We could hit this problem with crashkernel booting that uses kexec loading kernel above 4GiB.

| | | | | | | | | | | | | Add PHYSICAL_START kernel configuration parameter to set the address at which the kernel should be loaded. It has been observed on an sh7757lcr that simply modifying MEMORY_START does not achieve this goal for 32bit sh.

* sh: Remove compressed kernel libgcc dependency.Paul Mundt2011-06-061-3/+19
| | | | | | | | | | | | | | | SH-2A is unable to combine the kernel and libgcc objects due to fundamental disagreements over FDPIC settings. As the kernel already contains all of the libgcc bits broken out, there's not much need to bother with the linking anymore, as everything can already be derived from the lib dir. This simply plugs in the necessary bits to ensure that everything is built uniformly, enabling us to wean the compressed build off of explicit libgcc linking.

* mmc, sh: Remove sh_mmcif_boot_slurp()Simon Horman2010-12-081-1/+3
| | | | | | | | | | | | | | | | As the only caller of sh_mmcif_boot_do_read() is sh_mmcif_boot_slurp() the configuration portion of sh_mmcif_boot_slurp() can be merged into sh_mmcif_boot_do_read(). Once this is done sh_mmcif_boot_slurp() is only a call to sh_mmcif_boot_do_read() with platform specific information - the offset that images are stored on MMC. So make the sh_mmcif_boot_do_read() call directly from platform code and remove sh_mmcif_boot_slurp() altogether.

| | | | | | | | | | | | | | | | | | | | | | Update the SH kernel to keep SR.BL set until the VBR register has been initialized. Useful to allow boot of the kernel even though exceptions are pending. Without this patch there is a window of time when exceptions such as NMI are enabled but no exception handlers are installed. This patch modifies both the zImage loader and the actual kernel to boot with BL=1, but the zImage loader is modfied in such a way that the init_sr value is unchanged to not break the zImage loader provided by kexec.

* | sh: Merge legacy and dynamic PMB modes.Paul Mundt2010-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.Paul Mundt2010-01-282-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <lethal@linux-sh.org>
* | sh: fixed PMB mode refactoring.Paul Mundt2010-01-131-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* kbuild: use INSTALLKERNEL to select customized installkernel scriptSam Ravnborg2009-09-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 immediatesStuart Menefy2009-08-241-1/+1
| | | | | | | | | | | | | | | The SH instruction set has several instructions which accept an 8 bit immediate operand.
