PLAT_SP_IMAGE_NS_BUF_BASE in arm_spm_def.h is located in
ARM_AP_TZC_DRAM1_BASE.
Because of this, to use PLAT_SP_IMAGE_NS_BUF_BASE in normal world,
the TZC region configuration is required like this:
0: ARM_AP_TZC_DRAM1_BASE to PLAT_SP_IMAGE_NS_BUF_BASE (secure only)
1: PLAT_SP_IMAGE_NS_BUF_BASE to PLAT_SP_IMAGE_NS_BUF_SIZE
(ns and secure)
2: PLAT_SP_IMAGE_NS_BASE + PLAT_SP_IMAGE_NS_BUF_SIZE to
ARM_AP_TZC_DRAM1_BASE + ARM_EL3_TZC_DRAM1_END (secure only)
To reduce TZC area for PLAT_SP_IMAGE_NS_BUF_BASE
Let add ARM_SPM_NS_MEM_BASE where located in
(ARM_AP_TZC_DRAM1_BASE) - 1MB as much as 1MB.
and locate PLAT_SP_IMAGE_NS_BUF in this area.
So that reduce the TZC region in ARM_TZC_REGIONS_DEF.
