* Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

| * microblaze: Add muldi3.c which contains routines for _muldi3David Holsgrove2013-02-04-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Referenced arch/blackfin/lib/muldi3.c and the linux kernel. Resolves issue seen when building u-boot for HW_MUL=0; PLATFORM_CPPFLAGS += -mxl-soft-mul PLATFORM_CPPFLAGS += -mno-xl-multiply-high which resulted in error while linking to libgcc.a without mul hw (bs / m); libgcc.a(_muldi3.o): In function `__muldi3': .... src/gcc-4.6.2/libgcc/libgcc2.c:550: undefined reference to `_GLOBAL_OFFSET_TABLE_' This link failure would not occur if we used gcc instead of ld directly, as gcc will correctly use the crt's to resolve this link.

* | Add architecture-specific global dataSimon Glass2013-02-01-0/+6
|/ | | | | | | | | | | | | 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.

* microblaze: Fix compilation failure because of missing libdtsMichal Simek2012-11-08-0/+2
| | | | | | | | | | Microblaze platform can use CONFIG_OF_EMBED option but also it is necessary to support boards which don't want to use this option. U-Boot doesn't compile dts/libdts.o for #undef CONFIG_OF_EMBED case that's why it should be guarded by ifdef. Signed-off-by: Michal Simek <monstr@monstr.eu>
