I had the same problem with an ancient version of a vendor-ported u-boot. There
my CFG_HZ was 100, so the timeout was 0.
I used this, which avoids the preprocessor conditional. Since the HZ value
is a compile-time constant, the compiler chooses the if or else branch and
doesn't
spit a run-time conditional.2
if (CFG_HZ > 100000)
tout *= CFG_HZ/1000; /* for a big HZ, avoid overflow */
else
tout = tout * CFG_HZ / 1000 + 1;
