2019-04-25arm: socfpga: socrates: make rtc workSimon Goldschmidt
This patch makes the on-board RTC work on the socfpga_socrates board. This rtc is present on the board, but it does not work (fails with a timeout). This patch adds a weak pull-up on the I2C0-SCL pin connected to the m41t82 RTC on this board. While the SDA line has a pull-up on the pcb, the pull-up on the SCL line seems to be missing. To work around this, enable the weak-pull-up feature on this pin. After applying this patch, the rtc timeout is gone and the 'date' command can access the rtc chip.

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>
2016-10-27arm: socfpga: socrates: Adding handoff for SDRAM ctrlcfg.extratime1Chin Liang See
Adding new handoff for SDRAM ctrcfg.extratime1 which is required for stable LPDDR2 operation. Since the board is using DDR3, the handoff is set to default value 0. Signed-off-by: Chin Liang See <clsee@altera.com> Cc: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com>

Drop all the common board code, since it is not completely useless. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Chin Liang See <clsee@altera.com> Cc: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-12-20arm: socfpga: socrates: Probe DWC2 UDC from OF instead of hard-coded dataMarek Vasut
This patch adds the necessary OF alias for the UDC node, which let's the code locate the DWC2 UDC base address in OF instead of hard-coding it into the U-Boot binary. The code is adjusted to use the address from OF instead of the hard-coded one. Finally, the hard-coded address is removed and USB DM support is enabled.

2015-12-20arm: socfpga: socrates: Remove Micrel PHY configurationMarek Vasut
The Micrel PHY configuration is now done from OF, so hard-coding the configuration into the board file is no longer necessary.

2015-12-17usb: s3c-otg: Rename usb/s3c_udc.h to usb/dwc2_udc.hMarek Vasut
The driver is actually for the Designware DWC2 controller. This patch renames the global s3c_udc.h header to dwc2_udc.h. The rename is done automatically: $ sed -i "s/s3c_udc\.h/dwc2_udc.h/g" \ `git grep "s3c_udc\.h" | cut -d : -f 1` Signed-off-by: Marek Vasut <marex@denx.de>

The driver is actually for the Designware DWC2 controller. This patch is the second and final to rename global symbol, the s3c_udc_probe() function.

2015-11-30arm: socfpga: Repair SoCrates boardMarek Vasut
This board was constantly parasiting on the CV SoCDK, so split it into it's own separate directory. Moreover, the board config was missing important bits, like simple-bus support in SPL, the DRAM configuration was incorrect and the DTS was also missing the pre reloc bits.
