Re: [U-Boot] Whose responsibility is it to enable FPU?

Dear gnemas@gmail.com,

In message 0016e6480e82187a72048902213a@google.com you wrote:

I built u-boot for a 440EPx board derived from the sequoia configuration.

U-Boot runs fine and successfully boots my operating system (Linux and uClibc-based root filesystem).

Then I realized that the FPU was not enabled in the MSR or in the ccr0 register.

Have I misconfigured something, or should I go ahead and add code to u-boot to enable the FPU?

U-Boot does not need nor use the FPU, so enabling it would not help you in any way.

Linux will do it's own settings, so this is where you need to look for your incorrect configuration settings (incorrect CPU description in the DT?).
