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.

For ls1021a, Reserve secure code in to memory in case OCRAM is needed by other usage.

Zhuoyu,
I don't see how the secure code is reserved in RAM. You only remove CONFIG_ARMV7_SECURE_BASE. Did I miss something?
