Yatharth Kochar 79a97b2ef7 Call reset handlers upon BL3-1 entry. ... This patch adds support to call the reset_handler() function in BL3-1 in the cold and warm boot paths when another Boot ROM reset_handler() has already run. This means the BL1 and BL3-1 versions of the CPU and platform specific reset handlers may execute different code to each other. This enables a developer to perform additional actions or undo actions already performed during the first call of the reset handlers e.g. apply additional errata workarounds. Typically, the reset handler will be first called from the BL1 Boot ROM. Any additional functionality can be added to the reset handler when it is called from BL3-1 resident in RW memory. The constant FIRST_RESET_HANDLER_CALL is used to identify whether this is the first version of the reset handler code to be executed or an overridden version of the code. The Cortex-A57 errata workarounds are applied only if they have not already been applied.
