6c739c5d8a sunxi: Complete i2c support for each supported platform
Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms
even have up to 5. This adds support for every controller on each supported
platform, which is especially useful when using expansion ports on single-board-
computers.

8deacca975 sunxi: Complete mmc pin mux for each supported platform, configured with Kconfig
Sunxi platforms have different possible mmc pin mux setups (except for mmc0),
which are different across platforms.

This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig
options. This is especially relevant when a second (in addition to mmc0) port
is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

ebd468b2d2 sunxi: common VBUS detection logic in usbc
VBUS detection could be needed not only by the musb code (to prevent host mode),
but also by e.g. gadget drivers to start only when a cable is connected.

In addition, this allows more flexibility in vbus detection, as it could easily
be extended to other USBC indexes. Eventually, this would help making musb
support independent from a hardcoded USB controller index (0).

this removes the sunxi specific CONFIG_CLK_FULL_SPEED defined in each

52defe8f65 sunxi: musb: Check Vbus-det before enabling otg port power
Sending out 5V when there is a charger connected to the otg port is not a
good idea, so check for this and error out.

Note this commit currently breaks otg support on the q8h tablets, as we need
to do some magic with the pmic there to get vbus info, this is deliberate
(better safe then sorry), fixing this is on my TODO list.

d133647af4 sunxi: dram: Optionally use standard JEDEC timings for sun[457]i
In addition to the current Android magic settings, allow to optionally use
DDR3 timing parameters, which are tailored for different clock frequencies
and JEDEC speed bins. This should improve reliability and performance.

Adding '+S:CONFIG_DRAM_TIMINGS_DDR3_1066F_1333H=y' to the board defconfig
allows to use timings, which are calculated for the DDR3-1066F speed bin.
A lot of DDR3 chips, which are used in real Allwinner based devices,
support DDR3-1066F speed bin timings.

And adding '+S:CONFIG_DRAM_TIMINGS_DDR3_800E_1066G_1333J=y' should work
with any DDR3 chips, because this targets the slowest JEDEC speed bins.

The vendor magic values are still used by default for DRAM, but board
maintainers now have more flexibility in DRAM timings selection.

fb75d972ea sunxi: video: Force h/vsync active high when using ext. vga dac on some boards
On both my A13-OLinuxIno and my A13-OLinuxIno-Micro, the vga output gives an
unstable image when active low v or hsync is used.

The problem seems to be specific to the OLinuxIno A13 (normal & micro)
boards. I've just looked up the schematics and they use an opendrain driver
for the vga sync lines, and with sync pulses it is the logical high->low
edge of the pulse which counts for the timing, which with an active low
sync is being driven by the pull-up, and that simply seems to not drive
it hard enough to get a stable image.

So force v and hsync active high on these boards. independent of what the
modeline says. This fixes the unstable image.

56333be9b2 sunxi: Drop qt840a_defconfig
The qt840a is one of the many tv-boxes using the "i12" A20 pcb, but it
populates only one of the 2 places for a 16 bit dram ic, thus reducing
the buswidth to 16 bits, and the amount of ram to 512M, which is why we
had a separate config for it.

This commit switches the generic i12-tvbox_defconfig over to DRAM
autoconfiguration, so that it will work with the qt840a too, and drops the
qt840a specific config, like we've done with other memory-amount specific
configs before.

Tested on a generic i12-tvbox with 32 bit bus-width / 1G RAM, and on a
qt840a with 16 bit bus-width / 512M RAM.

8ffc487c75 sunxi: Stop differentiating between 512M and 1G variants of the same board
While working on adding more boards I noticed that we lack a config for
the 512M cubieboard, and that some of the new boards which I want to add also
have 512M and 1G variants, rather then adding 2 defconfig's for all of these,
lets switch the exising boards which have both a 512M and 1024M variant over
to the sun4i dram autoconfig code.

This also drops the foo_RAMSIZE_defconfig variants of boards where we currently
have 2 separate configs already.

Note:
1) The newly introduced CONFIG_DRAM_EMR1 kconfig value is not used with
a value other then its default for now, but we need this to be configurable
to support some new boards with auto dram config.

2) We always set all CONFIG_DRAM_foo values in defconfigs, even if they match
the defaults, this is done to make it more clear what values are used for a
certain board.

This has been tested on a Mele A1000, Mini-X and a Cubieboard, all 1G
variants, the dram autoconfig code has also been tested on a 512M mk802
(a defconfig for the mk802 is added in a later patch).

6515032e3b sunxi: display: Make lcd display clk phase configurable
While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module
I noticed that the screen flickered. This is caused by the lcd display clk
phase reg value being set to 0, where it should be 1 in this setup.

This commit adds a Kconfig option for the lcd display clk phase, so that we
can set it per board. This defaults to 1, because looking at all the fex
files in sunxi-boards, that is by far the most used value.

This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the
default of 1 with 0, as that is the correct value for those tablets, this
keeps the register settings the same as before this commit.

The Olinuxino-A13 defconfigs are not updated, changing the register setting
for these boards from 0 to 1, this is intentional.

f0ce28e9ed sunxi: Fix CONFIG_UART0_PORT_F build and add it to menuconfig
The CONFIG_UART0_PORT_F option has been supported since
    http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025

This option is primarily useful only for low level u-boot debugging
on tablets, where normal UART0 is difficult to access and requires
device disassembly and/or soldering.

This patch now allows it to be selected from menuconfig. A dependency on
SPL_FEL is added because u-boot does not support booting from NAND yet
and also booting from SD card is impossible when a MicroSD breakout board
is plugged into the SD slot.

Additionally a compilation problem is fixed:

b366fb92c3 sun7i: Set ARMV7_BOOT_SEC_DEFAULT when OLD_SUNXI_KERNEL_COMPAT is set
Old kernels cannot handle booting in non-secure (hyp) mode, so when
OLD_SUNXI_KERNEL_COMPAT is set, also set ARMV7_BOOT_SEC_DEFAULT.

Note that whether to booting secure or non-secure can always be overriden
using the bootm_boot_mode environment variable.

7f2c521f90 sunxi: video: Add cfb console driver for sunxi
This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.

This code is enabled when HPD detects an attached monitor.

Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.

cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues
without the need for a UART.

ea624e1951 ARM: Add arch/arm/cpu/armv7/Kconfig with non-secure and virt options
Add arch/arm/cpu/armv7/Kconfig with non-secure and virt options, this is a
preparation patch for adding an env variable to choose between secure /
non-secure boot on non-secure boot capable systems, specifically this
prepares for adding CONFIG_ARMV7_BOOT_SEC_DEFAULT as a proper Kconfig option.

115200ceb0 sunxi: ehci: Add proper Kconfig options to select the usb Vbus gpio-s
Add proper Kconfig options to select the usb Vbus gpio-s, besides moving to
Kconfig being the right thing to do, an added advantage of this is that it
allows for boards without Vbus gpio-s.
