* MIPS: provide a default u-boot-spl.ldsDaniel Schwierzeck2016-05-31-2/+3
| | | | | | | | | | | | Provide a default linker script for SPL binaries. Start address and size of text section and BSS section are configurable. All sections are arranged in a way that only relevant sections are kept in the code section for maximum size reduction. All other sections are kept but moved outside the code section to help with debugging. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com> Acked-by: Marek Vasut <marex@denx.de>
* MIPS: Kconfig: optimize gcc -march and -mtune setupDaniel Schwierzeck2016-01-16-6/+0
| | | | | | | | Move setup of -march to arch/mips/Makefile and follow the design on ARM. Also add a possibility to chose specific CPU tune options. Signed-off-by: Wills Wang <wills.wang@live.com> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
* MIPS: add initial infrastructure for device-tree filesDaniel Schwierzeck2016-01-16-0/+1

* MIPS: do not build position-independent executables for SPLDaniel Schwierzeck2016-01-16-4/+14
| | | | | | | | | SPL binaries are usually linked to a fixed address in SRAM. Furthermore SPL binaries do not need to relocate itself. Thus do not build them as position-independent binaries which helps to largely reduce the size of SPL binaries. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* MIPS: add .padding section to linker scriptDaniel Schwierzeck2014-11-01-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Commit 79fd7e649e287228a1445820a72f7dd33baedb96 MIPS: always keep all sections in u-boot ELF binary. Always keep all sections in u-boot ELF binary. Move all unneeded sections after _end to avoid allocating space in the final binary. Also remove .deadcode section which is now obsolete. removed section .deadcode because the original symptoms were not visible anymore. Unfortuneatly the binutils bug still exists. The size of .rel.dyn section is often bigger than needed for all entries. But objcopy only allocates space as much as required for all reloc entries. Thus there is a gap between the last entry and __rel_dyn_end in u-boot.bin. If u-boot is booted from RAM (e.g. in SPL scenarios) that area could contain garbage data which could lead to CPU exceptions during relocation.

* kbuild: fix CROSS_COMPILE settings in config.mkMasahiro Yamada2014-03-04-1/+3
| | | | | | | | | | | | | | | | The syntax CROSS_COMIPLE ?= <cross_compiler_prefix> does not work because config.mk is parsed after exporting CROSS_COMPILE. Like Linux Kernel's arch/$(ARCH)/Makefile, we must write as follows: ifeq ($(CROSS_COMPILE),) CROSS_COMPILE := <cross_compiler_prefix> endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

* MIPS: add dynamic relocation supportGabor Juhos2013-02-12-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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 <juhosg@openwrt.org> Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
