[yocto] [meta-raspberrypi][PATCH 1/1] Modify raspberrypi3.conf and add raspberrypi3-64.conf

[Herve Jourdain]

Hi Khem,

For cortexa53 in aarch32, the problem is to figure out if we want to cover all cases or not.
Raspberrypi3 is one case of CortexA53 that has crc support, but no crypto support. So I could define a cortexa53-32 as being just that.
But then, there are other CortexA53-based SoCs that do have the crypto extension, and I thought that, since I was going to modify it, I'd rather cover all possible cases/options...

The one thing that could be scrapped is the hf option, if we decide that all cortexa53 aarch32 will be hf only.
Then that would avoid the hf duplication of the aarch32 tunes, leaving only 2 tunes for cortexa53 aarch32 + 1 tune for cortexa53 aarch64.

Please advise what you would prefer me to do.

Herve

Herve,

There is no need to create so many variants for a53 32 bit mode. We can keep using whatever we have its only 64bit that needs to be added as a new machine.
