| Subject: powerpc/52xx: Fix an invalid ASM expression ('addi' used instead of |
| 'add') |
| |
| From: Christophe Leroy <christophe.leroy@csgroup.eu> |
| |
| [ Upstream commit 8a87a507714386efc39c3ae6fa24d4f79846b522 ] |
| |
| AS arch/powerpc/platforms/52xx/lite5200_sleep.o |
| arch/powerpc/platforms/52xx/lite5200_sleep.S: Assembler messages: |
| arch/powerpc/platforms/52xx/lite5200_sleep.S:184: Warning: invalid register expression |
| |
| In the following code, 'addi' is wrong, has to be 'add' |
| |
| /* local udelay in sram is needed */ |
| udelay: /* r11 - tb_ticks_per_usec, r12 - usecs, overwrites r13 */ |
| mullw r12, r12, r11 |
| mftb r13 /* start */ |
| addi r12, r13, r12 /* end */ |
