[Buildroot] [PATCH 0/2] Add support for rpi3 64bits target

[Buildroot] [PATCH 0/2] Add support for rpi3 64bits target

[Gaël PORTAY]

Hi,

Those two patches bring the support for a 64bits image of the RaspberryPi 3.

The first patch makes the rpi-firmware package to be available for aarch64
targets (so it can be used by the second patch).

The second patch adds a minimal defconfig to build a 64bits rpi3 image.

 Isn't it better to just make a new raspberrypi3-64 symlink?

 I think an explicit BR2_cortex_a53=y should be added. It's the default because
it's the first one in the list, but I don't think it's good to rely on that.

 BTW, does anyone know why the 32-bit version has cortex_a7?

 I'd prefer a little bit more slack, I used 120000 in the defconfigs I just
updated. And if that is not enough (or very tight), just jump directly to 250000.

I am sorry, could you detail a bit more... I did not get it :/

Indeed, it was present in my first draft. I did savedefconfig and cleaned it
up, and make it disappeared :(

I think I was the magic a copy/paste. I have a patch to update the 32bit version
to cortex_a53, but it breaks compilation of qt5base.

I am still working on it. I located the bug but I don't know yet how to fix it
(properly).

To sum-up, setting BR2_cortex_a53 builds an armv8 toolchain that outputs 32bits
binaries.

Here are the ARM defines.

	#define __arm__ 1
	#define __ARM_32BIT_STATE 1
	#define __ARM_ARCH 8
	#define __ARM_ARCH_8A__ 1
	#define __ARM_ARCH_EXT_IDIV__ 1
	#define __ARM_ARCH_ISA_ARM 1
	#define __ARM_ARCH_ISA_THUMB 2
	#define __ARM_ARCH_PROFILE 65
	#define __ARM_EABI__ 1
	#define __ARMEL__ 1
	#define __ARM_FEATURE_CLZ 1
	#define __ARM_FEATURE_CRC32 1
	#define __ARM_FEATURE_DSP 1
	#define __ARM_FEATURE_IDIV 1
	#define __ARM_FEATURE_LDREX 15
	#define __ARM_FEATURE_QBIT 1
	#define __ARM_FEATURE_SAT 1
	#define __ARM_FEATURE_SIMD32 1
	#define __ARM_FEATURE_UNALIGNED 1
	#define __ARM_PCS 1
	#define __ARM_SIZEOF_MINIMAL_ENUM 4
	#define __ARM_SIZEOF_WCHAR_T 4

The flag __ARM_FEATURE_CRC32 is now defined and qtbase uses the AArch32/AArch64
CRC instructions to build an hardware accelerated implementation of its crc32
function [1].

	tools/qhash.cpp:148:54: error: attribute(target("+crc")) is unknown
	 static uint crc32(const Char *ptr, size_t len, uint h)

+crc is an ARMv8 only attribute [2]. __ARM_FEATURE_CRC32 is set for both AArch32
and AArch64 [3].

	6.5.8 CRC32 Extension
	__ARM_FEATURE_CRC32 is defined to 1 if the CRC32 instructions are
	supported and the intrinsics defined in 9.7 are available. These
	instructions include CRC32B, CRC32H etc. This is only available when
	__ARM_ARCH >= 8

	9.7 CRC32 intrinsics
	CRC32 intrinsics provide direct access to CRC32 instructions
	CRC32{C}{B, H, W, X} in both ARMv8 AArch32 and AArch64 execution states.
	These intrinsics are available when __ARM_FEATURE_CRC32 is defined.

The quick fix I found is to check for both define __aarch64__ and
__ARM_FEATURE_CRC32 instead of checking the single define __ARM_FEATURE_CRC32.

	#if defined(__aarch64__) && defined(__ARM_FEATURE_CRC32)

If anyone knows on which flag I can rely on... I can open a dedicated thread
about this bug.

I think because back when the rpi3 defconfig was added, there was no
selection of AArch64 cores.
