96c5f0816a arm: kirkwood: Change naming of dram functions from km_foo() to mvebu_foo()
Additionally the SDRAM address decoding register address is not hard coded
in the C code any more. A define is introduced for this base address.

This makes is possible to use those gpio functions from other MVEBU SoC's
as well.

22700dc6fb arm: marvell: Rework timer.c to make it usable for other MVEBU platforms
This patch does the following:
- Rename defines and registers to not use kirkwood
- Remove unused defines
- Use clrsetbits() accessor functions
- Coding style cleanup
- Clear 25MHZ bit in timer controller register init for Armada XP

There is no functional change for kirkwood. At least not intentionally.

This will be used by the upcoming Armada XP support.

8c33ba7b1d ARM: tegra: Use mem size from MC in combination with get_ram_size()
On popular request this now completes the Warren's work started for
TK1:

aeb3fcb359
ARM: tegra: Use mem size from MC rather than ODMDATA

In addition to the move of using the Tegra memory controller (MC)
register rather than ODMDATA for T20, T30 and T114 as well it further
uses the generic get_ram_size() function (see "common/memsize.c")
<supposed to be used in each and every U-Boot port>TM. Added benefit is
that it should <catch 99% of hardware related (i. e. reliably
reproducible) memory errors> as well.

Thoroughly tested on the various Toradex line of Tegra modules
available which unfortunately does not include T114 and T124 (yet at
least) plus on the Jetson TK1.

bf78b2717d arm: tegra: initial support for apalis t30
This patch adds board support for the Toradex Apalis T30 a computer on
module which can be used on different carrier boards.

For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.

The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210
  fixes hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two
  ports as host)

This patch moves mx35 to the common timer functions added in commit

  8dfafdd - Introduce common timer functions <Rob Herring>

The (removed) mx35 timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks().  get_ticks() returned a 32-bit value
cast up to a 64-bit value.  If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locks the processor.  Rather than patch the specific mx35 issues, simply
move everything over to the common code.

2fccd2d96b tegra: Convert tegra GPIO driver to use driver model
This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.

The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.

The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.

Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

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.

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.

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.

c4f80f5003 am335x_evm / gumstix pepper: Correct DDR settings
As noted by clang, we have been shifting certain values out of 32bit
range when setting some DDR registers.  Upon further inspection these
had been touching reserved fields (and having no impact).  These came in
from historical bring-up code and can be discarded.  Similarly, we had
been declaring some fields as 0 when they will be initialized that way.
Tested on Beaglebone White.

0a11d6f29c mx6: Remove duplication of iomuxc structure
There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.
