* x86: Use sections header to obtain link symbolsSimon Glass2013-03-15-12/+5
| | | | | | | These are defined in asm-generic/sections.h, so remove them from architecture-specific files. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Adjust board_r.c for x86Simon Glass2013-03-15-2/+21
| | | | | | | For x86 the global_data is managed entirely by the start.S code so we do not need to touch it. However, we do have some more initcalls to add. Signed-off-by: Simon Glass <sjg@chromium.org>
* x86: Adjust board_f.c for x86Simon Glass2013-03-15-2/+81
| | | | | | | | | | | | For x86, things have adjusted somewhat since this series was originally written. It has its own way of running through initcalls which is actually nicer than others archs. Unfortunately this does introduce exceptions. We will soon require use of generic board on x86, but until then we need to fit in with what is there, and treat x86 as a special case.

* ppc: Enable generic board supportSimon Glass2013-03-15-0/+12
| | | | | | | This enables generic board support so that ppc boards can define CONFIG_SYS_GENERIC_BOARD. Signed-off-by: Simon Glass <sjg@chromium.org>

* Adjust board_f.c for ppcSimon Glass2013-03-15-2/+332
| | | | | | | | This adds ppc features to the generic pre-relocation board init. This is a separate commit so that these features are clearly shown. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add CONFIG_SYS_SYM_OFFSETS to support offset symbolsSimon Glass2013-03-15-0/+21
| | | | | | | | | | | | Link symbols as created by the link script can either be absolute or relative to the text start. This option switches between the two options so that we can support both. As we convert architectures over to generic board, we can see if this option is actually needed, or whether it is possible to unify this feature also. Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: Enable generic board supportSimon Glass2013-03-15-0/+15
| | | | | | | This enables generic board support so that ARM boards can define CONFIG_SYS_GENERIC_BOARD. Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: Remove use of board_early_init_r/last_stage_init()Simon Glass2013-03-15-4/+4
| | | | | | | | | | | These boards define CONFIG_LAST_STAGE_INIT and CONFIG_BOARD_EARLY_INIT_R but these options are not available on ARM. Move them into the powerpc common file instead. This change affects: km_kirkwood_pci, mgcoge3un, kmnusa, kmcoge5un, km_kirkwood and portl2. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add spl load featureSimon Glass2013-03-15-0/+13

* Introduce generic pre-relocation board_f.cSimon Glass2013-03-15-6/+591
| | | | | | | | | | | | This file handles common pre-relocation init for boards which use the generic framework.

* Declare watchdog functions in watchdog.hSimon Glass2013-03-15-9/+22
| | | | | | | | These functions are only available for powerpc and are not declared in a header file. We want to use the rest function in two places (board_f and board_r), so declare the functions in watchdog.h. Signed-off-by: Simon Glass <sjg@chromium.org>
* __HAVE_ARCH_GENERIC_BOARD controls availabilty of generic boardSimon Glass2013-03-15-0/+18
| | | | | | | | | | | We are introducing a new unified board setup. Add a check to make sure that board config files do not define CONFIG_SYS_GENERIC_BOARD unless their architecture defines __HAVE_ARCH_GENERIC_BOARD __HAVE_ARCH_GENERIC_BOARD will currently not be the default setting, but we can switch this later when most architecture support generic board. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce a basic initcall implementationSimon Glass2013-03-15-0/+65
| | | | | | | | | | | This library supports calling a list of functions one after the other. It is intended that we move to a more powerful initcall implementation as proposed by Graeme Russ <graeme.russ@gmail.com>. For now, this allows us to do the basics. Signed-off-by: Simon Glass <sjg@chromium.org>
* Change stub example to use asm-generic/sections.hSimon Glass2013-03-15-13/+12
| | | | | | | We can use the declarations of __bss_start and _end from this header instead of declaring them locally. Signed-off-by: Simon Glass <sjg@chromium.org>
* arm: Use sections header to obtain link symbolsSimon Glass2013-03-15-4/+3
| | | | | | | Include this header to get access to link symbols, which are otherwise removed. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce generic link section.h symbol filesSimon Glass2013-03-15-4/+447
| | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
* Replace __bss_end__ with __bss_endSimon Glass2013-03-15-207/+207
| | | | | | | | | | | | | Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
* Introduce generic u-boot.h fileSimon Glass2013-03-15-0/+162
| | | | | | | | This file holds the board info structure. We need this to be generic for the unified board series, so create a structure which contains the basic fields required by the main architectures. Signed-off-by: Simon Glass <sjg@chromium.org>
* I2C: S3C24X0: Bug fixes in i2c_transferRajeshwari Shinde2013-03-12-8/+6
| | | | | | | | | | | | | | | | | | This patch corrects the following issues 1) Write the correct M/T Stop value to I2CSTAT after i2c write. According to the spec, after finish the data transmission, we should write a M/T Stop (I2C_MODE_MT | I2C_TXRX_ENA) to I2CSTAT instead of a M/R Stop (I2C_MODE_MR | I2C_TXRX_ENA). 2) Not split the write to I2CSTAT into 2 steps in i2c read. According to the spec, we should write the combined M/R Start value to I2CSTAT after setting the slave address to I2CDS 3) Fix the mistake of making an equality check to an assignment. In the case of I2C write with the zero-length address, while tranfering the data, it should be an equality check (==) instead of an assignment (=).

* CONFIG_BOOTDELAY default should not affect runtimeJoe Hershberger2013-03-12-8/+6
| | | | | | | | | | | Because the code that handles bootdelay is compiled in conditionally based on the default value, you are restricted in the default, regardless of what you want the runtime options to be. Change the source to always check if any default is given so that other values can be selected and used at runtime. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

* env: fix "env ask" commandWolfgang Denk2013-03-12-26/+28
| | | | | | | | | | | | | | | | | | | | The "env ask" traditionally uses a somewhat awkward syntax: env ask name [message ...] [size] So far, when a mesage was given, you always also had to enter a size. If you forgot to do that, the command would terminate without any indication of the problem. To avoid incompatible changes of the interface, we now check the last argument if it can be converted into a decimal number. If this is the case, we assume it is a size; otherwise we treat it as part of the message. Also, add a space after the message fore easier reading, and clean up help mesage.

* MAKEALL: fix kill_children for BSD hostsAndreas Bießmann2013-03-11-2/+14
| | | | | | | | | | | | | | | | | ps on BSD hosts (like OS X) do not provide the --no-headers switch nor understand the AIX format descriptions. Unfortunately there seems no solution to get the PIDs of children in a platfrom independent manner. Therefore detect the OS and decide upon that which way to go. This patch makes the MAKEALL script cleanly stoppable on bare OS X when using the parallel builds of targets. Additionally this patch removes double call to grep by a single call to sed for GNU style child PID detection.

* Feature Removal: disable "mtest" command by defaultWolfgang Denk2013-03-11-4/+125
| | | | | | | | | | | | | | | | | | | | | The "mtest" command is of little practical use (if any), and experience has shown that a large number of board configurations define useless or even dangerous start and end addresses. If not even the board maintainers are able to figure out which memory range can be reliably tested, how can we expect such from the end users? As this problem comes up repeatedly, we rather do not enable this command by default, so only people who know what they are doing will be confronted with it. As this changes the user interface, we allow for a grace period before this change takes effect. For now, we make "mtest" configurable through the CONFIG_CMD_MEMTEST variable, which is defined in include/config_cmd_default.h; we also add an entry to doc/feature-removal-schedule.txt which announces the removal of this default setting in two releases from now, i. e. with v2013.07.
