Phytium released 3 series of CPU including TengYun S - server,
TengRui D - desktop and TengLong E - embedded. please refer to the introduction link:
https://www.phytium.com.cn/en/class/11

so it would be better if you change config/arm/arm64_fts2500_linux_gcc  to
config/arm/arm64_tys2500_linux_gcc

tys2500 looks better.

Phytium TengYun S2500 server series have 2P_128core, 4P_256core
and up to 8P_512core SKUs. Single processor of them is ARMv8-a
architecture with part number 0x663, 8 NUMA nodes, 64 cores.

you may add Phytium TengYun S2500 servers with the
max configuration 4P_256core_32NUMA, and ignore 8P_512core_64NUMA
since this SKU has not been found in current market, can't be tested.
