From 68a68c925f6d2b9266b53fb6257b58ff720c3bcd Mon Sep 17 00:00:00 2001 From: Sandrine Bailleux Date: Mon, 28 Sep 2015 17:03:06 +0100 Subject: Introduce print_entry_point_info() function This patch introduces a new function called 'print_entry_point_info' that prints an entry_point_t structure for debugging purposes. As such, it can be used to display the entry point address, SPSR and arguments passed from a firmware image to the next one. This function is now called in the following images transitions: - BL1 to BL2 - BL1 to BL31 - BL31 to the next image (typically BL32 or BL33) The following changes have been introduced: - Fix the output format of the SPSR value : SPSR is a 32-bit value, not a 64-bit one. - Print all arguments values. The entry_point_info_t structure allows to pass up to 8 arguments. In most cases, only the first 2 arguments were printed. print_entry_point_info() now prints all of them as 'VERBOSE' traces.
