* netloop: speed up NetLoopHeiko Schocher2009-02-22-0/+1
| | | | | | | | | | | | | | NetLoop polls every cycle with getenv some environment variables. This is horribly slow, especially when the environment is big. This patch reads only the environment variables in NetLoop, when they were changed. Also moved the init part of the NetLoop function in a seperate function.

* MIPS: Add flush_dcache_range() and invalidate_dcache_range()Stefan Roese2009-01-27-0/+2
| | | | | | | | | | This patch adds flush_/invalidate_dcache_range() to the MIPS architecture. Those functions are needed for the upcoming dcache support for the USB EHCI driver. I chose this API because those cache handling functions are already present in the PPC architecture.

* IOMUX: Add console multiplexing support.Gary Jennejohn2008-12-07-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | Modifications to support console multiplexing. This is controlled using CONFIG_SYS_CONSOLE_MUX in the board configuration file. This allows a user to specify multiple console devices in the environment with a command like this: setenv stdin serial,nc. As a result, the user can enter text on both the serial and netconsole interfaces. All devices - stdin, stdout and stderr - can be set in this manner. 1) common/iomux.c and include/iomux.h contain the environment setting implementation. 2) doc/README.iomux contains a somewhat more detailed description. 3) The implementation in (1) is called from common/cmd_nvedit.c to handle setenv and from common/console.c to handle initialization of input/output devices at boot time. 4) common/console.c also contains the code needed to poll multiple console devices for input and send output to all devices registered for output. 5) include/common.h includes iomux.h and common/Makefile generates iomux.o when CONFIG_SYS_CONSOLE_MUX is set.

* strmhz(): Round numbers when printing clock frequenciesWolfgang Denk2008-10-21-2/+3
| | | | | | | | | Round clock frequencies for printing. Many boards printed off clock frequencies like 399 MHz instead of the exact 400 MHz because numberes were not rounded. This is fixed now. Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | | | ARM, i386, m68k and ppc all have identical implementations of strmhz(). Other architectures don't provide this function at all. This patch moves strmhz() into lib_generic, reducing code duplication and providing a more unified API across architectures. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Fix printf errors.Andrew Klossner2008-07-09-5/+10
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Change initdram() return type to phys_size_tBecky Bruce2008-06-12-1/+1
| | | | | | | | | | | | | | | | | | | This patch changes the return type of initdram() from long int to phys_size_t. This is required for a couple of reasons: long int limits the amount of dram to 2GB, and u-boot in general is moving over to phys_size_t to represent the size of physical memory. phys_size_t is defined as an unsigned long on almost all current platforms. This patch *only* changes the return type of the initdram function (in include/common.h, as well as in each board's implementation of initdram). It does not actually modify the code inside the function on any of the platforms; platforms which wish to support more than 2GB of DRAM will need to modify their initdram() function code. Build tested with MAKEALL for ppc, arm, mips, mips-el. Booted on powerpc MPC8641HPCN. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* Move definition of container_of() to common.hHaavard Skinnemoen2008-06-03-0/+11
| | | | | | | | | | | AVR32 and AT91SAM9 both have their own identical definitions of container_of() taken from the Linux kernel. Move it to common.h so that all architectures can use it. container_of() is already used by some drivers, and will be used extensively by the new and improved SPI API.

Use CONFIG_HAS_POST in the post/ Makefiles to determine should the POST libs be compiled for the selected target platform, or not.

* | crc32: use uint32_t rather than unsigned longMike Frysinger2008-04-24-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The envcrc.c does sizeof(unsigned long) when calculating the crc, but this is done with the build toolchain instead of the target tool chain, so if the build is a 64bit system but the target is 32bits, the size will obviously be wrong. This converts all unsigned long stuff related to crc32 to uint32_t types. Compile tested only: output of ./tools/envcrc when run on a 32bit build system matches that of a 64bit build system.
