m68k: set dma and coherent masks for platform FEC ethernets

2018-05-30T05:47:40Z

[ Upstream commit f61e64310b75733d782e930d1fb404b84699eed6 ] As of commit 205e1b7f51e4 ("dma-mapping: warn when there is no coherent_dma_mask") the Freescale FEC driver is issuing the following warning on driver initialization on ColdFire systems: WARNING: CPU: 0 PID: 1 at ./include/linux/dma-mapping.h:516 0x40159e20 Modules linked in: CPU: 0 PID: 1 Comm: swapper Not tainted 4.16.0-rc7-dirty #4 Stack from 41833dd8: 41833dd8 40259c53 40025534 40279e26 00000003 00000000 4004e514 41827000 400255de 40244e42 00000204 40159e20 00000009 00000000 00000000 4024531d 40159e20 40244e42 00000204 00000000 00000000 00000000 00000007 00000000 00000000 40279e26 4028d040 40226576 4003ae88 40279e26 418273f6 41833ef8 7fffffff 418273f2 41867028 4003c9a2 4180ac6c 00000004 41833f8c 4013e71c 40279e1c 40279e26 40226c16 4013ced2 40279e26 40279e58 4028d040 00000000 Call Trace: [<40025534>] 0x40025534 [<4004e514>] 0x4004e514 [<400255de>] 0x400255de [<40159e20>] 0x40159e20 [<40159e20>] 0x40159e20 It is not fatal, the driver and the system continue to function normally. As per the warning the coherent_dma_mask is not set on this device. There is nothing special about the DMA memory coherency on this hardware so we can just set the mask to 32bits in the platform data for the FEC ethernet devices.

m68knommu: fix size of address field for 5272 interrupt controller

2014-09-28T23:18:36Z

Picked up by the 0-day buidler: All warnings: >> arch/m68k/coldfire/intc-5272.c:46:20: warning: large integer implicitly truncated to unsigned type [-Woverflow] /*MCF_IRQ_EINT1*/ { .icr = MCFSIM_ICR1, .index = 28, .ack = 1, }, ... The problem stems from the changes to make all ColdFire register addresses absolute, in commit d72a5abb ("make remaining ColdFire 5272 register definitions absolute"). That change did not take into account that the addresses were stored as offsets in the irqmap of the intc-5272.c code. Make the field that now stores register addresses big enough to hold addresses.

m68k: fix crufty ColdFire intro comments

2014-09-28T23:18:34Z

Quite a few of the ColdFire specific support files have a pathname in the title comments of the file. These files have moved around a bit over the years, and most are no longer accurate. Remove the pathname and fix the comments to include at least a short description of the files contents. Signed-off-by: Greg Ungerer Acked-by: Geert Uytterhoeven

m68k: move coldfire platform code

2014-09-28T23:18:34Z

Move the m68k ColdFire platform support code directory to be with the existing m68k platforms. Although the ColdFire is not a platform as such, we have always kept all its support together. No reason to change that as this time. Signed-off-by: Greg Ungerer Acked-by: Geert Uytterhoeven
