arm: implement ELF relocations ELF relocation tables generated with linker option -pie can be used to fixup code and data in a single loop at relocation, removing the need for manual fixups anywhere else in the code. Signed-off-by: Albert Aribaud <albert.aribaud@free.fr>

ARM: add relocation support !! This breaks support for all arm boards !! To compile in old style, you must define CONFIG_SYS_ARM_WITHOUT_RELOC or you can compile with "CONFIG_SYS_ARM_WITHOUT_RELOC=1 ./MAKEALL board" !! This define will be removed soon, so convert your board to use relocation support Portions of this work were supported by funding from the CE Linux Forum.

arm: Move CP15 init out of cpu_init_crit() Some SOCs have do not start up with their 'main' CPU. The first U-Boot code may then be executed with a CPU which does not have a CP15, or not a useful one. Here we split the initialization of CP15 into a separate call, which can be performed later if required. Once the main CPU is running, you should call cpu_init_cp15() to perform this init as early as possible. Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not need to change, this CP15 init is still skipped in that case. The only impact for these boards is that the cpu_init_cp15() will be available even if it is never used on these boards.

ls2080: Exit dpaa only right before exiting U-Boot On ls2080 we have a separate network fabric component which we need to shut down before we enter Linux (or any other OS). Along with that also comes configuration of the fabric using a description file. Today we always stop and configure the fabric in the boot script and (again) exit it on device tree generation. This works ok for the normal booti case, but with bootefi the payload we're running may still want to access the network. So let's add a new fsl_mc command that defers configuration and stopping the hardware to when we actually exit U-Boot, so that we can still use the fabric from an EFI payload. For existing boot scripts, nothing should change with this patch. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: York Sun <york.sun@nxp.com> [agraf: Fix x86 build]
