* x86: Allow I/O functions to use pointersSimon Glass2016-03-171-2/+10
| | | | | | | | | | | | | | | | | | | | | It is common with memory-mapped I/O to use the address of a structure member to access memory, as in: struct some_regs { u32 ctrl; u32 data; } struct some_regs *regs = (struct some_regs *)BASE_ADDRESS; writel(1, &reg->ctrl); writel(2, &reg->data); This does not currently work with inl(), outl(), etc. Add a cast to permit this.

* x86: Add macros to clear and set I/O bitsSimon Glass2016-03-171-0/+22
| | | | | | | | | | The clrsetbits_...() macros are useful for working with memory mapped I/O. But they do not work with I/O space, as used on x86 machines. Add some macros to provide similar features for I/O. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* Replace <compiler.h> with <linux/compiler.h>Masahiro Yamada2014-12-081-1/+1
| | | | | | Including <linux/compiler.h> is enough for general use. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* x86: Add clr/setbits functionsSimon Glass2014-11-211-0/+49
| | | | | | These are available on other architectures. Make them available on x86 also. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Increase the size of the phys_size_t and phys_addr_t typesGabe Black2012-12-061-2/+4
| | | | | | | | | These types should be 64 bits long to reflect the fact that physical addresses and the size of physical areas of memory are more than 32 bits long. Signed-off-by: Gabe Black <gabeblack@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Don't spam POST80 codes with slow IO functionsStefan Reinauer2012-11-301-1/+1
| | | | | | | | | | | | | | This patch prevents u-boot from "spamming" random progress codes on a port 80 "post card". The previous version of this patch just removed the delays in the "slow" IO functions, as they do not need to be slow, however, this patch is less intrusive. It uses another unused port that is often used by BIOSes (and the Linux Kernel) for small delay timing purposes.

* x86: Include types.h explicitly in the i386 version of io.hGabe Black2012-11-301-0/+2
| | | | | | | | | | The i386 version of io.h depends on the phys_addr_t type which is defined in types.h. It wasn't including that explicitly, and was working presumably because the other files including it had already included types.h themselves directly or indirectly. This change fixes that.
