c65a2abb6c ARM: make gd a function for clang
"clang does not support global register variables; this is
unlikely to be implemented soon because it requires additional
LLVM backend support" [1]

Workaround it by obtaining the value of gd/r9 by an inline
asm routine. Note there is no set routine added for ARM at the
moment, since most if not all updates of gd from c are actually
not needed for ARM.

Introducing the function exynos_lcd_early_init() would take care of this

9352697aa0 board/ti/dra7xx: add support for parallel NOR
This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM.
The Flash device is connected to GPMC controller on chip-select[0] and accessed
as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and
is CFI compatible.

As multiple devices are share GPMC pins on this board, so following board
settings are required to detect NOR device:
     SW5.1 (NAND_BOOTn) = OFF (logic-1)
     SW5.2 (NOR_BOOTn)  = ON  (logic-0) /* Active-low */
     SW5.3 (eMMC_BOOTn) = OFF (logic-1)
     SW5.4 (QSPI_BOOTn) = OFF (logic-1)

And also set appropriate SYSBOOT configurations:
     SW3.1 (SYSBOOT[ 8])= ON  (logic-1) /* selects SYS_CLK1 speed */
     SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */
     SW3.3 (SYSBOOT[10])= ON  (logic-1) /* wait-pin monitoring = enabled */
     SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */
     SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */

d755a5fb20 sunxi: dram: Configurable DQS gating window mode and delay
The hardware DQS gate training is a bit unreliable and does not
always find the best delay settings.

So we introduce a 32-bit 'dqs_gating_delay' variable, where each
byte encodes the DQS gating delay for each byte lane. The delay
granularity is 1/4 cycle.

Also we allow to enable the active DQS gating window mode, which
works better than the passive mode in practice. The DDR3 spec
says that there is a 0.9 cycles preamble and 0.3 cycle postamble.
The DQS window has to be opened during preamble and closed during
postamble. In the passive window mode, the gating window is opened
and closed by just using the gating delay settings. And because
of the 1/4 cycle delay granularity, accurately hitting the 0.3
cycle long postamble is a bit tough. In the active window mode,
the gating window is auto-closing with the help of monitoring
the DQS line, which relaxes the gating delay accuracy requirements.

But the hardware DQS gate training is still performed in the passive
window mode. It is a more strict test, which is reducing the results
variance compared to the training with active window mode.

1a9717cbb3 sunxi: dram: Configurable MBUS clock speed (use PLL5 or PLL6)
The sun5i hardware (Allwinner A13) introduced configurable MBUS clock
speed. Allwinner A13 uses only 16-bit data bus width to connect the
external DRAM, which is halved compared to the 32-bit data bus of sun4i
(Allwinner A10), so it does not make much sense to clock a wider
internal bus at a very high speed. The Allwinner A13 manual specifies
300 MHz MBUS clock speed limit and 533 MHz DRAM clock speed limit. Newer
sun7i hardware (Allwinner A20) has a full width 32-bit external memory
interface again, but still keeps the MBUS clock speed configurable.
Clocking MBUS too low inhibits memory performance and one has to find
the optimal MBUS/DRAM clock speed ratio, which may depend on many
factors:
    http://linux-sunxi.org/A10_DRAM_Controller_Performance

This patch introduces a new 'mbus_clock' parameter for the 'dram_para'
struct and uses it as a desired MBUS clock speed target. If 'mbus_clock'
is not set, 300 MHz is used by default to match the older hardcoded
settings.

PLL5P and PLL6 are both evaluated as possible clock sources. Preferring
the one, which can provide higher clock frequency that is lower or
equal to the 'mbus_clock' target. In the case of a tie, PLL5P has
higher priority.

Attempting to set the MBUS clock speed has no effect on sun4i, but does
no harm either.

5c18384dea sunxi: dram: Re-introduce the impedance calibration ond ODT
The DRAM controller allows to configure impedance either by using the
calibration against an external high precision 240 ohm resistor, or
by skipping the calibration and loading pre-defined data. The DRAM
controller register guide is available here:

    http://linux-sunxi.org/A10_DRAM_Controller_Register_Guide#SDR_ZQCR0

The new code supports both of the impedance configuration modes:
   - If the higher bits of the 'zq' parameter in the 'dram_para' struct
     are zero, then the lowest 8 bits are used as the ZPROG value, where
     two divisors encoded in lower and higher 4 bits. One divisor is
     used for calibrating the termination impedance, and another is used
     for the output impedance.
   - If bits 27:8 in the 'zq' parameters are non-zero, then they are
     used as the pre-defined ZDATA value instead of performing the ZQ
     calibration.

Two lowest bits in the 'odt_en' parameter enable ODT for the DQ and DQS
lines individually. Enabling ODT for both DQ and DQS means that the
'odt_en' parameter needs to be set to 3.

aae2aef9c8 arm: Set up global data before board_init_f()
At present arm defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that
the global_data pointer is set up in board_init_f(). However it is
actually set up before this, it just isn't zeroed.

If we zero the global data before calling board_init_f() then we
don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA.

Make this change (on arm32 only) to simplify the init process. I
don't have the ability to test aarch64 yet.

a6e50a88d8 ahci: provide sunxi SATA driver using AHCI platform framework
This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms
with sata included.

The PHY setup is derived from the Alwinner releases and Linux, but is mostly
undocumented.

The Allwinner AHCI controller also requires some magic (and, again,
undocumented) DMA initialisation when starting a port.  This is added under a
suitable ifdef.

This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on
contents of Linux DTS files, including SATA power pin config taken from the
DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

f510aeae68 ARM: HYP/non-sec: allow relocation to secure RAM
The current non-sec switching code suffers from one major issue:
it cannot run in secure RAM, as a large part of u-boot still needs
to be run while we're switched to non-secure.

This patch reworks the whole HYP/non-secure strategy by:
- making sure the secure code is the *last* thing u-boot executes
  before entering the payload
- performing an exception return from secure mode directly into
  the payload
- allowing the code to be dynamically relocated to secure RAM
  before switching to non-secure.

This involves quite a bit of horrible code, specially as u-boot
relocation is quite primitive.

Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and

in places where they're used. Align lines and remove redundant
definitions in kardware-k2hk.h at the same time.

Using common KS2_ prefix helps resolve redundant redefinitions and
adds opportunity to use KS2_ definition across a project not thinking about
what SoC should be used. It's more convenient and we don't need to worry
about the SoC type in common files, hardware.h will think about that.
The hardware.h decides definitions of what SoC to use.

5ba95541b7 usb: phy: omap_usb_phy: implement usb_phy_power() for AM437x
Newer AM437x silicon requires us to explicitly power up
the USB2 PHY. By implementing usb_phy_power() we can
achieve that.

2c95211167 am43xx: Update EMIF DDR3 Configuration for AM43x GP
* Boot failures have been discovered due to a combination of routing issues and
  non optimal ddr3 timings in the EMIF
* Since ddr3 timings are different after significant board layout changes
  different timings are required for alpha, beta and production boards.
