MPC85xx chips report the wrong value in feature reporting register, and that causes the following oops: Unable to handle kernel paging request for data at address 0x00000c00 Faulting instruction address: 0xc0019294 Oops: Kernel access of bad area, sig: 11 [#1] MPC8569 MDS Modules linked in: [...] NIP [c0019294] mpic_set_irq_type+0x2f0/0x368 LR [c0019124] mpic_set_irq_type+0x180/0x368 Call Trace: [ef851d60] [c0019124] mpic_set_irq_type+0x180/0x368 (unreliable) [ef851d90] [c007958c] __irq_set_trigger+0x44/0xd4 [ef851db0] [c007b550] set_irq_type+0x40/0x7c [ef851dc0] [c0004a60] irq_create_of_mapping+0xb4/0x114 [ef851df0] [c0004af0] irq_of_parse_and_map+0x30/0x40 [ef851e20] [c0405678] fsl_of_msi_probe+0x1a0/0x328 [ef851e60] [c02e6438] of_platform_device_probe+0x5c/0x84 [...] This is because mpic_alloc() assigns wrong values to mpic->isu_{size,shift,mask}, and things eventually break when _mpic_irq_read() is trying to use them. This patch fixes the issue by enabling MPIC_BROKEN_FRR_NIRQS quirk. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> |
