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>

2012-08-08powerpc/p1022ds: fix DIU/LBC switching with NAND enabledTimur Tabi
In order for indirect mode on the PIXIS to work properly, both chip selects need to be set to GPCM mode, otherwise writes to the chip select base addresses will not actually post to the local bus -- they'll go to the NAND controller instead. Therefore, we need to set BR0 and BR1 to GPCM mode before switching to indirect mode. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>

2011-08-04video: Add SHARP LQ084S3LG01 LCD support on P1022DSTimur Tabi
The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board. This device only supports 800x600 resolution, so if that resolution is selected, assume that this is the device. The device is attached to the LVDS port on the P1022DS board. The existing 800x600 entry (for the PDM360NG board) is actually 800x480, so we fix that. To support two different 800x resolutions, the Y-resolution is now passed to fsl_diu_init() and both values are used to pick the proper fb_videomode structure. The data for the 800x600 video mode is originally from Jiang Yutang. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Jiang Yutang <b14898@freescale.com>
2011-04-28powerpc: use 'video-mode' environment variable to configure DIUTimur Tabi
Use the 'video-mode' environment variable (for Freescale chips that have a DIU display controller) to designate the full video configuration. Previously, the DIU driver used the 'monitor' variable, and it was used only to determine the output video port. The old definition of the "monitor" environment variable only determines which video port to use for output. This variable was set to a number (0, 1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The resolution was hard-coded into board-specific code. The Linux command-line arguments needed to be hard-coded to the proper video definition string. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>
2011-04-04p1022ds: allow for board-specific ngPIXIS functionsTimur Tabi
The ngPIXIS is an FPGA used on the reference boards of most Freescale PowerPC SOCs. Although programming the ngPIXIS is mostly standard on all boards that have it, the P1022DS is unique in that the ngPIXIS needs to be programmed in "indirect" mode whenever the video display (DIU) is active. To support indirect mode, and to make it easier to support other quirks on future reference boards, the low-level ngPIXIS functions are all marked as weak, so that board-specific code can override any of them. We take advantage of this feature on the P1022DS, so that we can properly reset the board when the DIU is active.

2010-12-13p1022ds: fix switching of DIU/LBC signalsTimur Tabi
On the P1022, the pins which drive the video display (DIU) are muxed with the local bus controller (LBC), so if the DIU is active, the pins need to be temporarily muxed to LBC whenever accessing NOR flash. The code which handled this transition is checking and changing the wrong bits in PMUXCR. Also add a follow-up read after a write to NOR flash if we're going to mux back to DIU after the write, as described in the P1022 RM.

2010-09-25p1022ds: use weak CFI flash accessors when DIU is enabledTimur Tabi
On the Freescale P1022, the DIU and the LBC share address pins, which means that when the DIU is active (e.g. the console is on the DVI display), NOR flash cannot be accessed. So we use the weak accessor function feature of the CFI flash code to temporarily switch the pin mux from DIU to LBC whenever we want to read or write flash. This has a significant performance penalty, but it's the only way to make it work. This change allows the 'saveenv' command to work when the video display is enabled. Erasing flash and writing to flash (with the 'cp' command) works, but reading from flash (with the 'md' and 'cp' commands) does not. Also, while flash is being written, the video display will be blank. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Anatolij Gustschin <agust@denx.de>
