5bda44d7f9 * grub-core/kern/arm/cache_armv6.S: Remove .arch directive. 
As these functions are used on pre-ARMv6 CPUs as well we don't want
	to make assembler assume that architecture is higher than default one.

bbc52c228f Enable cache on ARM U-Boot port. 
Without it the port is reidiculously slow.

8c534b85f1 Revamp relocation handling. 
Move more code to common dl.c. Add missing veneers for arm and arm64.
	Decreases kernel size by 70 bytes on i386-pc (40-50 compressed)

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.

2bdd07195c * grub-core/kern/arm/cache.c (probe_caches): Move asm part to ... 
* grub-core/kern/arm/cache_armv6.S: ... here. This allows this
