AST2600 ARM CPU - 64 byte PCIe MemRd and MemWr

[sainath grandhi]

Hello,
I am reaching out to check if someone knows how (or if someone tried) to
generate a 64 byte MemRd or MemWr PCIe TLP on an AST2600.
AST2600 uses Dual-core ARM Cortex A7 processor.

Quick search on internet says that X86 supports Memory Write combining
feature to be able to generate a 64 byte PCIe TLP. But there is not much
information about similar support for ARM CPUs.

Thanks
