Obvious error not armv7 but armv8！

VIM3
1

Hello，
There is a mistake about the android or ubunut vim3， why its cpu arch is armv7 not armv8？
In fact， if we check the document of arm cpu company， we will find that the arch of cortex a53 and a73 both titled armv8 arch？
How to change the config of vim3 system， then we could get the armv8 cpu info？ And then we will compile the model with armv8 ISA set.
Looking forward to your reply ！

@lcl2020 When you look at the code below, it will answer the questions you ask.
device/khadas/kvim3/BoardConfig.mk

ifneq ($(ANDROID_BUILD_TYPE), 64)
TARGET_CPU_ABI := armeabi-v7a
TARGET_CPU_ABI2 := armeabi
TARGET_CPU_SMP := true
TARGET_ARCH := arm
TARGET_ARCH_VARIANT := armv7-a-neon
TARGET_CPU_VARIANT := cortex-a9
else
TARGET_ARCH := arm64
TARGET_ARCH_VARIANT := armv8-a
TARGET_CPU_VARIANT := generic
TARGET_CPU_ABI := arm64-v8a
TARGET_CPU_SMP := true

TARGET_2ND_ARCH := arm
TARGET_2ND_ARCH_VARIANT := armv7-a-neon
TARGET_2ND_CPU_VARIANT := cortex-a9
TARGET_2ND_CPU_ABI := armeabi-v7a
TARGET_2ND_CPU_ABI2 := armeabi

TARGET_SUPPORTS_32_BIT_APPS := true
TARGET_SUPPORTS_64_BIT_APPS := true
endif

1 so，why not build the android img with 64bit mode？
2 Is there the lastest 64bit mode android img for vim3？
3 You mean the android img released before in fact support both arm64-v8a and arm64-v8a lib？
4 After checking, vim3 is the core of A73, armv8 architecture, but fp16 operation is not supported until armv8.2. If A76 goes up, vim3 should not run fp16. Is the reason ringt for the vim3 feature now?

@lcl2020 VIM3 firmware has been a 32-bit system before. Recently, AMLOGIC finally supports 64 bit systems, and we will release 64 bit firmware in the near future.

Tks，good news for us！
When will it be released？this month or August？
And it will support FP16 operations acceleration at the time ， right？
