[PATCH] ARM: always enable AEABI for ARMv6+
From: Russell King <hidden>
Date: 2017-06-22 09:12:31
Always enable AEABI for ARMv6+, as these use the double-word exclusives which must be passed an even register to avoid errors such as: /tmp/ccG2rCwe.s:905: Error: even register required -- `ldrexd r5,r6,[r7]' /tmp/ccG2rCwe.s:909: Error: even register required -- `strexd sl,r3,r4,[r7]' Signed-off-by: Russell King <redacted> --- arch/arm/Kconfig | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
