From 7e0dea6317dc74f8aba8c91d0f8e8a7237261c49 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 20 Feb 2019 18:39:22 -0800 Subject: symbols.h: Add macro to define memlayout region symbols When was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.
