398415114f 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.

f3612a7b19 PPC: fix map_physmem build warning
map_physmem currently generates a warning when CONFIG_PHYS_64BIT is
enabled.  This quiets the warning.

e99ccb4881 Introduce phys_size_t and move phys_addr_t into asm/types.h
Also add CONFIG_PHYS_64BIT on powerpc to deal with 32-bit ppc's
that have larger physical addresses like 44x, 85xx, and 86xx.

4d7d6936eb Introduce map_physmem() and unmap_physmem()
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.

812711ce6b Implement __raw_{read,write}[bwl] on all architectures
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.

f98984cb19 IDE: - make ide_inb () and ide_outb () "weak", so boards can
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.

3a197b2fe4 [PATCH v3] Add sync to ensure flash_write_cmd is fully finished
Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.

8bde7f776c * Code cleanup:
- remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)
