Ctags seem to have a problem with generating tags for assembler symbols when a comment immediately follows an assembly label. This patch inserts a single space character between the label definition and the following comments to help ctags. The patch is generated by the command: git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1' Change-Id: If7a3c9d0f51207ea033cc8b8e1b34acaa0926475

Traps when accessing architectural features are disabled by clearing bits in CPTR_EL3 during early boot, including accesses to floating point registers. The value of this register was previously undetermined, causing unwanted traps to EL3. Future EL3 code (for example, context save/restore code) may use floating point registers, although they are not used by current code. Also, the '-mgeneral-regs-only' flag is enabled in the GCC settings to prevent generation of code that uses floating point registers. Change-Id: I9a03675f6387bbbee81a6f2c9ccf81150db03747

ns_entry_info used to be a per-cpu array. This is a waste of space because it is only accessed by the primary CPU on the cold boot path. This patch reduces ns_entry_info to a single-cpu area. Change-Id: I647c70c4e76069560f1aaad37a1d5910f56fba4c

The runtime exception handling assembler code used magic numbers for saving and restoring the general purpose register context on stack memory. The memory is interpreted as a 'gp_regs' structure and the magic numbers are offsets to members of this structure. This patch replaces the magic number offsets with constants. It also adds compile time assertions to prevent an incorrect assembler view of this structure. Change-Id: Ibf125bfdd62ba3a33e58c5f1d71f8c229720781c

This patch makes sure the C runtime environment is properly initialised before executing any C code. - Zero-initialise NOBITS sections (e.g. the bss section). - Relocate BL1 data from ROM to RAM. Change-Id: I0da81b417b2f0d1f7ef667cc5131b1e47e22571f

- 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.

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

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
