From 10cb54de2c97847cd5b6b2df4e8b359e65266181 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Wed, 23 Nov 2011 14:46:36 +1000 Subject: m68knommu: hard set the ColdFire MBAR register on startup The ColdFire MBAR register that holds the mapping of the peripheral region on some ColdFire CPUs is configurable. It can be configured at some address different to that of the bootloader that loaded the kernel. So hard set the MBAR register mapping at kernel startup time.

Clean it all up and use the well defined linker script support macros. Support is maintained for building both ROM/FLASH based and RAM based setups. No major changes to section layouts, though the rodata section is now lumped in with the read/write data section.

But the underlying code to support it, update_persistent_clock(), doesn't end up doing anything on the currently supported non-MMU platforms. No platforms supply the necessary function support for writing back the RTC. So lets remove this option and support code. This also brings m68knommu in line with the m68k, which doesn't enabled this switch either.

The non-MMU m68k code has never supported FPU hardware. To help in merging common code create a configation setting that signifies if we are builing in FPU support or not. This switch, CONFIG_FPU, is set as per the current use cases. So it is always enabled if CONFIG_MMU is set, and disabled otherwise. With a little extra code it will be possible to disable it on the classic m68k platforms as well, and to enable it on non-MMU platforms that do have hardware FPU.

Only a few minor details differ between the two. The majority of the difference is to deal with having or wanting hardware FPU support. So merge them back into a single process.c file.
