2014-03-16colibri_t20: disable PMIC sleep mode on low supply voltageColibri_T30_LinuxImageV2.1Beta3_20140318Colibri_T20_LinuxImageV2.1Beta3_20140318Apalis_T30_LinuxImageV2.1Beta3_20140318Marcel Ziswiler
The Colibri T20's PMIC enters a sleep mode on low supply voltage < 3.0V ±2.5% (2.92...3.08V). Rising the main supply voltage again does not bring it back to regular operation. Not even a full reset does bring the module back. A full power cycle was required to reboot the system. A long positive pulse on the PMICs resume pin also reboots the system but this pin is only accessible as a test point on the module. This patch configures the PMIC through I2C to not enter this sleep mode plus force it to normal state upon sleep request exit should this ever happen.
2014-03-12apalis/colibri_t20/30: hw boot partition supportMarcel Ziswiler
The new production lot of Apalis T30 2GB V1.0C now features the new SK Hynix H26M42003GMR rather than Hynix H26M42002GMR. Even though both chips feature the same silicon they differ in respective eMMC firmware and therefore have a different hardware boot partition layout. This patch enables hardware boot partition support (via 'mmc dev [dev] [part]' command) and handles NVIDIA's proprietary NvFlash/Fastboot\ behaviour now putting their partition table in the second boot partition rather than the regular user area. While at it also get rid of the spurious 'video=tegrafb' kernel boot argument, adjust the optional ubiargs and add 'noatime' to the usbargs.

Hack backlight GPIO by manually untristating respective pinmux group. While at it add some comment to both the device-tree as well as the gpio command that manual untristating will be required on GPIO pins.
2014-01-30apalis/colibri_t20/t30: add vidargs and fix usbboot optionMarcel Ziswiler
Add default VESA VGA vidargs for our now modedb enabled kernel. This allows easy specifying an alternate parallel RGB resolution. Fix usbboot option to be more in-line with how we do optional MMC/SD card boot on Colibri VF50/VF61. Loads the uimage kernel from the first partition being formatted as VFAT and instructs the kernel to mount the second partition formatted as ext3 as root file system. While at it further checkpatchify our common board file.
2013-11-29apalis/colibri_t30: add more console uart configurationsMarcel Ziswiler
Add more UART configurations to the device trees allowing easy switching of the console UART port by changing the UART base address of the console node within the device tree e.g. for using UART2 on Apalis T30 as follows: console = "/serial@70006300"; To use it for Linux as well one needs to modify the debug_uartport kernel boot argument e.g. for using UART2 on Apalis T30 as follows: setenv setup 'setenv setupargs gpt gpt_sector=${gptoffset} igb_mac= ${ethaddr} no_console_suspend=1 console=tty1 console=ttyS0,${baudrate}n 8 debug_uartport=lsport,3 ${memargs} fbcon=map:1'
2013-10-22apalis_t30: fix linux otg behaviour by not enabling its powerColibri_T30_LinuxImageV2.1Beta1_20131022Colibri_T20_LinuxImageV2.1Beta1_20131022Apalis_T30_LinuxImageV2.1Beta1_20131022Marcel Ziswiler
Fix Linux USB OTG1 behaviour by not enabling USBO1_EN during boot as USB host functionality on OTG1 port is anyway broken under U-Boot. Enabling USBO1_EN fed back via USBO1_VBUS sensing and caused the OTG state machine to get a bogus peripheral state change rather than staying in suspend which failed subsequent host activation. This was especially bad on Ixora where by default the OTG1 port is jumpered for shared host port functionality.

2013-08-12apalis/colibri_t30: implement emmc pt offset auto detectionMarcel Ziswiler
In preparation for the new Apalis T30 SKUs implement eMMC PT offset auto detection. The PT offset has been calculated from the .cfg eMMC partition configuration file using virtual linearised addressing across all eMMC regions as expected by nvflash. Due to the lack of a region control mechanism in nvflash/.cfg flashing utility in order to obtain the actual PT offset from the start of the user region the size of the boot regions must be subtracted. An eMMC device is specified to have 0 or 2 boot regions and they must have the same size ranging from 0 to 2 MiB. The boot region size can be queried from the device through the BOOT_SIZE_MULT field of the response to the EXT_CSD command sequence. Tested on initial samples of Apalis T30 1GB V1.0A, Apalis T30 2GB V1.0B, Apalis T30 2GB V1.0C and Colibri T30 V1.1C.
2013-08-12apalis/colibri_t30: implement memory size auto detectionMarcel Ziswiler

2013-05-01colibri_t20/30: mmc: integrate NVIDIA partition table parsingMarcel Ziswiler
NVIDIA's MMC/SD layout includes a partition table that can be used to generically determine U-Boot environment, kernel, configuration block as well as GPT offsets. As an added benefit this is completely independent of the underlying MMC/SD card used which might differ with various future module versions or particularly cards used for T20 SD boot. Also handles the case of T20 SD boot where the configuration block is still taken from NAND flash while the rest resides on the SD card.

2012-12-04colibri_t30: USB: fix Ethernet detection faultMarcel Ziswiler

If booting from SD card BCT contains information specific to SD card partition layout which is bogus if used for NAND partition parsing. Simply fall back to default offset just like in recovery BCT case. Note: in the future we could parse SD partition table as well to more generically support SD booting from various card densities.
