* m68k: merge m68k and m68knommu arch directoriesGreg Ungerer2011-03-25126-21182/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a lot of common code that could be shared between the m68k and m68knommu arch branches. It makes sense to merge the two branches into a single directory structure so that we can more easily share that common code. This is a brute force merge, based on a script from Stephen King <sfking@fdwdc.com>, which was originally written by Arnd Bergmann <arnd@arndb.de>. > The script was inspired by the script Sam Ravnborg used to merge the > includes from m68knommu. For those files common to both arches but > differing in content, the m68k version of the file is renamed to > <file>_mm.<ext> and the m68knommu version of the file is moved into the > corresponding m68k directory and renamed <file>_no.<ext> and a small > wrapper file <file>.<ext> is used to select between the two version. Files > that are common to both but don't differ are removed from the m68knommu > tree and files and directories that are unique to the m68knommu tree are > moved to the m68k tree. Finally, the arch/m68knommu tree is removed. > > To select between the the versions of the files, the wrapper uses > > #ifdef CONFIG_MMU > #include <file>_mm.<ext> > #else > #include <file>_no.<ext> > #endif On top of this file merge I have done a simplistic merge of m68k and m68knommu Kconfig, which primarily attempts to keep existing options and menus in place. Other than a handful of options being moved it produces identical .config outputs on m68k and m68knommu targets I tested it on. With this in place there is now quite a bit of scope for merge cleanups in future patches. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* m68knommu: introduce little-endian bitopsAkinobu Mita2011-03-241-4/+0
| | | | | | | | | | | | | | | | | Introduce little-endian bit operations by renaming native ext2 bit operations. The ext2 bit operations are kept as wrapper macros using little-endian bit operations to maintain bisectability until the conversions are finished.

* bitops: introduce CONFIG_GENERIC_FIND_BIT_LEAkinobu Mita2011-03-241-0/+4
| | | | | | | | | | | | | | | | | | This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic implementation of find_*_bit_le() in lib/find_next_bit.c or not. For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which enable CONFIG_GENERIC_FIND_NEXT_BIT. But m68knommu wants to define own faster find_next_zero_bit_le() and continues using generic find_next_{,zero_}bit().

| * m68knommu: external interrupt support to ColdFire intc-simr controllerGreg Ungerer2011-03-151-4/+110
| | | | | | | | | | | | | | | | | | | | The EDGE Port module of some ColdFire parts using the intc-simr interrupt controller provides support for 7 external interrupts. These interrupts go off-chip (that is they are not for internal peripherals). They need some special handling and have some extra setup registers. Add code to support them.

| * m68knommu: remove ColdFire CLOCK_DIV config optionGreg Ungerer2011-03-151-11/+0
| | | | | | | | | | | | | | | | | | | | The reality is that you do not need the abiltity to configure the clock divider for ColdFire CPUs. It is a fixed ratio on any given ColdFire family member. It is not the same for all ColdFire parts, but it is always the same in a model range. So hard define the divider for each supported ColdFire CPU type and remove the Kconfig option.

| | | | | | | | | | | | | | | | | | | | | | | | Most ColdFire CPUs have an internal peripheral set that can be mapped at a user selectable address. Different ColdFire parts either use an MBAR register of an IPSBAR register to map the peripheral region. Most boards use the Freescale default mappings - but not all. Make the setting of the MBAR or IPSBAR register configurable. And only make the selection available on the appropriate ColdFire CPU types. Signed-off-by: Greg Ungerer <gerg@uclinux.org>

| | | | | | | | | | | | | | | | | | | | | | | | In some of the RAM size autodetection code on ColdFire CPU startup we reference DRAM registers relative to the MBAR register. Not all of the supported ColdFire CPUs have an MBAR, and currently this works because we fake an MBAR address on those registers. In an effort to clean this up, and eventually remove the fake MBAR setting make the DRAM register address definitions actually contain the MBAR (or IPSBAR as appropriate) value as required.

| | | | | | | | | | | | | | | | | | | | | | | | The PIT hardware timer module used in some ColdFire CPU's is not always addressed relative to an IPSBAR register. Parts like the ColdFire 5207 and 5208 have fixed peripheral addresses. So lets not define the register addresses of the PIT relative to an IPSBAR definition. Move the base address definitions into the per-part headers. This is a lot more consistent since all the other peripheral base addresses are defined in the per-part header files already.

| * m68knommu: remove kludge seting of MCF_IPSBAR for ColdFire 54xxGreg Ungerer2011-03-151-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ColdFire 54xx family shares the same interrupt controller used on the 523x, 527x and 528x ColdFire parts, but it isn't offset relative to the IPSBAR register. The 54xx doesn't have an IPSBAR register. By including the base address of the peripheral registers in the register definitions (MCFICM_INTC0 and MCFICM_INTC1 in this case) we can avoid having to define a fake IPSBAR for the 54xx. And this makes the register address definitions of these more consistent, the majority of the other register address defines include the peripheral base address already.

| * m68knommu: 5772: Replace private irq flow handlerThomas Gleixner2011-03-151-4/+1
| | | | | | | | | | | | | | | | | | | | | | That handler lacks the minimal checks for action being zero etc. Keep the weird flow - ack before handling - intact and call into handle_simple_irq which does the right thing.

* | m68knommu: add optimize memmove() functionGreg Ungerer2011-02-162-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an m68k/coldfire optimized memmove() function for the m68knommu arch. This is the same function as used by m68k. Simple speed tests show this is faster once buffers are larger than 4 bytes, and significantly faster on much larger buffers (4 times faster above about 100 bytes). This also goes part of the way to fixing a regression caused by commit ea61bc461d09e8d331a307916530aaae808c72a2 ("m68k/m68knommu: merge MMU and non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is the 68x328 and 68360 families). They currently have no memmove() fucntion defined, since there was none in the m68knommu/lib functions. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
* | m68knommu: fix use of un-defined _TIF_WORK_MASKGreg Ungerer2011-02-083-3/+0
|/ | | | | | | | | | | | | | The _TIF_WORK_MASK definition was removed in the clean up of MMU and non-MMU arch/m68k/include/asm/thread_info*.h files (this was commit cddafa3500fde4a07e5bf899ec97a04069f8f7ce, "merge MMU and non-MMU thread_info.h"). It didn't get cleaned out of the entry.S code for the 68328 and 68360 based platforms. And it was replaced by a hard coded constant mask for coldfire platforms. There is currently no need to mask any of these bits, so fix all uses (and former uses) to check for any non-zero value. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
