- Check at link-time that bootloader images will fit in memory at run time and that they won't overlap each other. - Remove text and rodata orphan sections. - Define new linker symbols to remove the need for platform setup code to know the order of sections. - Reduce the size of the raw binary images by cutting some sections out of the disk image and allocating them at load time, whenever possible. - Rework alignment constraints on sections. - Remove unused linker symbols. - Homogenize linker symbols names across all BLs. - Add some comments in the linker scripts.

A single binary can be compiled using a command such as: make CROSS_COMPILE=aarch64-none-elf- bl1 Also make use of brackets consistent in the Makefile. Change-Id: I2180fdb473411ef7cffe39670a7b2de82def812e

- Large RAM-disks may have trouble starting with 2GB of memory. - Increase from 2GB to 4GB in FDT. Change-Id: I12c1b8e5db41114b88c69c48621cb21247a6a6a7

On FVP platforms, for now it is assumed that the normal-world bootloader is already sitting in its final memory location. Therefore, BL2 doesn't need to load it and so it doesn't need to know the extents of the non-trusted DRAM. Change-Id: I33177ab43ca242edc8958f2fa8d994e7cf3e0843

Also, don't invalidate the TLBs in disable_mmu() function, it's better to do it in enable_mmu() function just before actually enabling the MMU. Change-Id: Ib32d6660019b0b2c17254156aad4be67ab4970e1

Any asynchronous exception caused by the firmware should be handled in the firmware itself. For this reason, unmask SError exceptions (and Debug ones as well) on all boot paths. Also route external abort and SError interrupts to EL3, otherwise they will target EL1. Change-Id: I9c191d2d0dcfef85f265641c8460dfbb4d112092

Global and static variables are expected to be initialised to zero by default. This is specified by the C99 standard. This patch removes some unnecessary initialisations of such variables. It fixes a compilation warning at the same time: plat/fvp/bl31_plat_setup.c:82:3: warning: missing braces around initializer [-Wmissing-braces] section("tzfw_coherent_mem"))) = {0}; ^ plat/fvp/bl31_plat_setup.c:82:3: warning: (near initialization for ‘ns_entry_info[0]’) [-Wmissing-braces] Note that GCC should not have emitted this warning message in the first place. The C Standard permits braces to be elided around subaggregate initializers. See this GCC bug report: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53119 Change-Id: I13cb0c344feb9803bca8819f976377741fa6bc35

blx_plat_arch_setup() should only perform platform-specific architectural setup, e.g. enabling the MMU. This patch moves generic architectural setup code out of blx_plat_arch_setup(). Change-Id: I4ccf56b8c4a2fa84909817779a2d97a14aaafab6

- The Foundation FVP is a cut down version of the Base FVP and as such lacks some components. - Three FDTs are provided. fvp-foundation-gicv2legacy-psci: Use this when setting the Foundation FVP to use GICv2. In this mode the GIC is located at the VE location, as described in the VE platform memory map. fvp-foundation-gicv3-psci : Use this when setting the Foundation FVP to use GICv3. In this mode the GIC is located at the Base location, as described in the Base platform memory map. fvp-foundation-gicv2-psci : Use this when setting the Foundation FVP to use GICv3, but Linux is expected to use GICv2 emulation mode. In this mode the GIC is located at the Base location, but the GICv3 is used in GICv2 emulation mode. Change-Id: I9d69bcef35c64cc8f16550efe077f578e55aaae5
