2017-03-23arm: mvebu: theadorable: Add 'pcie' test commandStefan Roese
This board specific command tests for the presence of a specified PCIe device (via vendor-ID and device-ID). If the device is not detected, this will get printed. If the device is detected, the board will get resetted so that an easy loop test can be done. The board will reboot until the PCIe device is not detected. Signed-off-by: Stefan Roese <sr@denx.de>
2017-03-23arm: mvebu: theadorable: Add board-specific PEX detection pulse widthStefan Roese
Define a board-specific detection pulse-width array for the SerDes PCIe interfaces. If not defined in the board code, the default of currently 2 is used. Values from 0...3 are possible (2 bits). In this case of the theadorable board, PEX interface 0 needs a value of 0 for the detection pulse width so that the PCIe device (Atheros WLAN PCIe device) is consistantly detected.

2017-03-23arm: mvebu: AXP: Add possiblity to configure PEX detection pulse widthStefan Roese
Tests have shown that on some boards the default width of the configuration pulse for the PEX link detection might lead to non-established PCIe links (link down). Especially under certain conditions (higher temperature) and with specific PCIe devices (in the case on the theadorable board its a Atheros PCIe WLAN device). To enable a board-specific detection pulse width this weak array "serdes_pex_pulse_width[4]" is introduced which can be overwritten if needed by a board-specific version. If the board code does not provide a non-weak version of this variable, the default value will be used. So nothing is changed from the current setup on the supported board. Many thanks to Adam from Marvell for all his insights here and his suggestion about testing with a changed detection pulse width.

2017-03-20part_efi: support padding between the GPT header and partition entriesPhilipp Tomsich
Some architectures require their SPL loader at a fixed address within the first 16KB of the disk. To avoid an overlap with the partition entries of the EFI partition table, the first safe offset (in bytes, from the start of the device) for the entries can be set through CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig) When formatting a device with an EFI partition table, we may need to leave a gap between the GPT header (always in LBA 1) and the partition entries. The GPT header already contains a field to specify the on-disk location, which has so far always been set to LBA 2. With this change, a configurable offset will be translated into a LBA address indicating where to put the entries. Now also allows an override via device-tree using a config-node (see doc/device-tree-bindings/config.txt for documentation). Tested (exporting an internal MMC formatted with this) against Linux, MacOS X and Windows.

AM571x IDK and AM572x IDK have optional LCD Kits that can be purchased. These can be one of OSD101T2045 or the newer OSD101T2587. The LCD panel itself has no registers that can be used to identify the panel, however, the touchscreen controllers on the panels are different. Hence to ease user experience, we can use the touch screen controller's ID information to detect what kind of panel we use and select the appropriate kernel dtb for the platform configuration. NOTE: AM572x IDK default configuration is for LCD Connectivity, however the AM571x IDK has a jumper (J51) that needs to be mounted for the IDK to operate with LCD (Vs two PRUSS ethernet port option).

LCD detection mechanism needs to be added later to differentiate between legacy vs new LCD. For ICSS1 Ethernet pins use the following convention to set the pinmux as PMT data is not yet finalized. - If pin is output, set as PIN_OUTPUT - If pin is input and external pull resistor present set as PIN_INPUT - If pin is input and external pull resistor absent, set pull to same as that of the external PHY's internall pull. - Do not use SLEW_CONTROLon any pin.
