Replace all SCP FW (BL0, BL3-0) references
This patch replaces all references to the SCP Firmware (BL0, BL30,
BL3-0, bl30) with the image terminology detailed in the TF wiki
(https://github.com/ARM-software/arm-trusted-firmware/wiki):
BL0 --> SCP_BL1
BL30, BL3-0 --> SCP_BL2
bl30 --> scp_bl2
This change affects code, documentation, build system, tools and
platform ports that load SCP firmware. ARM plaforms have been
updated to the new porting API.
IMPORTANT: build option to specify the SCP FW image has changed:
BL30 --> SCP_BL2
IMPORTANT: This patch breaks compatibility for platforms that use BL2
to load SCP firmware. Affected platforms must be updated as follows:
BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
BL30_BASE --> SCP_BL2_BASE
bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo()
bl2_plat_handle_bl30() --> bl2_plat_handle_scp_bl2()
