x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parameters
As of today, the proposal of adding "acpi_rsdp_addr" to the kernel boot protocol does not make its way to the kernel mainline. This creates some confusion if we leave it in the U-Boot code base. Remove it for now until we have a clear picture with kernel upstream. Note this eventually does a partial revert to commit 3469bf427454 ("x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters") Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Reviewed-by: Simon Glass <sjg@chromium.org>
