The ARMV7-A toolchains are capable to compile binaries for ARMv8-A CPU
in AArch32 execution state.
This adds the BR2_ARM_CPU_ARMV8A option in the 'conditions' to allow
ARMV8-A CPU such as Cortex-A53 or Cortex-A72 to use ARMV7-A toolchains.

Hello,
In an attempt to move the Raspberry defconfigs to the Bootlin external
toolchain (glibc-stable), I figured out that the ARM64 CPUs in 32-bits
have no Bootlin toolchain available because of a lack for the likewise
'conditions': BR2_ARM_CPU_ARMV7A || BR2_ARM_CPU_ARMV8A
I am a little bit concerned about the change propose in this patch as
the 'conditions' could be used to generate the test if no 'test_options'
is defined, and that cannot split the following 'conditions' into single
option pieces:
(BR2_ARM_CPU_ARMV7A && BR2_ARM_EABIHF) || BR2_ARM_CPU_ARMV8A
This is the part of code that would not work if 'test_options' is unset:
if 'test_options' in arches[self.arch]:
test_options = arches[self.arch]['test_options']
else:
test_options = arches[self.arch]['conditions']
for opt in test_options:
if opt.startswith("!"):
f.write(" # %s is not set\n" % opt[1:])
else:
f.write(" %s=y\n" % opt)
However, this kind of "complex" 'conditions' with such CPU feature
options requires to get overriden by the 'test_options', right?
Regards,
Gaël PORTAY

I understand your concern, but I believe you're right that those
complex cases simply _must_ have test_conditions defined. I thought a
bit about this, and didn't see a reasonably simple solution other than
what you have proposed.
Thanks!
