[dpdk-dev] Correct use of Arm related names

[Honnappa Nagarahalli]

Hi,
This email was triggered by a request to change ARM to Arm in the dpdk.org webpage. I went down the path of finding out the correct names to use. There has not been consistency in using these names across all other projects. So, the recommendation I have got is, 'choose something and use it consistently' (within the DPDK project). Following are my recommendations (please notice the lower/upper case of the letters):

Architectural State:
aarch64/arm64 - referring to aarch64 state - recommended: aarch64
aarch32/arm32 - referring to aarch32 state - recommended: aarch32 (arm32 might create confusion with armv7)

ISA:
armv8.x
armv7.x

Any reference to Company name:
Arm

So, everything is lower case except when referring to the company (for ex: Copyright) name.

Please let me know if you have any questions.

Thank you,
Honnappa

There is still confusion about when to use the arch name (aarch64)
or the ISA (armv8)?

For instance, the lib/librte_eal/common/include/arch/arm/ directory
has files split by 32/64 arch. I thought it would make more sense to have
different low-level routines depending of the ISA.

Is it possible to have armv7 in aarch64?
Is it possible to have armv8 in aarch32?
