2014-05-22Add support for BL3-1 as a reset vectorVikram Kanigiri
This change adds optional reset vector support to BL3-1 which means BL3-1 entry point can detect cold/warm boot, initialise primary cpu, set up cci and mail box. When using BL3-1 as a reset vector it is assumed that the BL3-1 platform code can determine the location of the BL3-2 images, or load them as there are no parameters that can be passed to BL3-1 at reset. It also fixes the incorrect initialisation of mailbox registers on the FVP platform This feature can be enabled by building the code with make variable RESET_TO_BL31 set as 1 Fixes ARM-software/TF-issues#133 Fixes ARM-software/TF-issues#20 Change-Id: I4e23939b1c518614b899f549f1e8d412538ee570
2014-05-07Access system registers directly in assemblerAndrew Thoelke
Instead of using the system register helper functions to read or write system registers, assembler coded functions should use MRS/MSR instructions. This results in faster and more compact code. This change replaces all usage of the helper functions with direct register accesses. Change-Id: I791d5f11f257010bb3e6a72c6c5ab8779f1982b3
2014-05-06Reduce deep nesting of header filesDan Handley
Reduce the number of header files included from other header files as much as possible without splitting the files. Use forward declarations where possible. This allows removal of some unnecessary "#ifndef __ASSEMBLY__" statements. Also, review the .c and .S files for which header files really need including and reorder the #include statements alphabetically. Fixes ARM-software/tf-issues#31 Change-Id: Iec92fb976334c77453e010b60bcf56f3be72bd3e
2014-05-06Refactor GIC header filesDan Handley
Move the function prototypes from gic.h into either gic_v2.h or gic_v3.h as appropriate. Update the source files to include the correct headers. Change-Id: I368cfda175cdcbd3a68f46e2332738ec49048e19
2014-05-06Move FVP power driver to FVP platformDan Handley
Move the FVP power driver to a directory under the FVP platform port as this is not a generically usable driver. Change-Id: Ibc78bd88752eb3e3964336741488349ac345f4f0
2014-04-16Remove redundant code from bl1_plat_helpers.SDan Handley
Remove redundant code in plat_secondary_cold_boot_setup() in plat/fvp/aarch64/bl1_plat_helpers.S. Fixes ARM-software/tf-issues#136 Change-Id: I98c0a46d95cfea33125e34e609c83dc2c97cd86e
2014-03-26Place assembler functions in separate sectionsAndrew Thoelke
This extends the --gc-sections behaviour to the many assembler support functions in the firmware images by placing each function into its own code section. This is achieved by creating a 'func' macro used to declare each function label. Fixes ARM-software/tf-issues#80 Change-Id: I301937b630add292d2dec6d2561a7fcfa6fec690
2014-03-10Remove unused 'CPU present' flagJeenu Viswambharan
This patch removes the 'CPU present' flag that's being set but not referred or used anywhere else. Change-Id: Iaf82bdb354134e0b33af16c7ba88eb2259b2682a
2014-01-17Change comments in assembler files to help ctagsJeenu Viswambharan
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

- Add instructions for contributing to ARM Trusted Firmware. - Update copyright text in all files to acknowledge contributors. Change-Id: I9311aac81b00c6c167d2f8c889aea403b84450e5
2013-12-05Various improvements/cleanups on the linker scriptsSandrine Bailleux
- 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.

2013-11-14Do not enable CCI on Foundation FVPHarry Liebel
- The Foundation FVP only has one cluster and does not have CCI. Change-Id: If91e81ff72c52e448150089c4cfea3e4d6ae1232
