sh: Merge legacy and dynamic PMB modes.

2010-02-18T09:13:51Z

This implements a bit of rework for the PMB code, which permits us to kill off the legacy PMB mode completely. Rather than trusting the boot loader to do the right thing, we do a quick verification of the PMB contents to determine whether to have the kernel setup the initial mappings or whether it needs to mangle them later on instead. If we're booting from legacy mappings, the kernel will now take control of them and make them match the kernel's initial mapping configuration. This is accomplished by breaking the initialization phase out in to multiple steps: synchronization, merging, and resizing. With the recent rework, the synchronization code establishes page links for compound mappings already, so we build on top of this for promoting mappings and reclaiming unused slots. At the same time, the changes introduced for the uncached helpers also permit us to dynamically resize the uncached mapping without any particular headaches. The smallest page size is more than sufficient for mapping all of kernel text, and as we're careful not to jump to any far off locations in the setup code the mapping can safely be resized regardless of whether we are executing from it or not.

sh: Kill off superfluous sh_bios references from compressed loader.

2010-01-28T09:26:37Z

The VBR value needs to be initialized in order for any of the bios trapping to work, and as we don't do that until slightly later in the boot process, this has no real chance of working. The only reason for using this in the past was due to the fact that early serial initialization wasn't possible, but now that early sh-sci is supported by everyone, there's no longer any reason to support the sh_bios hacks in the first place. Given that, we just kill off the references completely. Signed-off-by: Paul Mundt

sh: fixed PMB mode refactoring.

2010-01-13T09:31:48Z

This introduces some much overdue chainsawing of the fixed PMB support. fixed PMB was introduced initially to work around the fact that dynamic PMB mode was relatively broken, though they were never intended to converge. The main areas where there are differences are whether the system is booted in 29-bit mode or 32-bit mode, and whether legacy mappings are to be preserved. Any system booting in true 32-bit mode will not care about legacy mappings, so these are roughly decoupled. Regardless of the entry point, PMB and 32BIT are directly related as far as the kernel is concerned, so we also switch back to having one select the other. With legacy mappings iterated through and applied in the initialization path it's now possible to finally merge the two implementations and permit dynamic remapping overtop of remaining entries regardless of whether boot mappings are crafted by hand or inherited from the boot loader.

sh: include empty zero page in romImage

2009-12-04T07:26:20Z

This patch updates the romImage code to include the empty_zero_page contents from vmlinux. Without this patch the empty zero page is lef uninitialized. Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt

sh: Obliterate the P1 area macros

2009-10-10T12:51:02Z

Replace the use of PHYSADDR() with __pa(). PHYSADDR() is based on the idea that all addresses in P1SEG are untranslated, so we can access an address's physical page as an offset from P1SEG. This doesn't work for CONFIG_PMB/CONFIG_PMB_FIXED because pages in P1SEG and P2SEG are used for PMB mappings and so can be translated to any physical address. Likewise, replace a P1SEGADDR() use with virt_to_phys(). Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt
