[U-Boot] [PATCH] Standalone Apps: Standalone apps should need only exports.h.
by Mike Partington 07 Dec '11

07 Dec '11

From: Mike Partington <mparting(a)windstar.lpdev.prtdev.lexmark.com> Modify exports.h to remove its dependencies on other files, thus enabling standalone apps to require only exports.h from the U-Boot source tree. This appears to be the intent based on the following note: http://lists.denx.de/pipermail/u-boot/2010-January/067174.html Signed-off-by: Mike Partington <mparting(a)windstar.lpdev.prtdev.lexmark.com> --- examples/standalone/atmel_df_pow2.c | 1 + examples/standalone/stubs.c | 1 + include/exports.h | 5 +---- 3 files changed, 3 insertions(+), 4 deletions(-) diff --git a/examples/standalone/atmel_df_pow2.c b/examples/standalone/atmel_df_pow2.c index b5b4503..2e14aba 100644 --- a/examples/standalone/atmel_df_pow2.c +++ b/examples/standalone/atmel_df_pow2.c @@ -8,6 +8,7 @@ #include <common.h> #include <exports.h> +#include <spi.h> #define CMD_ID 0x9f #define CMD_STAT 0xd7 diff --git a/examples/standalone/stubs.c b/examples/standalone/stubs.c index 2d2e709..1ebe43b 100644 --- a/examples/standalone/stubs.c +++ b/examples/standalone/stubs.c @@ -1,3 +1,4 @@ +#include <common.h> #include <exports.h> #ifndef GCC_VERSION diff --git a/include/exports.h b/include/exports.h index 7404a7c..01b83dc 100644 --- a/include/exports.h +++ b/include/exports.h @@ -3,8 +3,6 @@ #ifndef __ASSEMBLY__ -#include <common.h> - /* These are declarations of exported functions available in C code */ unsigned long get_version(void); int getc(void); @@ -12,7 +10,7 @@ int tstc(void); void putc(const char); void puts(const char*); int printf(const char* fmt, ...); -void install_hdlr(int, interrupt_handler_t*, void*); +void install_hdlr(int, void (*interrupt_handler_t)(void *), void*); void free_hdlr(int); void *malloc(size_t); void free(void*); @@ -30,7 +28,6 @@ int ustrtoul(const char *cp, char **endp, unsigned int base); int i2c_write (uchar, uint, int , uchar* , int); int i2c_read (uchar, uint, int , uchar* , int); #endif -#include <spi.h> void app_startup(char * const *); -- 1.7.3.5.g4a3b

[U-Boot] [PATCH] arm/pxa: fix and cleanup of pxa_mem_setup macro v2

[U-Boot] Uboot for Mips
by Rahanesh 13 Sep '11

13 Sep '11

Hi All, I am currently working on MIPS board. I have a 32MB RAM. The address that is shown in uboot when i type bdinfo if 0x80000000 and size is 0x1000000(16MB). I want to increase the size to 32 MB as board has 32 MB RAM. Interesting Finding: When i write any data to 0x80000000 the same data is being written into 0x81000000. Same for all address in the range (data in 0x80000000 - 0x80ffffff is same as 0x81000000 - 0x81ffffff ). It seems that there is a dual mapping . What might be the reason? Please help -- View this message in context: http://www.nabble.com/Uboot-for-Mips-tp24366921p24366921.html Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] [PATCH 1/4 v3] musb: Use name based initialization for musb_config
by Ajay Kumar Gupta 06 Jul '11

06 Jul '11

Changed musb_config initialization for omap3.c, davinci.c and da8xx.c using name of structure fields. This would cause the uninitialized field to be null by default and thus would help in avoiding to init some flags required to be set only for a few selected platforms.

[U-Boot] convention for SPI dummy data?
by wolfgang＠leila.ping.de 13 Jun '11

13 Jun '11

Hi, I have finally got MMC/SD working on my coldfire board and would like to send some patches. However, one of the things I had to change was the dummy data sent out by SPI for read-only transactions. The original driver had all zeros, for SD/MMC all ones (0xFF) is needed. Is such a change acceptable, or is there any configuration option/flag I could use? Regards, Wolfgang
