* sunxi: video: Add support for LCD panels which need to be configured via i2cHans de Goede2015-02-20-0/+10
| | | | | | | | This commits adds support for configuring a a bitbang i2c controller, which is used on some boards to configure the LCD panel (via i2c). Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
* sunxi: Hookup OTG USB controller supportHans de Goede2015-01-22-0/+25
| | | | | | | | | | | Hookup OTG USB controller support and enable the otg controller + USB-keyb on various tablets. This allows tablet owners to interact with u-boot without needing to solder a serial console onto their tablet PCB.

* sunxi: axp221: Add ELDO[1-3] supportSiarhei Siamashka2015-01-22-0/+1
| | | | | | | | | | | | | | | | | | And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way.

* sunxi: axp221: Make dcdc1 voltage configurableHans de Goede2015-01-14-1/+1
| | | | | | | | | | The dcdc1 voltage is typically used as generic 3.3V IO voltage for things like GPIO-s, sdcard interfaces, etc. On most boards this is undervolted to 3.0V to safe battery, but not on all, make it configurable so that we can use the same settings as the original firmware on all boards.

* sunxi: Use PG3 - PG8 as io-pins for mmc1Hans de Goede2014-10-24-3/+3
| | | | | | | | | | None of the known sunxi devices actually use mmc1 routed through PH, where as some devices do actually use mmc1 routed through PG, so change the routing of mmc1 to PG. If in the future we encounter devices with mmc1 routed through PH, we will need to change things to be a bit more flexible.

* sunxi: When we've both mmc0 and mmc2, detect from which one we're bootingHans de Goede2014-10-24-2/+28
| | | | | | | | | | | | | sunxi SOCs can boot from both mmc0 and mmc2, detect from which one we're booting, and make that one "mmc dev 0" so that a single u-boot binary can be used for both the onboard eMMC and for external sdcards. When we're booting from mmc2, we make it dev 0 because that is where the SPL will load the tertiary payload (the actual u-boot binary in our case) from, see: common/spl/spl_mmc.c, which has dev 0 hardcoded everywhere.

* sunxi: use random parts of SID to set ethaddrJonathan Liu2014-07-18-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | Similar to the USB NIC found on OMAP5uEVM, PandaBoard and BeagleBoard-XM boards, the sunxi SoCs have a NIC onboard without an embedded MAC address. Just like the omap used on these boards, the sunxi SoCs do have a unique chip id, in the form of the 128 bit SID register: http://linux-sunxi.org/SID_Register_Guide So mimick the BeagleBoard-XM board code (commit 548a64d8) and use the chip id to generate a unique fixed MAC address. We check for the SID not being all 0, since some early A20 batches shipped without having there SID programmed. Note we use specific parts of the 128 bits, since some parts indicate the SoC family / revision, and thus are fixed. The algorithm for this was taken from the linux-sunxi.org kernels.

It's "correct" in so far as it works (the boards.cfg config stuff #defines things to 1), but I think you are right that it isn't the preferred style.

So rather than fix it to use #ifdef lets drop it.
