| | | | | | | | | Add a driver intended to cope with any VESA-compatible x86 graphics adapter. It will not support ROMs which use OpenFirmware (Forth) since there is no support for that in U-Boot. This means that MAC OS cards will not work. Signed-off-by: Simon Glass <sjg@chromium.org>

* video: Add support for SSD2828 (parallel LCD to MIPI bridge)Siarhei Siamashka2015-01-22-0/+1
| | | | | | | | | | | | | | | | | | | SSD2828 can take pixel data coming from a parallel LCD interface and translate it on the fly into MIPI DSI interface for driving a MIPI compatible TFT display. SSD2828 is configured over SPI interface, which may or may not have MISO pin wired up on some hardware. So a write-only SPI mode also has to be supported. The SSD2828 support code is implemented as a utility function and needs to be called from real display drivers, which are responsible for driving parallel LCD hardware in front of the video pipeline. The usage instructions are provided as comments in the header file.

* | sunxi: video: Add cfb console driver for sunxiLuc Verhaegen2014-11-25-0/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | This adds a fixed mode hdmi driver for the sunxi platform. The fixed mode is a relatively safe 1024x768, more complete EDID handling is currently not provided. Only HDMI is supported today. This code is enabled when HPD detects an attached monitor. Current config is such that 8MB is shaved off at the top of the RAM. This avoids several memory handling issues, most significant is the fact that on linux on ARM you are not allowed to remap known RAM as IO. A clued in display driver will be able to recycle this reserved RAM in future though. cfbconsole was chosen as it provides the most important functionality: a working u-boot console, allowing for the debugging of certain issues without the need for a UART.

| | | | | | | | | | | | | | | | 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>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
