boot partition in the locates configuration below
abootimg = "#part_boot"
// device model in boot image device tree, varies by device
// might get recognized automatically on certain devices and thus not needed
// read it from /sys/firmware/devicetree/base/model
dtb_model = "Xiaomi Technologies, Inc. Polaris P2 v2.1"
// points to the dtbo partition in the locates configuration below, might not be needed
// dtbo = "#part_dtbo"
// dtbo ID，varies by device, might not be needed
// dtbo_id = 6
}
}
