So far the i.MX BL31 doesn't take any parameters. This means the BL32 image base address and whether or not a BL32 image is used at all has to be hardcoded in BL31. This adds a helper function that allows to take params from BL2 safely. On i.MX BL2 is usually U-Boot SPL which passes random values in arg0, so make sure arg0 is within the internal SRAM range before accessing it as a pointer. Also make sure arg0 is sufficiently aligned and the header type and version is correct. Change-Id: Idab8013a1d6dabf50a83c75f3e6f831de4a537e9 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
