Does the barebox filetype detection need a fix aswell?
enum filetype file_detect_type(void *_buf)
{
u32 *buf = _buf;
u8 *buf8 = _buf;
if (strncmp(buf8, "#!/bin/sh", 9) == 0)
return filetype_sh;
if (buf[8] == 0x65726162 && buf[9] == 0x00786f62)
return filetype_arm_barebox;
This seems wrong on big endian systems.
