Re: [U-Boot] [PATCH v3] armv8: aarch64: Fix the warning about x1-x3 nonzero issue

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.

Changes in v3:

• Remove redundant code.

Changes in v2:

• Add another input argument 4 for armv8_switch_to_el2 and armv8_switch_to_el1.
• Give up the previous way to adjust the parameters to transfer and make sure x3 is zero.

Applied to fsl-qoriq master, awaiting upstream. Thanks.
