[PATCH 1/1] of: unittest: overlay: ensure proper alignment of copied FDT

2021-04-07 Thread frowand . list
From: Frank Rowand The Devicetree standard specifies an 8 byte alignment of the FDT. Code in libfdt expects this alignment for an FDT image in memory. kmemdup() returns 4 byte alignment on openrisc. Replace kmemdup() with kmalloc(), align pointer, memcpy() to get proper alignment. The 4 byte al
