2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2014-08-01kmp204x/qrio: support for setting the CPU reset request modeBoschung, Rainer
To acheive this, the qrio_uprstreq() function that sets the UPRSTREQN flag in the qrio RESCNF reg is added. Signed-off-by: Rainer Boschung <rainer.boschung@keymile.com> Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com> Reviewed-by: York Sun <yorksun@freescale.com>

2014-05-13kmp204x: complete the reset sequence and PRST configurationValentin Longchamp
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.

2014-05-13kmp204x: handle dip-switch for factory settingsStefan Bigler
Add readout of dip-switch to revert to factory settings. If one or more dip-switch are set, launch bank 0 that contains the bootloader to do the required action. Signed-off-by: Stefan Bigler <stefan.bigler@keymile.com> Signed-off-by: Valentin Longchamp <valentin.longchamp@keymile.com>
2014-05-13kmp204x: Add support for the unit LEDsStefan Bigler
The unit LEDs are managed by the QRIO CPLD. This patch adds support for accessing these LEDs in the QRIO. The LEDs then are set to a correct boot state: - UNIT-LED is red - BOOT-LED is on.

2014-02-03kmp204x: introduce QRIO GPIO functionsValentin Longchamp
The QRIO GPIO functions can be of general interest. They are thus added to a qrio.c and their prototype are available from kmp204x.h. The QRIO prst function are also included in this file, as well as the functions required for the I2C deblocking support (open-drain).
