From c386ee06e5dbc89b69a0a58edace3f54fd5e2b8f Mon Sep 17 00:00:00 2001 From: Feng Tang <feng.tang@intel.com> Date: Mon, 28 Feb 2022 09:44:04 +0800 Subject: [PATCH] lib/Kconfig.debug: add ARCH dependency for FUNCTION_ALIGNMENT option
0Day robots reported there is compiling issue for 'csky' ARCH when CONFIG_DEBUG_FORCE_DATA_SECTION_ALIGNED is enabled:
" All errors (new ones prefixed by >>):
{standard input}: Assembler messages: >> {standard input}:2277: Error: pcrel offset for branch to .LS000B too far (0x3c) "
Which has been discussed in [1]. And as there is no solution for csky yet, add some dependency for this config to limit it to several ARCHs which have no compiling issue so far.
