2013-12-20Create local C library implementation (1/2)Harry Liebel
- This change is split into two separate patches in order to simplify the history as interpreted by 'git'. The split is between the move/rename and addition of new files. - Remove dependency on toolchain C library headers and functions in order to ensure behavioural compatibility between toolchains. - Use FreeBSD as reference for C library implementation. - Do not let GCC use default library include paths. - Remove unused definitions in modified headers and implementations. - Move C library files to 'lib/stdlib' and 'include/stdlib'. - Break std.c functions out into separate files.

2013-12-12Remove useless copies of meminfo structuresSandrine Bailleux
Platform setup code has to reserve some memory for storing the memory layout information. It is populated in early platform setup code. blx_get_sec_mem_layout() functions used to return a copy of this structure. This patch modifies blx_get_sec_mem_layout() functions so that they now directly return a pointer to their memory layout structure. It ensures that the memory layout returned by blx_get_sec_mem_layout() is always up-to-date and also avoids a useless copy of the meminfo structure. Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout() to make it clear those functions are platform specific. Change-Id: Ic7a6f9d6b6236b14865ab48a9f5eff545ce56551

2013-12-05Properly initialise the C runtime environmentSandrine Bailleux
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
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.

2013-11-27Move generic architectural setup out of blx_plat_arch_setup().Sandrine Bailleux
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
