[U-Boot] [PATCH v2 16/19] arm: socfpga: Enhance Intel SoCFPGA program header to support Arria 10

[tien.fong.chee at intel.com]

From: Tien Fong Chee <tien.fong.chee at intel.com>

Enhance preloader header with both additional program length and program
entry offset attributes, which offset is relative to the start of program
header.
