7b4bd121b6 EXYNOS: Add dummy definition to fix compilation dependency on CONFIG_EXYNOS_MIPI_DSIM
When only DP is used, we need not enable CONFIG_EXYNOS_MIPI_DSIM.
But if we do not select CONFIG_EXYNOS_MIPI_DSIM, exynos_fb.c throws
error saying exynos_mipi_dsi_init() not defined. So, we add
dummy definition for exynos_mipi_dsi_init when CONFIG_EXYNOS_MIPI_DSIM
is not defined.

3e75e69668 arch-kirkwood: Ethernet port macro returning incorrect address
Modified the arch-kirkwood header so KWGBE_PORT_SERIAL_CONTROL1_REG(x)
returns the correct address.

Originally calling KWGBE_PORT_SERIAL_CONTROL1_REG(1) returned the
address for port 0 and vice versa.

Doesn't have any knock on effects to the u-boot code as the only
time they're used is to do the same function to both addresses

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.

The i.MX23 has different register layout and bit placement in the

add ifdef around inclusion of regs-*-mx28.h in imx-regs.h so the

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.

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.

000820b583 am335x: Enable RTC 32K OSC clock
In order to support low power state, you must source kernel system
timers to persistent clock, available across suspend/resume.  In case of
AM335x device, the only source we have is, RTC32K, available in
wakeup/always-on domain.  Having said that, during validation it has
been observed that, RTC clock need couple of seconds delay to stabilize
the RTC OSC clock; and such a huge delay is not acceptable in kernel
especially during early init and also it will impact quick/fast boot
use-cases.

So, RTC32k OSC enable dependency has been shifted to
SPL/first-bootloader.

782b028841 mx5: lowlevel_init.S: Fix PLL settings for mx53
Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz.

Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz
instead.

Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI
at 1080p because the IPU clock cannot reach the requested frequency.

Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its
maximum frequency.

Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little
bit to allow easier comparison with the original clock setup from FSL U-boot.

The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h.
Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs
that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20'

7ac2fe2da2 OMAP: networking support for SPL
This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.

In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer,
clear the BSS and call board_init_r.  We mark this as weak as some
platforms may need to perform additional initalization at this point.
We provide a gd that we know will be in a usable location, once the BSS
has been cleared to help with this as well.  Finally, we no longer call
relocate_code so remove that from the armv7 version.

Next, both board_init_f and jump_to_image_linux are going to be
inherently arch-specific, so move these versions to arch/arm/lib/spl.c

8203b201ea kw_spi: fix clock prescaler computation
The computation was not correct with low clock values: setting a 1MHz

clock.

This patch implements a correct computation method according to the

The contained pad settings are the minimum required to make an Efika MX boot

It is recommended that this file not be just a dumping ground for pins but
only contain the settings required for all the boards using it.

For more details, see:
http://www.broadcom.com/products/BCM2835
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf.

Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.

6995a28937 am33xx evm: Update secure_emif_sdram_config during ddr init
This patch updates secure_emif_sdram_config with the
same value written to sdram_config during ddr3 initialization.

During suspend/resume, this value is copied into sdram_config.
With this, a write to sdram_config at the end of resume sequence
which triggers an init sequence can be avoided.

Without this register write in place, the DDR_RESET line goes
low for a few cycles during resume which is a violation of the
JEDEC spec.

41aebf8106 omap4/5/am33xx: Make lowlevel_init available to all armv7 platforms
Make the lowlevel_init function that these platforms have which just
sets up the stack and calls a C function available to all armv7
platforms.  As part of this we change some of the macros that are used
to be more clear.  Previously (except for am335x evm) we had been
setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are
equivalent to simply referencing NON_SECURE_SRAM_END.  On am335x evm we
should have been doing this initially and do now.

a74f0c7cb5 am33xx: Correct and clean up ddr_regs struct
The ddr_regs struct was incorrectly offset after the dt0wiratio0 entry.
Correct this by documenting a missing register that will be used at some
point in the future (when write leveling is supported).  Further, the
cmdNcs{force,delay} fields are undocumented and we have been setting
them to zero, remove.  Next, setting of the
'DATAn_REG_PHY_USE_RANK0_DELAYS field belongs with the rest of the
ddr_data entries, so program it there.  Finally, comment on how we are
configuring the DATA1 registers that correspond to the DATA0 (dt0)
registers defined in the struct.

7d8a961d31 am335x: ddr_defs: Update EMIF parameters
EMIF parameters are calculated based on the AC timing
parameters from the SDRAM datasheet and the DDR frequency.

Current values for these paramters in AM335x U-Boot code,
though reliable, are not fully optimal. The most optimal
settings can be derived based on the guidelines published
at [1]. A pre-computed set of values with the most optimum
settings for AM335x EVM and BeagleBone can be found at [2].
