* kmp204x: reset the Zarlink clocking chips at power up onlyValentin Longchamp2014-08-20-4/+4
| | | | | | | | | | | | | | There is the requirement on the chassis's backplane that when the clocks have been enabled, they then should not disappear. Resetting the Zarlink clocking chips at unit reset violates this requirement because the backplane clocks are not supplied during the reset time. To avoid this side effect, both the Zarlink clocking chips are reset only at power up. Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com>

| | | | | | | | | | | | | | | | | | | | | | | | Check the core timer status register (TSR) for watchdog reset, and and set the QRIO's reset reason flag REASON1[0] accordingly. This allows the appliction SW to identify the cpu watchdog as a reset reason, by setting the REASON1[0] flag in the QRIO.

* | Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* | kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* kmp204x: complete the reset sequence and PRST configurationValentin Longchamp2014-05-13-19/+45
| | | | | | | | | | | | | | | | | | | | | This adds the reset support for the following devices that was until then not implemented: - BFTIC4 - QSFPs This also fixes the configuration of the prst behaviour for the other resets: Only the u-boot and kernel relevant subsystems are taken out of reset (pcie, ZL30158, and front eth phy). Most of the prst config move to misc_init_f(), except for the PCIe related ones that are in pci_init_board and the bftic and ZL30158 ones that should be done as soon as possible. Only the behavior of the Hooper reset is changed according to the documentation as the application is not able to not configure the switch when it is not reset.

* kmp204x: selftest/factory test pin supportValentin Longchamp2014-05-13-0/+13
| | | | | | | | | | | | | | | | | | | This patch defines the post_hotkeys_pressed() function that is used for: - triggering POST memory regions test - starting the test application through the checktestboot command in a script by setting the active bank to testbank The post_hotkeys_pressed return the state of the SELFTEST pin. The patch moves from the complete POST-memory test that is too long in its SLOW version for our production HW test procedure to the much shorter POST-memory-regions test. Finally, the unused #defines for the not so relevant mtest command are removed.

* kmp204x: initial support for PCIe FPGA configurationValentin Longchamp2014-02-03-1/+91
| | | | | | | | | | | | | | The PEXHC PCIe configuration mechanism ensures that the FPGA get configured at power-up. Since all the PCIe devices should be configured when the kernel start, u-boot has to take care that the FPGA gets configured also in other reset scenarios, mostly because of possible configuration change. The used mechanism is taken from the km_kirkwood design and adapted to the kmp204x case (slightly different HW and PCIe configuration).

* kmp204x: I2C deblocking supportRainer Boschung2014-02-03-3/+50
| | | | | | | | | | | | | | | | | | | | This patch adds support for using some GPIOs that are connected to the I2C bus to force the bus lines state and perform some bus deblocking sequences. The KM common deblocking algorithm from board/keymile/common/common.c is used. The GPIO lines used for deblocking the I2C bus are some external GPIOs provided by the QRIO CPLD: - SCL = GPIOA_20 - SDA = GPIOA_21 The QRIO GPIOs act in an open-drain-like manner, for 0 the line is driven low and for 1 the GPIO is set as input and the line gets pulled-up.

* mpc85xx: introduce the kmp204x reference design supportValentin Longchamp2013-10-24-0/+687
This patch introduces the support for Keymile's kmp204x reference design. This design is based on Freescale's P2040/P2041 SoC. The peripherals used by this design are: - DDR3 RAM with SPD support - SPI NOR Flash as boot medium - NAND Flash - 2 PCIe busses (hosts 1 and 3) - 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5) - 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt FPGA - 2 HW I2C busses - last but not least, the mandatory serial port The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb support and was changed according to our design (that means essentially removing what is not present on the designs and a few adaptations). There is currently only one prototype board that is based on this design and this patch also introduces it. The board is called kmlion1.
