RE: [DPDK][PATCH v4] config/arm: add Ampere AmpereOneAC04 platform

[Yutang Jiang <yutang.jiang@amperecomputing.com>]

Due to changes in product family naming conventions, this updated version has no other changes except for some string adjustments.

Hi Thomas,
According to your suggestion, this version has also added a small description of the platform.


Best Regards,
Yutang Jiang
