* video: Add SHARP LQ084S3LG01 LCD support on P1022DSTimur Tabi2011-08-04-1/+1
| | | | | | | | | | | | | | | | | 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>
* powerpc: use 'video-mode' environment variable to configure DIUTimur Tabi2011-04-28-13/+3
| | | | | | | | | | | | | | | | 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>
* fsl_diu_fb: further refactoring of FSL DIU codeAnatolij Gustschin2010-09-25-55/+7
| | | | | | | | Move common code to the fsl_diu_fb.c file and remove obsolete code from board files (aria, mpc8610hpcd and pdm360ng). Move fsl_diu_fb.h file to the include directory. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* fsl: refactor MPC8610 and MPC5121 DIU code to use existing bitmap and logo ↵Timur Tabi2010-09-21-65/+3
| | | | | | | | | | features The Freescale MPC8610 and MPC5121 DIU code had re-implement two features that already existed in U-Boot: bitmap drawing and top-of-screen logo (CONFIG_VIDEO_LOGO). So delete the 8610-specific code and use the built-in features instead. Signed-off-by: Timur Tabi <timur@freescale.com>
* cmd_usage(): simplify return code handlingWolfgang Denk2010-07-24-4/+2
| | | | | | | | | | | | | | | | Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.

* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hush shell dynamically allocates (and re-allocates) memory for the argument strings in the "char *argv[]" argument vector passed to commands. Any code that modifies these pointers will cause serious corruption of the malloc data structures and crash U-Boot, so make sure the compiler can check that no such modifications are being done by changing the code into "char * const argv[]". This modification is the result of debugging a strange crash caused after adding a new command, which used the following argument processing code which has been working perfectly fine in all Unix systems since version 6 - but not so in U-Boot: int main (int argc, char **argv) { while (--argc > 0 && **++argv == '-') { /* ====> */ while (*++*argv) { switch (**argv) { case 'd': debug++; break; ... default: usage (); } } } ... } The line marked "====>" will corrupt the malloc data structures and usually cause U-Boot to crash when the next command gets executed by the shell. With the modification, the compiler will prevent this with an error: increment of read-only location '*argv' N.B.: The code above can be trivially rewritten like this: while (--argc > 0 && **++argv == '-') { char *arg = *argv; while (*++arg) { switch (*arg) { ...

* video: cfb_console: add weak default video_set_lut()Anatolij Gustschin2010-06-14-14/+0
| | | | | | | | | Do not enforce drivers to provide empty video_set_lut() if they do not implement indexed color (8 bpp) frame buffer support. Add default function to the cfb_console driver and remove empty video_set_lut() functions. Signed-off-by: Anatolij Gustschin <agust@denx.de>

* Move arch/ppc to arch/powerpcStefan Roese2010-04-21-0/+188
As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
