3c927cccdc fdt: check for fdt errors in fdt_create_phandle
fdt_create_phandle() was ignoring errors from fdt_set_phandle().  If an
error occurs, print an error message and return 0, which is an invalid
phandle.  We also need to change the return type for fdt_create_phandle()
to indicate that it cannot return an error code.

8ddb10eae0 fdt: Add a do_fixup_by_path_string() function
The do_fixup_by_path_string() will set the specified node's property to the
value contained in "status". It would just be an inline wrapper for
do_fixup_by_path() that calls strlen on the argument.

e140aad18a powerpc/85xx: Drop CONFIG_VIDEO on P1_P2_RDB-PC boards to reduce size
With older compilers (gcc-4.2.x) we run into issues that resulting image
is too large.  We can save a bunch of space by removing the video support.
In general video support on these boards is a nice to have since it
requires a PCIe add-on card.

62a22dca32 video: Moving mx3fb.c to CONFIG_VIDEO
mx3fb.c was based on CONFIG_LCD and is moved by this patch to
CONFIG_VIDEO, which has greater freedom in selecting videomodes
even at runtime.

This renders the accumulating list of display defines
(CONFIG_DISPLAY_VBEST..., CONFIG_DISPLAY_C057...) obsolete as
these may be setup through env variables:

uboot> setenv mydisplay 'video=ctfb240,y:320,depth:16,mode:0,pclk:185925,
	le:9,ri:17,up:7,lo:10,hs:1,vs:1,sync:100663296,vmode:0'
uboot> setenv videomode ${mydisplay}

This commit also fixes the board config files for qong and
imx31_phycore boards as needed. The videomode settings of
previously supported displays are added to CONFIG_EXTRA_ENV_SETTINGS
now. CONFIG_SYS_MALLOC_LEN for imx31_phycore board is increased
to make the frame buffer allocation working with the changed
driver.

e9934f0b60 VIDEO: MX5: Switch MX5 to CONFIG_VIDEO
The framebuffer driver for MX5 is based on CONFIG_LCD.
In the current implementation, there is a serious bug
because the required memory is allocated before
relocation, but the driver knows only later which is
the resolution of the display. The patch switches the driver
to CONFIG_VIDEO and the memory is allocated by the driver itself.

We also need to switch the vision2 board code and config file
in the same commit so that this commit will be bisectable.

from Qi hardware:

http://en.qi-hardware.com/wiki/Ben_NanoNote
http://en.qi-hardware.com/wiki/Main_Page
http://en.wikipedia.org/wiki/Qi_hardware

This Jz4740-based clamshell device does not use NOR flash to boot.
The initial bring-up assumes that U-Boot is directly loaded into SDRAM
using USB boot tool, and starts from 0x80100000.

About USB boot tool
-------------------

Jz4740 is one of the XBurst processors with USB boot functionality
supported.  The CPU can boot from a small ROM in the LSI, initialize
CPU and USB module, then wait for USB commands from the USB host.
We can send 8 KB binary data to the CPU cache using USB boot tool.

USB boot tool is available to the public at Ingenic website.  Also
there is an alternative Debian package named xburst-tools.

d63894654d UBI: init eba tables before wl when attaching a device
This fixes that u-boot gets stuck when a bitflip was detected
during "ubi part <ubi_device>". If a bitflip was detected UBI tries
to copy the PEB to a different place. This needs that the eba table
are initialized, but this was done after the wear levelling worker
detects the bitflip. So changes the initialisation of these two
tasks in u-boot.

This is a u-boot specific patch and not needed in the linux layer,
because due to commit 1b1f9a9d00
UBI: Ensure that "background thread" operations are really executed
we schedule these tasks in place and not as in linux after the inital
task which schedule this new task is finished.

6016194371 NAND: davinci: choose correct 1-bit h/w ECC reg
In nand_davinci_readecc(), select the correct NANDF<n>ECC register based
on CONFIG_SYS_NAND_CS rather than hardcoding the choice of NANDF1ECC.
This allows 1-bit hardware ECC to work with chip select other than CS2.

Note this now matches the usage in nand_davinci_enable_hwecc(), which
already had the correct handling, and allows refactoring to a single
function encapsulating the register read.

Without this fix, writing NAND pages to a chip not wired to CS2 would
result in in the ECC calculation always returning FFFFFF for each
512-byte segment, and reading back a correctly written page (one with
ECC intact) would always fail. With this fix, the ECC is written and
verified correctly.

80421fcc3e MIPS: Ingenic XBurst Jz4740 processor support
Jz4740 is a multimedia application processor targeting for mobile
devices like e-Dictionary, eBook, portable media player (PMP) and
GPS navigator.  Jz4740 is powered by Ingenic 360 MHz XBurst CPU core
(JzRISC), in which RISC/SIMD/DSP hybrid instruction set architecture
provides high integration, high performance and low power consumption.

JzRISC incorporated in Jz4740 is the advanced and power-efficient
32-bit RISC core, compatible with MIPS32, with 16K I-Cache and 16K
D-Cache, and can operate at speeds up to 400 MHz.

On-chip modules such as LCD controller, embedded audio codec, multi-
channel SAR-ADC, AC97/I2S controller and camera I/F offer a rich
suite of peripherals for multimedia application.  NAND controller
(SLC/MLC), USB (host 1.1 and device 2.0), UART, I2C, SPI, etc. are
also available.

For more info about Ingenic XBurst Jz4740:
  http://en.ingenic.cn/eng/
  http://www.linux-mips.org/wiki/Ingenic

This patch introduces XBurst CPU support in U-Boot.  It's compatible
with MIPS32, but requires a bit different cache maintenance, timer
routines, and boot mechanism using USB boot tool, so XBurst support
can go into a separate new home, cpu/xburst/.

We really shouldn't be overwriting bat registers with translation enabled,
especially when we're executing code using one of them for translating
the current instruction stream.  Instead, disable address translation
while doing the final BAT setup.

In order to do this, setup_bats has to move back to asm code, because we
require translation to be enabled to have a stack for C code.  The yucky
thing about that is that the assembler doesn't like ULL so we have to
switch to using HIGH/LOW pairs for physical addresses that are > 32 bits
in length.

3038171628 powerpc/85xx: fix null pointer dereference when init the SGMII TBI PHY
Function dtsec_configure_serdes() needs to know where the TBI PHY registers
are in order to configure SGMII for proper SerDes operation.

During SGMII initialzation, fm_eth_init_mac() passing NULL for 'phyregs'
when it called init_dtsec(), because it was believed that phyregs was not
used.  In fact, it is used by dtsec_configure_serdes() to configure the TBI
PHY registers.

We also need to define the PHY registers in struct fm_mdio.

712cf7ab0b powerpc/mpc8xxx: Merge entries in DDR speed table
It is not necessary to keep multiple entries for the same setting in DDR
speed tables. Merge them for smaller tables. Also restructure the tables
for smaller size. Cleanup some typedefs.

Enforce strict checking for speed table. If DIMM is running at higher than
known speed, try to use the highest speed setting. If rank is unknown, it
has to panic.

Removed ODT overriding for P2020DS as it is not necessary.

ebfdacb42b phylib: Work around bug in Teranetics PHY
The Teranetics PHY does not properly report the link state
for fiber connections. The new PHY code actually checked the link,
and so the FM driver would refuse to talk over a linkless PHY.

But the link may actually be up, so now we always report it as up
for fiber connections on the tn2020.

babb348cd0 powerpc/85xx: CONFIG_ENABLE_36BIT_PHYS does not depend on CONFIG_PHYS_64BIT
The macro CONFIG_ENABLE_36BIT_PHYS is used to indicate that the given SOC is
capable of 36-bit physical addresses, even if such large addresses are not
used.  On two boards, this macro was enabled only when building a 36-bit
image.

6f5e1dc531 powerpc/8xxx: Add support for interactive DDR programming interface
Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.
