Subject: ddr: altera: stratix10: Move SDRAM size check to SDRAM driver
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b6f7ee5d1f980ffa63e22749e2deae6caa57227e;p=project%2Fbcm63xx%2Fu-boot.git

ddr: altera: stratix10: Move SDRAM size check to SDRAM driver

Move SDRAM size check to SDRAM driver. sdram_calculate_size()
is called in SDRAM initialization already, avoid calling
twice in size check function.
