led_display: split led display support into generic and hw-dependent parts

2010-10-12T20:44:33Z

Split the display command into generic interface and hardware-specific realization for PDSP188x LED display found on hmi1001 and manroland boards. Simple interface for LED displays is defined in include/led-display.h and described in doc/README.LED_display. Driver-specific implementation was moved into drivers/misc/pdsp188x.c file (enabled with CONFIG_PDSP188x set). Signed-off-by: Ilya Yanok

MXC: Fix byte-ordering in SPI driver for i.MX31/i.MX51

2010-09-30T12:42:14Z

The actual SPI driver for i.MX31 and i.MX51 controller use a wrong byte ordering, because it is supposed to work only with Freescale's devices, as the Power Controllers (PMIC). The driver is not suitable for general purposes, because the buffers passed to spi_xfer must be 32-bit aligned, as it is used mainly to send integer to PMIC devices. The patch drops any kind of limitation and makes the driver useful with devices controlled sending commands composed by single bytes (or by a odd number of bytes), such as spi flash, sensor, etc. Because the byte ordering is changed, any current driver using this controller must be adapted, too.

cmd_usage(): simplify return code handling

2010-07-24T18:43:57Z

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. Signed-off-by: Wolfgang Denk

powerpc/p3041: Add various p3041 related defines

2010-07-20T09:41:19Z

There are various locations that we have chip specific info: * Makefile for which ddr code to build * Added p3041 to cpu_type_list and SVR list * Added number of LAWs for p3041 * Set CONFIG_MAX_CPUS to 4 for p3041 Signed-off-by: Kumar Gala

powerpc/p5020: Add various p5020 related defines (and p5010)

2010-07-20T09:41:19Z

There are various locations that we have chip specific info: * Makefile for which ddr code to build * Added p5020 & p5010 to cpu_type_list and SVR list * Added number of LAWs for p5020 * Set CONFIG_MAX_CPUS to 2 for p5020 Signed-off-by: Kumar Gala

fsl_law.c: Add print_laws() for FSL_CORENET platforms.

Add printing of LAWBARH/LAWBARL for FSL_CORENET platforms. Signed-off-by: Becky Bruce Signed-off-by: Kumar Gala

drivers/misc/fsl_law.c: Rearrange code to avoid duplication

2010-07-16T15:55:09Z

The current code redefines functions based on FSL_CORENET_ vs not - create macros/inlines instead that hide the differences. Signed-off-by: Becky Bruce Signed-off-by: Kumar Gala

gpio_led: add gpio_request to __led_init

Make sure that argv[] argument pointers are not modified.

2010-07-04T21:55:42Z

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) { ...
