Move architecture-specific includes to arch/$ARCH/include/asm

2010-04-13T07:13:12+00:00

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.

ppc: Use addrmap in virt_to_phys and map_physmem.

2008-12-20T00:20:08+00:00

If we have addr map support enabled use the mapping functions to
implement virt_to_phys() and map_physmem().

powerpc: fix io.h build warning with CONFIG_PHYS_64BIT

2008-12-16T15:54:41+00:00

Casting a pointer to a phys_addr_t when it's an unsigned long long
on a 32-bit system without first casting to a non-pointer type
generates a compiler warning. Fix this.

Introduce virt_to_phys()

2008-12-15T21:04:29+00:00

virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.

However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

PPC: add accessor macros to clear and set bits in one shot

PPC: add accessor macros to clear and set bits in one shot

This patch adds macros from linux/include/asm-powerpc/io.h to clear and
set bits in one shot using the in_be32, out_be32, etc. accessor functions.
They are very handy to manipulate bits it I/O registers.

This patch is required for my forthcoming FSL NAND UPM driver re-write and
the support for the TQM8548 module.

PPC: fix map_physmem build warning

2008-05-09T23:00:37+00:00

map_physmem currently generates a warning when CONFIG_PHYS_64BIT is
enabled.  This quiets the warning.

Introduce phys_size_t and move phys_addr_t into asm/types.h

2008-04-14T00:13:46+00:00

Also add CONFIG_PHYS_64BIT on powerpc to deal with 32-bit ppc's
that have larger physical addresses like 44x, 85xx, and 86xx.

Introduce map_physmem() and unmap_physmem()

2007-12-13T12:15:16+00:00

map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.

This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

Implement __raw_{read,write}[bwl] on all architectures

2007-12-13T12:15:04+00:00

This adds implementations of __raw_read[bwl] and __raw_write[bwl] to
m68k, ppc, nios and nios2. The m68k and ppc implementations were taken
from Linux.

IDE: - make ide_inb () and ide_outb () "weak", so boards can

2007-08-28T15:39:14+00:00

          define there own I/O functions.
          (Needed for the pcs440ep board).
        - The default I/O Functions are again 8 Bit accesses.
        - Added CONFIG_CMD_IDE for the pcs440ep Board.
