| Subject: powerpc/boot: Specify ABI v2 when building an LE boot wrapper |
| |
| From: Benjamin Herrenschmidt <benh@kernel.crashing.org> |
| |
| commit 655471f54c2e395ba29ae4156ba0f49928177cc1 upstream. |
| |
| The kernel does it, not the boot wrapper, which breaks with some |
| cross compilers that still default to ABI v1. |
| |
| Fixes: 147c05168fc8 ("powerpc/boot: Add support for 64bit little endian wrapper") |
