Currently, the firmware tables are parsed by the virtual timer and virtual GIC code in order to configure them correctly. However, the parsing of those tables is already done in the GIC and arch timer drivers. This patch series introduces new helpers to retrieve the information from the different drivers in order to avoid duplication of the parsing code. To make the merge easier via the different trees, each patch modifies a single subsystem. For all the changes see the different patches.
