So far kernel command line arguments could be passed in by a bootloader or defined as CONFIG_CMDLINE, which completely overwriting the first one. This change allows a developer to declare selected kernel parameters in a kernel configuration (eg. project-specific defconfig), retaining possibility of passing others by a bootloader. The obvious examples of the first type are MTD partition or bigphysarea-like region definitions, while "debug" option or network configuration should be given by a bootloader or a JTAG boot script.

This adds a family member to struct sh_cpuinfo, which allows us to fall back more on the probe routines to work out what sort of subtype we are running on. This will be used by the CPU cache initialization code in order to first do family-level initialization, followed by subtype-level optimizations. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments. The sh7785 clock code and the sh7785lcr board code are updated to reflect the new shared mode pins.

Add mode pin support for the SuperH architecture V2. With this patch applied the board code can add their own function to export the cpu mode pin configuration. In most cases this will be a constant bitmap, but boards that allow reading this from a register can instead read out the pin state from hardware. The code warns if a pin is tested but no board specific mode pin function has been provided. Signed-off-by: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores that implement the PTAEX register and respective functionality. Presently only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs). The main change is in how the PTE is written out when loading the entry in to the TLB, as well as in how the TLB entry is selectively flushed. While SH-X2 extended mode splits out the memory-mapped U and I-TLB data arrays for extra bits, extended ASID mode splits out the address arrays. While we don't use the memory-mapped data array access, the address array accesses are necessary for selective TLB flushes, so these are implemented newly and replace the generic SH-4 implementation. With this, TLB flushes in switch_mm() are almost non-existent on newer parts. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This fixes a problems with the set up of Linux memory: - When reserving memory at boot time, the code previously reserved the bottom page of memory, and then from one page up to the end of the bootmap. This had the desired effect, but was strictly speaking wrong, as the one page was actually whatever CONFIG_ZERO_PAGE_OFFSET had been set to.

This patchset adds a flags variable to reserve_bootmem() and uses the BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions between crashkernel area and already used memory. This patch: Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE. If that flag is set, the function returns with -EBUSY if the memory already has been reserved in the past. This is to avoid conflicts. Because that code runs before SMP initialisation, there's no race condition inside reserve_bootmem_core().
