* m68k: select CONFIG_GENERIC_ATOMIC64 for all m68k CPU typesGreg Ungerer2012-08-172-4/+1
| | | | | | | | | | There is no specific atomic64 support code for any m68k CPUs, so we should select CONFIG_GENERIC_ATOMC64 for all. Remove the existing per CPU selection of this and select it for all m68k.

| * m68k: Remove never used asm/shm.hPaul Bolle2012-06-271-31/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m68k's asm/shm.h header has been part of the tree ever since m68k support got added in v1.3.94. (It started as /include/asm-m68k/shm.h and moved to its current location a few years ago.) It seems it was never used: no file ever included it and nothing used the macros it defines. (Actually, from v2.5.46 until v2.6.29-rc3 it was included by m68knommu's asm/shm.h. But that header was just a very thin wrapper for this header and was itself unused too.) This header can safely be removed. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

| * m68k: Remove five unused headersPaul Bolle2012-06-275-545/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are five entirely unused headers in arch/m68k/include/asm. Nothing includes these headers. And a few tests found no hits for the things they provide (which makes sense). MC68332.h, mac_mouse.h, and mcfmbus.h are all unused since at least v2.6.12-rc2 (I didn't bother looking further back than that). apollodma.h is unused since v2.6.19: commit 2ed0ce5b57950a620155433c62a5a02a067f1376 ("m68k/Apollo: Remove obsolete arch/m68k/apollo/dma.c") removed the last file interested in that header. And everything interested in <asm/sbus.h> was removed in the v2.6.28 release cycle. The last occurrence of "sbus.h" was deleted with commit 0c0db98b50ed1217c0dbf4051722034ba314d06e ("sparc: Remove Documentation/sparc/sbus_drivers.txt"). I'm not sure whether anything relevant for m68k was included in v2.6.27, but it doesn't really matter.

It also adds some simple clk definitions and very simple minded power management. The gpio code is tweeked and some additional devices are added to devices.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mcf_gpio_chips. If we're not connecting external GPIO extenders via i2c or spi or whatever, we probably don't need GPIOLIB. If we provide an alternate implementation of the GPIOLIB functions to use when only on-chip GPIO is needed, we can change ARCH_REQUIRE_GPIOLIB to ARCH_WANTS_OPTIONAL_GPIOLIB so that GPIOLIB becomes optional. The downside is that in the GPIOLIB=n case, we lose all error checking done by gpiolib, ie multiply allocating the gpio, free'ing gpio etc., so that the only checking that can be done is if we reference a gpio on an external part. Targets that need the extra error checking can still select GPIOLIB=y. For the case where GPIOLIB=y, we can simplify the table of gpio chips to use a single chip, eliminating the tables of chips in the 5xxx.c files. The original motivation for the definition of multiple chips was to match the way many of the Coldfire variants defined their gpio as a spare array in memory. However, all this really gains us is some error checking when we request a gpio, gpiolib can check that it doesn't fall in one of the holes. If thats important, I think we can still come up with a better way of accomplishing that. Also in this patch is some general cleanup and reorganizing of the gpio header files (I'm sure I must have had a reason why I sometimes used a prefix of mcf_gpio and other times mcfgpio but for the life of me I can't think of it now).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ret_from_excption code is referenced by its function name, or by a label set at the start of its code. The non-MMU code can share some of this code if we make direct calls to ret_from_exception instead of the associated label. The effected function paths are: buserr, trap and ret_from_fork. So change these to branch directly to ret_from_exception. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>

* | | | net: add support for NS8390 based eth controllers on some ColdFire CPU boardsGreg Ungerer2012-07-121-120/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of older ColdFire CPU based boards use NS8390 based network controllers. Most use the Davicom 9008F or the UMC 9008F. This driver provides the support code to get these devices working on these platforms. Generally the NS8390 based eth device is direct connected via the general purpose bus of the ColdFire CPU. So its addressing and interrupt setup is fixed on each of the different platforms (classic platform setup). This driver is based on the other drivers/net/ethernet/8390 drivers, and includes the lib8390.c code. It uses the existing definitions of the board NS8390 device addresses, interrupts and access types from the arch/m68k/include/asm/mcf8390.h, but moves the IO access functions into the driver code and out of that header.

For example when compiling for ColdFire I get: LD vmlinux drivers/built-in.o: In function `fec_probe': fec.c:(.devinit.text+0x1e0): undefined reference to `devm_clk_get' Define a simple devm_clk_get() function for the m68knommu architecture.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The assembler entry code calls directly to the syscall_trace_enter() and syscall_trace_leave() functions. But currently they are conditionaly compiled out for the non-MMU classic m68k CPU types (so 68328 for example), resulting in a link error: LD vmlinux arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x1c): undefined reference to `syscall_trace_enter' arch/m68k/platform/68328/built-in.o: In function `do_trace': (.text+0x4c): undefined reference to `syscall_trace_leave' Change the conditional check that includes these functions to be true for the !defined(CONFIG_MMU) case as well.
