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.

MIPS: Fix GCC-4.2 'discards qualifiers from pointer target type' warnings

2009-02-22T20:15:43+00:00

Compiling dbau1x00 and gth2 boards with GCC-4.2, you would see new warnings
like this:

skuribay@ubuntu:u-boot.git$ ./MAKEALL dbau1000
Configuring for dbau1x00 board...

We're passing a volatile pointer to a function which is expecting a non-
volatile pointer.  That's potentially dangerous, so gcc warns about it.
Confirmed with ELDK 4.2 (GCC 4.2.2) and Sourcey G++ 4.2 (GCC 4.2.3).

To fix this, we add a volatile attribute to the argument in question.
The virt_to_phys function in Linux kernel also does the same thing.

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.

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.

Fixed mips_io_port_base build errors.

2007-11-17T00:37:44+00:00

This patch has been sent on:
- 29 Sep 2007

Although mips_io_port_base is currently a part of IDE command, it is quite
fundamental for MIPS I/O port access such as in[bwl] and out[bwl]. So move
it to MIPS general part, and introduce `set_io_port_base()' from Linux.

This patch is triggered by multiple definition of `mips_io_port_base' build
error on gth2 (and tb0229 also needs this fix.)

board/gth2/libgth2.a(gth2.o): In function `log_serial_char':

[PATCH v3] Add sync to ensure flash_write_cmd is fully finished

2007-02-21T15:52:31+00:00

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.
