2023-10-25sh: machvec: Remove custom ioport_{un,}map()Arnd Bergmann1-5/+0
These functions were only used on the microdev board that is now gone, so remove them to simplify the ioport handling. This could be further simplified to use the generic I/O port accessors now.

2020-10-25treewide: Convert macro and uses of __section(foo) to __section("foo")Joe Perches1-1/+1
Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

2014-04-07Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAPUwe Kleine-König1-1/+1
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <[email protected]> Acked-by: Arnd Bergmann <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2012-05-21sh: Kill off machvec IRQ hinting.Paul Mundt1-1/+0
Everything is using sparseirq these days, so we have no need to arbitrarily size nr_irqs ahead of time. The legacy IRQ pre-allocation likewise has no meaning for us, so that's killed off too. We now depend on nr_irqs expansion by the generic hardirq layer instead. It's also worth noting that the majority of boards had completely bogus values for their nr_irqs relative to their CPU and configurations, so this ends up correcting behaviour for quite a few platforms.

2011-01-11sh: Add a machvec callback for early memblock reservations.Paul Mundt1-0/+1
This adds in a callback to the machvec to allow platforms to do early reservations through memblock. Signed-off-by: Paul Mundt <[email protected]>
2010-11-01sh: machvec IO death.Paul Mundt1-21/+0
This takes a bit of a sledgehammer to the machvec I/O routines. The iomem case requires no special casing and so can just be dropped outright. This only leaves the ioport casing for PCI and SuperIO mangling. With the SuperIO case going through the standard ioport mapping, it's possible to replace everything with generic routines. With this done the standard I/O routines are tidied up and NO_IOPORT now gets default-enabled for the vast majority of boards. Signed-off-by: Paul Mundt <[email protected]>
2010-06-02sh: support for platforms without PIO.Paul Mundt1-4/+5
This extends some of the existing special casing for HAS_IOPORT platforms and gets it to the point where platforms can begin to conditionally select it. The major changes here are that the PIO routines themselves go away completely, including all of the machvec port mapping wrappers. With this in place it's possible for any non-machvec abusing platform to disable PIO completely. At present this is left as an opt-in until the abusers are the odd ones out instead of the majority.

2010-05-10sh: enable LMB region setup via machvec.Paul Mundt1-0/+2
This plugs in a memory init callback in the machvec to permit boards to wire up various bits of memory directly in to LMB. A generic machvec implementation is provided that simply wraps around the normal Kconfig-derived memory start/size. Signed-off-by: Paul Mundt <[email protected]>

2009-06-01sh: boot word / mode pin support V2Magnus Damm1-0/+1
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: Magnus Damm <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2009-05-13sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt1-0/+2
This moves out the old legacy CPG clocks to their own file, and converts over the existing users. With these clocks going away and each CPU dealing with them on their own, CPUs can gradually move over to the new interface. Signed-off-by: Paul Mundt <[email protected]>

2008-10-04sh: More I/O routine overhauling.Paul Mundt1-7/+0
This tidies up a lot of the PIO/MMIO split. No in-tree platforms were making use of the MMIO overloading through the machvec (nor have any of them been in some time), so we just kill all of that off. The ISA I/O routine wrapping remains unaffected, which remains the only special casing outside of the iomap API that boards need to think about. Signed-off-by: Paul Mundt <[email protected]>
