Change stub example to use asm-generic/sections.h

2013-03-15T20:13:58Z

We can use the declarations of __bss_start and _end from this header instead of declaring them locally. Signed-off-by: Simon Glass

Introduce generic link section.h symbol files

2013-03-15T20:13:58Z

We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini (version 5) Signed-off-by: Simon Glass

MIPS: add dynamic relocation support

2013-02-12T21:22:13Z

The code handles relocation entries with the following relocation types only: mips32: R_MIPS_REL32 mips64: R_MIPS_REL+R_MIPS_64 xburst: R_MIPS_REL32 Other relocation entries are skipped without processing. The code must be extended if other relocation types must be supported. Add -pie to LDFLAGS_FINAL to generate the .rel.dyn fixup table, which will be applied to the relocated image before transferring control to it. The CONFIG_NEEDS_MANUAL_RELOC is not needed after the patch, so remove that as well. Signed-off-by: Gabor Juhos Signed-off-by: Daniel Schwierzeck

MIPS: start.S: use symbol __image_copy_end for U-Boot image relocation

2013-02-12T21:22:13Z

Use the newly introduced symbol __image_copy_end as end address for relocation of U-Boot image. This is needed for dynamic relocation added in later patches. This patch obsoletes the symbols uboot_end and uboot_end_data which are removed. Signed-off-by: Daniel Schwierzeck

MIPS: u-boot.lds: introduce symbol __image_copy_end

2013-02-12T21:22:12Z

This symbol is used in later patches as end address for relocation of the U-Boot image into RAM. Signed-off-by: Daniel Schwierzeck

MIPS: u-boot.lds: merge all BSS sections and introduce symbols __bss_[start|end]

2013-02-12T21:22:12Z

These symbols are used in later patches for as addresses for clearing the BSS area in the relocated U-Boot image. Signed-off-by: Daniel Schwierzeck

MIPS: xburst: fix broken access to global_data

2013-02-12T21:22:12Z

Fix access to global_data which is broken since commits: commit 035cbe99cd2fd4adf9d7fd95aeebb5f814e37eb9 Author: Simon Glass Date: Thu Dec 13 20:49:08 2012 +0000 mips: Move per_clk and dev_clk to arch_global_data Move these field into arch_global_data and tidy up. The other CONFIG_JZSOC fields are used by various architectures, so just remove the #ifdef bracketing for these.

Add architecture-specific global data

2013-02-01T20:07:49Z

We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain. Signed-off-by: Simon Glass
