[U-Boot] [PATCH] arm:ls1021a: Reserve secure code into RAM instead of OCRAM

[Zhang Z.Y.]

Hi, York

Sorry for the delay, I wrongly filter this patch and missed it.
As for your question, if platform does not define CONFIG_ARMV7_SECURE_BASE, U-boot  will help define a default secure text section in linker script to reserve secure code. CONFIG_ARMV7_SECURE_BASE  for LS1 is previously defined as OCRAM_BASE, This patch just remove it and use DDR by default.
