Fix: misconfig FPU in sys_clock_init

[louisom]

When testing stm32f429i on qemu-gnueclipse, it bump out
"qemu-system-gnuarmeclipse: Attempt to set CP10/11 in SCB->CPACR, but FP is not supported yet."

Found in sys_clock_init only check STM32F4X, then enable FPU and floating point
state preservation.

Adding CONFIG_FPU to prevent misconfig of FPU.

Hi everyone!
I have experimented such error emulating a discovery board based on a M4F with QEMU (version win64-2.7.0-201611282115).
Could you help me about where "adding CONFIG_FPU to prevent misconfig of FPU."?

Thanks in advance,

Eduardo

Eduardo, can you re-configure F9 microkernel with FPU enable? Did you encounter any building issues?

Hi Jim,
I missed comment you that I using QEMU as a Eclipse plugin on STM32CubeIDE for educational purposes.
By searching in the web, the (almost) only reference regarding FPU error on QEMU I found was your thread.
I haven´t work with F9 Microkernel.
I have all my projects based in those tools, and at present because of pandemy issues Im´trying to run some projects in a virtual way using QEMU.

Regards,

Eduardo
