From: Stephen Warren swarren@nvidia.com
The next patch will call fdt_translate_address() from somewhere with a "const void *blob" rather than a "void *blob", so fdt_translate_address() must accept a const pointer too. Constify the minimum number of function parameters to achieve this.
Signed-off-by: Stephen Warren swarren@nvidia.com Acked-by: Simon Glass sjg@chromium.org --- Re-sending since these didn't show up in patchwork for some reason.
This series will be a dependency for the Tegra BPMP driver.
