* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* lcd: make 16bpp workAlessandro Rubini2010-03-24-4/+20
| | | | | | | | | Support for 16bpp was supposed to be in the code but was not working. This makes it work and has been tested in the nhk8815 board.

* lcd: remove CONFIG_ATMEL_LCD ifdefs from lcd_setfgcolorAnatolij Gustschin2010-01-27-8/+0
| | | | | | | | | | | | Not all boards defining LCD_COLOR16 are able to set lcd_color_fg/lcd_color_bg correctly. The issue seems to be caused by CONFIG_ATMEL_LCD ifdefs in lcd_setfgcolor() and lcd_setbgcolor(). Actually, the color values passed to these functions are already correct, we don't need to fix them. So remove ifdefs here. Reported-by: Alessandro Rubini <rubini@unipv.it> Signed-off-by: Anatolij Gustschin <agust@denx.de>

* video: move extern declarations from C to headersAlessandro Rubini2009-07-25-16/+0
| | | | | | | | | | | | | | | | This moves some extern declaration from lcd.c to lcd.h, removing unneeded ifdef around a pair of them. Additionally, since gunzip_bmp() was declared static in cmd_bmp.c but extern in lcd.c, I removed the static. The extra "#include <lcd.h>" in cmd_bmp.c is added to ensure the header is consistent with the source. This has been compile-tested on both ARM (at91 boards) and PowerPC (HH405_config, TQM823L_LCD_config, mcc200_config), to test all use combinations.

* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* General help message cleanupWolfgang Denk2009-06-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the help messages were not really helpful; for example, many commands that take no arguments would not print a correct synopsis line, but "No additional help available." which is not exactly wrong, but not helpful either. Commit ``Make "usage" messages more helpful.'' changed this partially. But it also became clear that lots of "Usage" and "Help" messages (fields "usage" and "help" in struct cmd_tbl_s respective) were actually redundant. This patch cleans this up - for example: Before: => help dtt dtt - Digital Thermometer and Thermostat Usage: dtt - Read temperature from digital thermometer and thermostat. After: => help dtt dtt - Read temperature from Digital Thermometer and Thermostat Usage: dtt Signed-off-by: Wolfgang Denk <wd@denx.de>

* Add 16bpp BMP supportMark Jackson2009-02-24-10/+41
| | | | | | | | | | | | | This patch adds 16bpp BMP support to the common lcd code. Use CONFIG_BMP_16BPP and set LCD_BPP to LCD_COLOR16 to enable the code. At the moment it's only been tested on the MIMC200 AVR32 board, but extending this to other platforms should be a simple task !!

* lcd: Let the board code show board-specific infoHaavard Skinnemoen2008-10-27-79/+5
| | | | | | | | | | | | | The information displayed when CONFIG_LCD_INFO is set is inherently board-specific, so it should be done by the board code. The current code dealing with this only handles two cases, and is already a horrible mess of #ifdeffery. Yes, this duplicates some code, but it also allows boards to print more board-specific information; this used to be very difficult.

| | | | | | | | | | | | | The current lcd_display_bitmap() function does not work properly for the Atmel LCD controller. 2 fixes need to be done:- (a) when setting the colour map, use the lcd_setcolreg() function as provided by the Atmel driver (b) the data is never actually written to the lcd framebuffer !!

* Add gzipped logo supportMark Jackson2008-07-31-0/+13
| | | | | | | | | | | | | | The README file states that CONFIG_VIDEO_BMP_GZIP behaves as follows: If this option is set, additionally to standard BMP images, gzipped BMP images can be displayed via the splashscreen support or the bmp command. However, the splashscreen function *only* supports standard BMP images. This patch adds the documented gzip support. Signed-off-by: Mark Jackson <mpfj@mimc.co.uk>
