This patch removes the duplicted implementations of the pci_target_init()
function by introducing a weak default function for it. This weak default
has a different implementation for 440EP(x)/GR(x) PPC's. It can be
overridden by a board specific version (e.g. PMC440, korat).Signed-off-by: Stefan Roese

This patch introduces a weak default function for is_pci_host(),
returning 1. This is the default behaviour, since most boards only
implement PCI host functionality. This weak default can be overridden
by a board specific version if needed.Signed-off-by: Stefan Roese

All these linker scripts can be removed since the new common ppc4xx
linker script should be able to handle all of those boards.Please test and report problems. Thanks.

To avoid board-specific code accessing the mb862xx registers directly,
the public function mb862xx_probe() has been introduced. Furthermore,
the "Change of Clock Frequency" and "Set Memory I/F Mode" registers
are now defined by CONFIG_SYS_MB862xx_CCF and CONFIG_SYS_MB862xx__MMR,
respectively. The BSPs for the socrates and lwmon5 boards have been
adapted accordingly.Signed-off-by: Wolfgang Grandegger

The following changes allow U-Boot to fully relocate from flash to
RAM:
- Remove linker scripts' .fixup sections from the .text section
- Add -mrelocatable to PLATFORM_RELFLAGS for all boards
- Define CONFIG_RELOC_FIXUP_WORKS for all boardsPreviously, U-Boot would partially relocate, but statically initialized
pointers needed to be manually relocated.Signed-off-by: Peter Tyser

This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused definesPlease test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.Signed-off-by: Stefan Roese

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and ThermostatUsage:
dtt - Read temperature from digital thermometer and thermostat.After:
=> help dtt
dtt - Read temperature from Digital Thermometer and ThermostatUsage:

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.Signed-off-by: Trent Piepho

This patch fixes a problem spotted by Mikhail Zolotaryov on Sequoia with
the DDR2 configuration to only use one CS (rank). As this code is most
likely copied from the original Sequoia version, this error was copied
as well.This patch also removes some dead code.

This patch changes the return type of initdram() from long int to phys_size_t.
This is required for a couple of reasons: long int limits the amount of dram
to 2GB, and u-boot in general is moving over to phys_size_t to represent the
size of physical memory. phys_size_t is defined as an unsigned long on almost
all current platforms.This patch *only* changes the return type of the initdram function (in
include/common.h, as well as in each board's implementation of initdram). It
does not actually modify the code inside the function on any of the platforms;
platforms which wish to support more than 2GB of DRAM will need to modify
their initdram() function code.Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc

As it seems the "old" ECC initialization routine by using dflush() didn't
write all lines in the dcache back to memory on lwmon5. This could lead
to ECC error upon Linux booting. This patch changes the program_ecc()
routine to now use clean_dcache_range() instead of dflush().
clean_dcache_range() uses dcbst which is exactly what we want in this
case.Since dflush() is known is cause problems, this routine will be
removed completely and replaced by clean_dcache_range() with an
additional patch.Signed-off-by: Stefan Roese

Limit the rate of h/w watch-dog triggering on the LWMON5 board by
the CONFIG_WD_MAX_RATE value.Note that an earlier version of this patch which used microseconds
instead of ticks dis not work. The problem was that we used
usec2ticks() to convert microseconds into ticks. usec2ticks() uses
get_tbclk(), which in turn calls get_sys_info(). It turns out that
this function does a lot of prolonged operations (like divisions)
which take too much time so we do not trigger the watchdog in time,
and it resets the system.Signed-off-by: Yuri Tikhonov

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.Signed-off-by: Wolfgang Denk
