Commit Message

Add a new target named "qoriq", that will support boards using PowerPC
processors from NXP's QorIQ brand.

This doesn't actually add support for any board yet, so that
installation instructions can go in the commit message of the commit
that adds actual support for a board.

Hi, Stijn,

Nice to see this! :) A few nits/comments/questions below…

Should we keep TESTING_PATCHVER when it's the same version?

We shouldn't need 32-bit time_t compatibility, since we're building
from scratch.

I see a Qoriq-specific cpufreq driver selected (down below), but we're
defaulting to performance here. Is frequency scaling actually working,
or is it disabled for performance/latency reasons?

Do we need both ladder and TEO? TEO should be the best option, nowadays.

This is confusing. Isn't the CPU an e5500? I haven't looked at the
kconfig, so I'm not sure how this appears when make(ing)
kernel_menuconfig.

Do we have tickless idle? If so, it should be enabled (instead of
periodic ticks), in order to save power, unless there's a specific
reason to disable it.

The e5500 should implement a complete IEEE 754 compliant FPU,
according to the datasheet. I don't see a reason to enable any math
emulation.

[snipped the rest, as it looks sane]

On the e6500 (M300), it is not usable due to erratum A-008083. The e5500
(M200, BSAP-3040) does not have this problem so I prefer to leave it
enabled. Enabled all governors and selected schedutil as the default,
analog to several other targets.

Side effect of not having enabled tickless idle, fixed.

The M300 is an e6500. I've downgraded CPU_TYPE to e5500 to be able to
support both e5500 and e6500 in the generic subtarget to avoid having
different subtargets. Now for the kernel part, selecting E5500_CPU will
result in -mcpu=powerpc64 rather than -mcpu=e5500. As the only
difference is the presence of AltiVec or not, and the kernel does
runtime detection anyway, I'd prefer to keep E6500 here. For musl,
runtime detection will be enabled only when AltiVec support is not
defined at compile time, so using e5500 for CPU_TYPE will result in an
unneeded runtime check on E6500, but we need that for the E5500 based
models that will be supported in the future.

Good catch. Enabled tickless idle.

It does not implement fsqrt nor fsqrts. As musl hardcodes sqrt and sqrtf
to use these ASM instructions, this is required to avoid SIGILL.
