9f15bc0c1c i2c:gpio:s5p: I2C GPIO Software implementation (via soft_i2c)
This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

9db1bfa110 ARM: MX51: PLL errata workaround
This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

ef5d9eb925 gpio:samsung s5p_ suffix add for GPIO functions
This change is driven by need of general gpio_* functions,
which as their parameter are accepting the GPIO pin number, NOT
block and pin.

This makes the code alike to omap, and allows for using more
generic frameworks (e.g. software I2C).

and the driver will automatically calculate the register values.

d2f18c275e omap4: utility function to identify the context of hw init
The basic hardware init of OMAP4(s_init()) can happen in 4
different contexts:
 1. SPL running from SRAM
 2. U-Boot running from FLASH
 3. Non-XIP U-Boot loaded to SDRAM by SPL
 4. Non-XIP U-Boot loaded to SDRAM by ROM code using the
    Configuration Header feature

What level of hw initialization gets done depends on this
context. Add a utility function to find this context.

2c451f7831 armv7: cache maintenance operations for armv7
- Add a framework for layered cache maintenance
	- separate out SOC specific outer cache maintenance from
	  maintenance of caches known to CPU

- Add generic ARMv7 cache maintenance operations that affect all
  caches known to ARMv7 CPUs. For instance in Cortex-A8 these
  opertions will affect both L1 and L2 caches. In Cortex-A9
  these will affect only L1 cache

- D-cache operations supported:
	- Invalidate entire D-cache
	- Invalidate D-cache range
	- Flush(clean & invalidate) entire D-cache
	- Flush D-cache range
- I-cache operations supported:
	- Invalidate entire I-cache

- Add maintenance functions for TLB, branch predictor array etc.

- Enable -march=armv7-a so that armv7 assembly instructions can be
  used

29d53d19f3 Kirkwood: allow to override CONFIG_SYS_TCLK
This patch allow to override CONFIG_SYS_TCLK from board configuration
files. This is needed for the Network Space v2 which use a non standard
core clock frequency (166MHz instead of 200MHz for a 6281 SoC).

As a possible enhancement for 6281 and 6282 devices, TCLK could be
dynamically detected by checking the Sample at Reset register bit 21.

Additionally this patch fix a typo.

8627111543 IMX: MX31: Cleanup include files and drop nasty #ifdef in drivers
As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

2cf36ae7cf MX31: add support for MX31 watchdog
The patch add CONFIG_HW_WATCHDOG to be used
with the internal watchdog timer of the MX31
processor. Two function are exported for the
board maintainers:
	mxc_hw_watchdog_enable
	mxc_hw_watchdog_reset

The board maintainer can decide to use mxc_hw_watchdog_reset as
hw_watchdog_reset, or to implement his own function to reset
the watchdog.
The watchdog timer can be configured with CONFIG_SYS_WD_TIMER_SECS
(value in seconds). The MX31 allows values between 0.5
(CONFIG_SYS_WD_TIMER_SECS = 0) and 128 seconds.

495df3bad9 ARM: fix write*() I/O accessors
Commit 3c0659b "ARM: Avoid compiler optimization for readb, writeb
and friends." introduced I/O accessors with memory barriers.
Unfortunately the new write*() accessors introduced a bug:

The problem is that the argument "v" gets evaluated twice.  This
breaks code like used here (from "drivers/net/dnet.c"):

	for (i = 0; i < wrsz; i++)
		writel(*bufp++, &dnet->regs->TX_DATA_FIFO);

Use auxiliary variables to avoid such problems.

3c0659b535 ARM: Avoid compiler optimization for readb, writeb and friends.
gcc 4.5.1 seems to ignore (at least some) volatile definitions,
avoid that as done in the kernel.

Reading C99 6.7.3 8 and the comment 114) there, I think it is a bug of that
gcc version to ignore the volatile type qualifier used e.g. in __arch_getl().
Anyway, using a definition as in the kernel headers avoids such optimizations when
gcc 4.5.1 is used.

Maybe the headers as used in the current linux-kernel should be used,
but to avoid large changes, I've just added a small change to the current headers.

d26074012b da850: Add RMII support for EMAC
This patch is a port of the work by Sudhakar Rajeshekhara in commit
ab3effbcad8851cc65dc5241a01c064d2030a3b2 of
git://arago-project.org/git/people/sandeep/u-boot-davinci.git.

The da850 UI board has on it an RMII PHY which can be used if the MDC line
to the MII PHY on the baseboard is disabled and the RMII PHY is enabled by
configuring the values of some GPIO pins on the IO expander of the UI board.
This patch implements disabling that line via GPIO2[6], configuring the UI
board's IO expander and setting only the pinmux settings that are needed for
RMII operation.

Tested on da850evm by adding a define for CONFIG_DRIVER_TI_EMAC_USE_RMII.

48571ff005 Add board support for hawkboard
The patch adds basic board support for TI's OMAP-L138 based
Hawkboard. This board is pretty similar to the da850 EVM. Support for
nand and network access is added in this version.

The following bootup procedure is used.

At reset, the Rom Boot Loader(RBL), initialises the ddr and the nand
controllers and copies the second stage bootloader(nand_spl) to
RAM. The secondary bootloader then copies u-boot from a predefined
location in the nand flash to the RAM, and passes control to the
u-boot image.

Three config options are supported
* hawkboard_config - Used to create the u-boot.bin. Tftp the
 u-boot.bin image to the RAM from u-boot, and flash to the nand flash
 at address 0xe0000.

* hawkboard_nand_config - Used to generate the secondary
 bootloader(nand_spl) image. This creates an elf file u-boot-spl
 under nand_spl/. Create an AIS signed image using this file, and
 flash it to the nand flash at address 0x20000. The ais file should
 fit in one block.

* hawkboard_uart_config - This is same as the first image, but with
 the TEXT_BASE as expected by the RBL(0xc1080000). Create the AIS

a9aa392629 Drop support for CONFIG_SYS_ARM_WITHOUT_RELOC
When this define was introduced, the idea was to provide a soft
migration path for ARM boards to get adapted to the new relocation
support.  However, other recent changes led to a different
implementation (ELF relocation), where this no longer works.  By now
CONFIG_SYS_ARM_WITHOUT_RELOC does not only not help any more, but it
actually hurts because it obfuscates the actual code by sprinkling it
with lots of dead and non-working debris.

So let's make a clean cut and drop CONFIG_SYS_ARM_WITHOUT_RELOC.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

575001e40c MX51: Add IPU driver for video support
The patch is a porting of the IPU Linux driver
developed by Freescale to have framebuffer
functionalities in u-boot. The port is based on
kernel 2.6.31 commit cc4fe714041805997b601fe8e5dd585d8a99297f,
as delivered by Freescale [i.MX BSP].
Most features are dropped from the original driver and
only LCD support is the goal of this porting.

80124df14f PXA: fix MDREFR[APD] bit setting
pxa_mem_setup macro use r6 to store CONFIG_SYS_MDREFR_VAL during memory
initialization. This reg is modified during execution of pxa_wait_ticks.
Later we use r6 to setup MDREFR[APD] bit. As result MDREFR[APD] is always
zero.

de941241a0 ARMV7: OMAP: Add new mmc driver compatible with CONFIG_GENERIC_MMC
OMAP boards currently use a legacy mmc driver. This patch adds a new
mmc driver which will work with the generic mmc driver in u-boot.

This new driver will work with both OMAP3 and OMAP4 boards.

This patch does not remove the old driver.  It should remain in the
tree until all boards that use it switch to the new driver.

b80e41ac54 ARMV7: Versatile Express Coretile CortexA9x4 support
Adds support for the ARM quad-core Cortex-A9 processor

This system includes a motherboard(Versatile Express), daughterboard
(Coretile), and SOC(Cortex-A9 quad core).  The serial port, ethernet,
and flash systems work with these additions.  The naming convention
is:
   SOC -> CortexA9 quad core = ca9x4
   daughterboard -> Coretile = ct
   motherboard -> Versatile Express = vxp
This gives ca9x4_ct_vxp.c as the board support file.

7b37a27e14 davinci_emac: davinci_eth_set_mac_addr to ->write_hwaddr
This patch proposes to migrate the davinci_emac driver to using the
eth_device->write_hwaddr function pointer as suggested by Ben Warren.

All the davinci boards had the behaviour, prior to this patch, of
sync'ing the environment variable enetaddr with the MAC address read
from non-volatile storage on boot -- when the two locations disagreed,
the environment variable value took precendence. This patch keeps the
same behaviour but lets eth_initialize take care of it.

This patch refactors davinci_emac setup in the boards so that the MAC
address is read from non-volatile storage into the environment variable
and then the environment variable value is use in eth_intialize. The
only exception is the direct call to davinci_eth_set_mac_addr made by
the da830evm board init which was changed into an assignment of the
enetaddr field.
