The current build system and driver requires the CCI product to be specified at build time. The device constraints can be determined at run time from its ID registers, obviating the need for specifying them ahead. This patch adds changes to identify and validate CCI at run time. Some global variables are renamed to be in line with the rest of the code base. The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is updated.
