RE: Fwd: build u-boot failed with config CONFIG_ARMV8_PSCI by aarch linux gcc 8.1

[Li, Meng]

Hi Renlin,

 

Thanks for your advice.

As you said, I tried to modify u-boot, and then building passed.

 

Thanks,

Limeng

Hi Meng,

 

Thanks for raising the issue!

I could reproduce the issue with the information you gave.

 

It seems to me that, the change I made earlier catches an issue here.

in /arch/arm/cpu/armv8/psci.S

 

/* PSCI function and ID table definition*/

#define PSCI_TABLE(__id, __fn) \

          .word __id; \

          .word __fn

 

".word" is used to hold the address of a function.

 

The toolchain you used is aarch64-linux, which by default supports LP64 ABI.

This means Long and void * (pointer) data type is 64-bit.

 

IIUC, a ".xword" should be used instead. Otherwise, you should use ILP32 ABI. But be aware, the support for ILP32 might not be complete.

 

Regards,

Renlin

 

 

Hi All,
Could you please help to have a look whether below issue is valuable?
I got u-boot source code from https://github.com/u-boot/u-boot.git, branch =
is master.
I got toolchain from https://mirrors.edge.kernel.org/pub/tools/crosstool/fi=
les/bin/x86_64/8.1.0/
I built stratix10(socfpga) platform with below commands:
export CROSS_COMPILE=3Dxxx/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux=
-
export ARCH=3Darm64
make mrproper
make socfpga_stratix10_defconfig
make menuconfig, and then enable CONFIG_ARMV8_PSCI
make
there will be below error:
