HVC call makes use of 6 mandatory arguments rather than 7 in the same way as SMC calls. The 7th argument is optional (Client ID) for both HVC and SMC but is implemented as 16-bit parameter and register R7 or W7. The aim of this patch is just fix compilation error due to an invalid asm code in the HVC call so that's why the 7th
argument is removed.
The issue does not report any error in a normal build as hvc_call is not used at all and is optimized by the compiler. Using -O0 triggers the error so the patch is intended to fix issues on a ongoing effor to build U-Boot with -O0.

Thanks for the review. Do I need to CC somebody else to the patch be
accepted?
No, but I'm inclined currently to take for for the next release rather than right now, unless there's an important argument I'm missing? Which happens more than I'd care to admit ;)
No rush, I'm pretty new contributor and just wondering if something else was missing after Alexander's Review.
