If dram_init_banksize() is called from SPL, the rom_pointer, at that point, is not correctly initialized. This causes wrong calculation of DRAM start and size in dram_init_banksize(). The issue became apparent only in Falcon Mode. Added an extra condition to prevent using rom_pointer in SPL.

Signed-off-by: Elena Popa elena.popa@nxp.com --- V2: Added the extra condition also in dram_init() and get_effective_memsize() for consistency. --- arch/arm/mach-imx/imx8m/soc.c | 7 ++++--- arch/arm/mach-imx/imx9/soc.c | 6 +++--- 2 files changed, 7 insertions(+), 6 deletions(-)
