IRDA is a synonym for UARTB in tegra pinmux, remove all usage of this
synonym and replace with UARTB to disambiguate.

083bbbbe77 Tegra30: fdt: Update DT files with I2C info for T30/Cardhu
Note that T30 does not have a separate/different DVC (power I2C)
controller like T20 - all 5 I2C controllers are identical, but
DVC_I2C is still used to designate the controller intended for
power control (PWR_I2C in the schematics). On Cardhu, it's used
to access the PMU and EEPROM, as well as the audio codec, temp
sensor, and fuel gauge devices from the OS.

2f8d8d6b3a arm: Move bootstage record for board_init_f() to after arch_cpu_init()
The timer may be inited in arch_cpu_init() so it is not safe to make a
bootstage mark before this is called. Arrange the code to fix this.

Note: The question was raised as to why we don't keep all archs in sync.
PowerPC doesn't have specific bootstage markers at present (although it
does use boot progress). I hope that the generic board series will solve
this problem in general, but in the meantime this is a real problem, and
only in ARM.

We now get a correct time for board_init_f:

Timer summary in microseconds:
       Mark    Elapsed  Stage
          0          0  reset

Since the LCD is all that a typical user sees, it is useful to display
the model there.

We may be able to rearrange things some other way one day, but at
present this seems like a convenient way of getting the required
behaviour.

06fd853890 arm: Add CONFIG_DELAY_ENVIRONMENT to delay environment loading
This option delays loading of the environment until later, so that only the
default environment will be available to U-Boot.

This can address the security risk of untrusted data being used during boot.

Any time you load untrusted data you expose yourself to a bug in the
code. The attacker gets to choose the data so can sometimes carefully
craft it to exploit a bug. We try to avoid touching user-controlled
data during a verified boot unless strictly necessary. Since the
default environment is good enough in this case (or you would just
change it), this gets around the problem by just not loading the
environment.

When CONFIG_DELAY_ENVIRONMENT is defined, it is convenient to have a
run-time way of enabling loading of the environment. Add this to the
fdt as /config/delay-environment.

Note: This patch depends on http://patchwork.ozlabs.org/patch/194342/

eae78c3406 arm: Move fdt check earlier so that board_early_init_f() can use it
We want to use the fdt inside board_early_init_f(), so check for its
presence earlier in the pre-reloc init sequence.

So far ARM and microblaze are the only only ones that use
CONFIG_OF_CONTROL. Microblaze does not have the same init loop, and in
particular does not have the board_early_init_f() call. So a patch for
microblaze would have no meaning.

44df5e8d30 arm: move flush_dcache_all() to just before disable cache
In Cortex-A15 architecture, when we run cache invalidate
the cache clean operation executes automatically.
So if there are any dirty cache lines before disabling the L2 cache
these will be synchronized with the main memory when
invalidate_dcache_all() runs in the last part of U-boot

The two functions after flush_dcache_all is using the stack. So this
data will be on the cache. After disable when invalidate is called the
data will be flushed from cache to memory. This corrupts the stack in
invalida_dcache_all. So this change is required to avoid the u-boot
hang.

So flush has to be done just before clearing CR_C bit

2b16e51c2f mx6: Add workaround for ARM errata
Add workaround for the following ARM errata: 743622 and 751472.

The motivation for this change is the following kernel commit 62e4d357a
(ARM: 7609/1: disable errata work-arounds which access
secure registers), which removes the errata from multiplatform kernel.

Since imx has been converted to multiplatform in the kernel, we need to apply
such workarounds into the bootloader.

Workaround code has been taken from arch/arm/mm/proc-v7.S from 3.7.1 kernel.

Explanation of each erratum is provided at "Chip Errata for the i.MX 6Dual/6Quad"

fa5e2845a8 mxs: i2c: Implement algorithm to set up arbitrary i2c speed
This algorithm computes the values of TIMING{0,1,2} registers for the
MX28 I2C block. This algorithm was derived by using a scope, but the
result seems correct.

The resulting values programmed into the registers do not correlate
with the contents in datasheet. When using the values from the datasheet,
the I2C clock were completely wrong.

833a53c627 musb-new: am35x backend driver
Backend driver for MUSB OTG controllers found on TI AM35x.

It seems that on AM35X interrupt status registers can be updated
_before_ core registers. As we don't use true interrupts in U-Boot
and poll interrupt status registers instead this can result in
interrupt handler being called with non-updated core registers.
This confuses the code and result in hanged transfers.
Add a small delay in am35x_interrupt as a workaround.

2ffb4beb50 pmic: Introduce power_init_board() method at ./lib/board.c file
It is necessary to introduce a new system wide function- power_init_board()

It turns out, that power initialization must be done as early as possible.
In the case of PMIC framework redesign, which aims to support multiple
instances of PMIC devices the initialization shall be performed just
after malloc configuration.

The power_init_board function is a weak function with default implementation.

eef1cf2d5c include/linux/byteorder: import latest endian definitions from linux
u-boot's byteorder headers did not contain endianness attributions
for use with sparse, causing a lot of false positives.  Import the
kernel's latest definitions, and enable them by including compiler.h
and types.h.  They come with 'const' added for some swab functions, so
fix those up, too:

include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default]

Also, note: u-boot's historic __BYTE_ORDER definition has been
preserved (for the time being at least).

We also remove ad-hoc barrier() definitions, since we're including
compiler.h in files that hadn't in the past:

macb.c:54:0: warning: "barrier" redefined [enabled by default]

In addition, including compiler.h in byteorder changes the 'noinline'
definition to expand to __attribute__((noinline)).  This fixes
arch/powerpc/lib/bootm.c:

bootm.c:329:16: error: attribute '__attribute__': unknown attribute
bootm.c:329:16: error: expected ')' before '__attribute__'
bootm.c:329:25: error: expected identifier or '(' before ')' token

powerpc sparse builds yield:

include/common.h:356:22: error: marked inline, but without a definition

the unknown-reason inlining without a definition is considered obsolete
given it was part of the 2002 initial commit, and no arm version was
'fixed.'

also fixed:
ydirectenv.h:60:0: warning: "inline" redefined [enabled by default]

2b7818d49f ARM: enhance u-boot.lds to detect over-sized SPL
Add an ASSERT() to u-boot.lds to detect an SPL that doesn't fit within
SPL_TEXT_BASE..SPL_MAX_SIZE.

Different .lds files implement this check in two possible ways:
1) An ASSERT() like this
2) Defining a MEMORY region of size SPL_MAX_SIZE, and re-directing all
   linker output into that region. Since u-boot.lds is used for both
   SPL and main U-Boot, this would entail only sometimes defining a
   MEMORY region, and only sometimes performing that redirection, and
   hence option (1) was deemed much simpler, and hence implemented.

Note that this causes build failures at least for NVIDIA Tegra Seaboard
and Ventana. However, these are legitimate; the SPL doesn't fit within
the required space, and this does cause runtime issues.

When -ffunction-sections or -fdata-section are used, symbols are placed
into sections such as .data.eserial1_device and .bss.serial_current.
Update the linker script to explicitly include these. Without this
change (at least with my gcc-4.5.3 built using crosstool-ng), I see that
the sections do end up being included, but __bss_end__ gets set to the
same value as __bss_start.

d81b27a245 MX35: add support for woodburn board
The woodburn board is based on the MX35 SOC.
Support for both external (NOR) and internal
(SD Card) boot mode are added. It uses the
generic SPL framework to implement the internal boot
mode.

The following peripherals are supported:
- Ethernet (FEC)
- SD Card
- NAND (512 MB)
- NOR Flash

In the internal boot mode, a simple imximage header
is generated to set the address in internal RAM
where the SOC must copy the SPL code. The initial setup
is then demanded to the SPL itself.
