2016-12-05m68knommu: platform support for i2c devices on ColdFire SoCSteven King
These changes based on work by Steven King <sfking@fdwdc.com> to support the i2c hardware modules on ColdFire SoC family devices. This is the per SoC hardware support. Contains a common platform device setup. Each of the SoC family members tends to have some minor local setup required to initialize the module. But all ColdFire family members use the same i2c hardware module. This i2c hardware module is the same as used in the Freescale iMX ARM based family of SoC devices. Steven's original patches were based on using a new and different i2c-coldfire.c driver. But this is not neccessary as we can use the existing Linux i2c-imx.c driver with no change required to it. And this patch is now based on using the existing i2c-imx driver. This patch only contains the ColdFire platform changes.

2016-09-26m68k: move ColdFire _bootmem_alloc codeGreg Ungerer
The early ColdFire bootmem_alloc() code is currently only included in the board support for the Coldire 54xx platforms. It will be used on all ColdFire MMU enabled platforms as others are supported. So move the mcf54xx_bootmem_alloc() function to be generally available to all MMU enabled ColdFire parts (and use a more generic name for it). Signed-off-by: Greg Ungerer <gerg@linux-m68k.org>
2015-11-22m68k/mm: m54xx - Add missing initialization of max_pfnGeert Uytterhoeven
If max_pfn is not initialized, the various /proc/kpage* files are empty, and selftests/vm/mlock2-tests will fail. max_pfn is also used by the block layer to calculate DMA masks.

2014-09-29m68k: fix crufty ColdFire intro commentsGreg Ungerer
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.

2014-09-29m68k: move coldfire platform codeGreg Ungerer
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 <gerg@uclinux.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org>
