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: 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

kbuild: use INSTALLKERNEL to select customized installkernel script

2009-09-20T10:18:14Z

Replace the use of CROSS_COMPILE to select a customized installkernel script with the possibility to set INSTALLKERNEL to select a custom installkernel script when running make: make INSTALLKERNEL=arm-installkernel install With this patch we are now more consistent across different architectures - they did not all support use of CROSS_COMPILE. The use of CROSS_COMPILE was a hack as this really belongs to gcc/binutils and the installkernel script does not change just because we change toolchain. The use of CROSS_COMPILE caused troubles with an upcoming patch that saves CROSS_COMPILE when a kernel is built - it would no longer be installable. [Thanks to Peter Z. for this hint] This patch undos what Ian did in commit: 0f8e2d62fa04441cd12c08ce521e84e5bd3f8a46 ("use ${CROSS_COMPILE}installkernel in arch/*/boot/install.sh") The patch has been lightly tested on x86 only - but all changes looks obvious.

sh: Remove implicit sign extension from assembler immediates

2009-08-24T08:09:53Z

The SH instruction set has several instructions which accept an 8 bit immediate operand. For logical instructions this operand is zero extended, for arithmetic instructions the operand is sign extended. After adding an option to the assembler to check this, it was found that several pieces of assembly code were assuming this behaviour, and in one case getting it wrong. So this patch explicitly sign extends any immediate operands, which makes it obvious what is happening, and fixes the one case which got it wrong.
