From d3e10ebd354928d56ba660cd2ea14af1663702a2 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 24 Jun 2025 13:17:19 +0100 Subject: [legacy] Allocate legacy driver .bss-like segments at probe time Some legacy drivers use large static allocations for transmit and receive buffers. To avoid bloating the .bss segment, we currently implement these as a single common symbol named "_shared_bss" (which is permissible since only one legacy driver may be active at any one time). Switch to dynamic allocation of these .bss-like segments, to avoid the requirement for using common symbols.
