arm: Add support of updating dts before fix-up

2017-12-24T19:42:50Z

"ethernet" node fix-up for device tree happens before Linux boot. There can be requirement of updating "ethernet" node even before fix-up. So, add support of updating "ethernet" node. Signed-off-by: Prabhakar Kushwaha Reviewed-by: York Sun

efi_loader: helloworld.c: Reduce file size

2017-12-16T21:51:19Z

The efi linker script includes sections needed for the dynamic linker. However, in our EFI application environment we don't have a dynamic linker. So let's remove them. That way we save on 4k padding and reduce the file size of the hello world efi binary from ~4k to ~1k. Signed-off-by: Alexander Graf

arm64 :show_regs: show the address before relocation

2017-12-04T15:23:52Z

After relocation, when error happends, it is hard to track ELR and LR with asm file objdumped from elf file. So subtract the gd->reloc_off the reflect the compliation address. Signed-off-by: Peng Fan Reviewed-by: Simon Glass

arm: provide a PCS-compliant setjmp implementation

2017-11-21T22:57:22Z

The previous setjmp-implementation (as a static inline function that contained an 'asm volatile' sequence) was extremely fragile: (some versions of) GCC optimised the set of registers. One critical example was the removal of 'r9' from the clobber list, if -ffixed-reg9 was supplied. To increase robustness and ensure PCS-compliant behaviour, the setjmp and longjmp implementation are now in assembly and closely match what one would expect to find in a libc implementation.

arm: boot0 hook: move boot0 hook before '_start'

2017-11-21T22:57:21Z

The boot0 hook on ARM does not insert its payload before the vector table. This is both a mismatch with thec comment above it and contradict usage of the boot0 hook on ARM64. To fix this (and unify the semantics for ARM and ARM64), we change the boot0-hook semantics on ARM to match those on ARM64: (1) if a boot0-hook is present it is inserted at the start of the image (2) if a boot0-hook is present, emitting the ARM vector table (and the _start) symbol are suppressed in vectors.S and the boot0-hook has full control over where and when it wants to emit these Signed-off-by: Philipp Tomsich

arm64: support running at addr other than linked to

2017-11-17T12:44:13Z

This is required in the case where U-Boot is typically loaded and run at a particular address, but for some reason the RAM at that location is not available, e.g. due to memory fragmentation loading other boot binaries or firmware, splitting an SMP complex between various different OSs without using e.g. the EL2 second-stage page tables to hide the memory asignments, or due to known ECC failures.
