* armv8: aarch64: Fix the warning about x1-x3 nonzero issueAlison Wang2017-01-18-4/+4
| | | | | | | | | | | | | For 64-bit kernel, there is a warning about x1-x3 nonzero in violation of boot protocol. To fix this issue, input argument 4 is added for armv8_switch_to_el2 and armv8_switch_to_el1. The input argument 4 will be set to the right value, such as zero.

* armv8: Support loading 32-bit OS in AArch32 execution stateAlison Wang2016-11-22-1/+8
| | | | | | | | | | | | | To support loading a 32-bit OS, the execution state will change from AArch64 to AArch32 when jumping to kernel. The architecture information will be got through checking FIT image, then U-Boot will load 32-bit OS or 64-bit OS automatically.

* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-23-1/+1
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.
