Modify the RTC API to provide one a status for the time reported by
the rtc_get() function:
0 - a reliable time is guaranteed,
< 0 - a reliable time isn't guaranteed (power fault, clock issues,
and so on).
The RTC chip drivers are responsible for providing this info if the
corresponding chip supports such functionality. If not - always
report that the time is reliable.
The POST RTC test was modified to detect the RTC faults utilizing
this new rtc_get() feature.

460EX doesn't support a fixed bootstrap option to boot from 512 byte page
NAND devices. The only bootstrap option for NAND booting is option F for
2k page devices. So to boot from a 512 bype page device, the I2C bootstrap
EEPROM needs to be programmed accordingly.
This patch adds basic NAND booting support for the AMCC Canyonlands aval
board and also adds support to the "bootstrap" command, to enable NAND
booting I2C setting.
Tested with 512 byte page NAND device (32MByte) on Canyonlands.

This patch is a rework of the 4xx interrupt handling done while
adding the 460EX/GT support. Interrupts are needed on 4xx for the
EMAC driver.

This patch changes the physical addess parameter from 32bit to 64bit.
This is needed for 36bit 4xx platforms to access areas located
beyond the 4GB border, like SoC peripherals (EBC etc.).

Every now and then a Sequoia board (or equivalent hardware) had
problems connecting to a Gigabit capable network interface.
There were differences in the PHY setup between Linux and U-Boot.
This patch fixes the problem. Apparently "remote fault" is being set,
which signals to some devices (on the other end of the cable) that a
fault has occurred, while other devices ignore it. I believe the RF bit
was causing the issue, but I removed T4 also, to match up with Linux.

The 405EZ only supports 512 bytes of rx-/tx-fifo EMAC sizes. But
currently 4k/2k is configured. This patch fixes this issue.
Thanks to Thomas Kindler <tkindler@lenord.de> for pointing this out.

Adds PCI support for MPC5121
Tested with drivers/net/rtl8139.c
Support is conditional since PCI on old silicon does not work.
ads5121_PCI_config turns on PCI
In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD

U-Boot crashes in the net loop if CONFIG_4xx_DCACHE is
enabled. To reproduce the problem ensure that 'ethrotate'
environment variable isn't set to "no" and then run
"tftp 200000 not_existent_file".
This patch tries to fix the issue.

There is no reason to icbi when invalidating the temporary stack in
the d-cache. Its impossible on e500 to have the i-cache contain
any addresses in the temp stack and it can be problematic in generating
transactions on the bus to non-valid addresses.

Commit 0db37dc... (and some others) changed the INIT_RAM TLB
mappings to be unguarded. This collided with an existing "bug"
where the mappings for the INIT_RAM were being kept around.
This meant that speculative loads to those addresses were
succeeding in the TLB, and going out to the bus, where they
were causing an exception (there's nothing at that address). The
Flash code was coincidentally causing such a speculative load.
Rather than go back to mapping the INIT RAM as guarded, we fix
it so that the entries for the INIT_RAM are invalidated. Thus
the speculative loads will fail in the TLB, and have no effect.

This is the proper fix for a missing closing brace in the function
ft_cpu_setup() noticed by joe.hamman <at> embeddedspecialties.com.
The ft_cpu_setup() function in mpc8641hpcn.c should have been
removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE,
but was missed. Only, the sbc8641d was nominally still using it.
It all got ripped out, and the funcality that was in ft_board_setup()
was refactored to remove the CPU portions into the new file
cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now.
Based loosely on an original patch from joe.hamman@embeddedspecialties.com

R29 was an unlucky choice as with recent toolchains (gcc-4.2.x) gcc
will refuse to use load/store multiple insns; instead, it issues a
list of simple load/store instructions upon function entry and exit,
resulting in bigger code size, which in turn makes the build for a
few boards fail.
Use r2 instead.

This patch enables the OneNAND boot within U-Boot.
Before this work, we used another OneNAND IPL called X-Loader based
on open source. With this work, we can build the oneboot.bin image
without other program.
The build sequence is simple.
First, it compiles the u-boot.bin
Second, it compiles OneNAND IPL
Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin
The mechanism is similar with NAND boot except it boots from itself.
Another thing is that you can only use the OneNAND IPL only to work
other bootloader such as RedBoot and so on.

The existing code assumes the SDRAM row refresh period should always
be 15.6 us. This is not always true, and indeed on the ATNGW100, the
refresh rate should really be 7.81 us.
Add a refresh_period member to struct sdram_info and initialize it
properly for both ATSTK1000 and ATNGW100. Out-of-tree boards will
panic() until the refresh_period member is updated properly.
Big thanks to Gerhard Berghofer for pointing out this issue.
