Check was incorrectly being applied to size of elf phdrs, instead
of the number. The ELF standard allows for up to 65535 headers, but
the check was being compared to the number of headers multiplied by
the size of a program header.

Hello Tao,
Let me more clear. When you set (3, 15, 14) the device sometimes
response nack.
but when you set (4, 7, 7), the device always ack. Am I right?

Jagan,
The compatible is for the real hardware name as Maxime previously explained.
The platform is described in the latter part.
Please use:
compatible = "oceanic,5205-5inmfd", "allwinner,sun50i-a64";
Thanks,

uot;, "allwinner,sun50i-a64";
Perhaps this solves the issue. Please let me know thoughts.
