![]() This patch adds support for Local Chip Addressing (LCA). In a multi-chip system, enablig LCA allows each GIC Distributor to maintain its own version of routing table. This feature is activated when the GICD_CFGID.LCA bit is set to 1. The existing `gic600_multichip_data` data structure did not account for the LCA feature. To support LCA: - `rt_owner_base` is replaced by `base_addrs[]`. This is required because each GICD in the system needs to be configured independently, and their base addresses must be passed to the driver. - `chip_addrs` is changed from 1D to 2D array to store the routing table for each chip's GICD. The entries in `chip_addrs` are configuration dependent, as the GIC specification does not enforce this. On a multi-chip platform with chip count N where LCA is enabled by default, the `gic600_multichip_data` structure should contain all copies of the routing table (N*N entries). On platforms where LCA is not supported, only the first sub-array with N entries is required. The function signature of `gic600_multichip_init` remains unchanged, but if the LCA feature is enabled, the driver will expect the routing table configuration in the described format.
