The boot parameters are read from individual variables assigned for each of them. This been corrected and now they are stored as a part of the global data 'gd' structure. So read them from 'gd' instead. Signed-off-by: Sricharan R <r.sricharan@ti.com> [trini: Add igep0033 hunk] Signed-off-by: Tom Rini <trini@ti.com>
