Thanks Sughosh. Can you build an U-Boot with the following defined
in the hawkboard.h config file?

#define DEBUG
#if defined(CONFIG_SPL_BUILD) && ! defined (__ASSEMBLY__)
static inline int printf(const char *fmt, ...)
{
        return 0;
}
#endif

Note: only the #define DEBUG matter to me, but with it alone, SPL build
fails due to some code now requiring printf(). This is why I add a
dummy printf definition for C code during SPL build -- ASM code does not
need printf() and actually chokes on the definition, hence the
condition on __ASSEMBLY__.

This debug U-Boot should print a lot more info. Can you please try it
and copy/paste its output here? Thanks in advance.

Amicalement,
