Leif Lindholm 43d4231432 configure.ac: clean up arm64 soft-float handling
Fix compilation with gcc 5.1 (avoid internal compiler error), by
replacing explicit -march +nofp+nosimd options with -mgeneral-regs-only.

This also enables the removal of some further conditional build flag
setting.

Leif Lindholm d47e8ab4b9 dl_helper: Cleanup
Use the new thumb_get_instruction_word/thumb_set_instruction_word
helpers throughout.

Style cleanup (missing spaces).

Move Thumb MOVW/MOVT handlers into Thumb relocation section of file.

Leif Lindholm c0f529ea67 arm: implement additional relocations generated by gcc 4.9 at -O3
GCC 4.9 also generates R_ARM_THM_MOVW_ABS_NC and R_ARM_THM_MOVT_ABS,
as an alternative to ABS32.

Leif Lindholm 2da4171eab configure.ac: don't use -msoft-float for arm64
aarch64 toolchains do not support the -msoft-float option added by
commit 3661261f. Insted, for arm64 use -march=armv8-a+nofp+nosimd.

Leif Lindholm 004a2b1efd efi: check *path non-null before grub_strrchr
The EFI version of grub_machine_get_bootlocation crops the boot image
name back to the last / in order to get a directory path. However, it
does not check that *name is actually set before calling grub_strrchr
to do this, and neither does grub_strrchr before dereferencing a NULL
pointer.

Parent function, grub_set_prefix_and_root, does check the pointer
before using.

Leif Lindholm 4d21c10199 arm64: set correct length of device path end entry
The length of the Device Path End entry in the grub_linux_boot()
function was incorrectly set to 0. This triggers an assert failure
in debug builds of Tianocore.

Set it to sizeof (grub_efi_device_path_t).

Leif Lindholm 593865b907 arm: fix u-boot port syscall interface va_arg handling
Commit c9cd02c broke the u-boot syscall API for va_args that spill over
to the stack, causing the disk support to stop working. This patch
resolves the problem, while keeping the new, cleaner transition_space
handling.
