This patch performs the following:
- Creating two corstone700 platforms under corstone700 board:
fvp and fpga
- Since the FVP and FPGA have IP differences, this commit provides a specific DTS for each platform
- The platform can be specified using the TARGET_PLATFORM Makefile variable
(possible values are: fvp or fpga)
- Allowing to use u-boot by:
- Enabling NEED_BL33 option
- Fixing non-secure image base: For no preloaded bl33 we want to
have the NS base set on shared ram. Setup a memory map region
for NS in shared map and set the bl33 address in the area.
- Setting the SYS_COUNTER_FREQ_IN_TICKS based on the selected
platform
- Setting ARM_MAP_SHARED_RAM and ARM_MAP_NS_SHARED_RAM to use MT_MEMORY
