* 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.

* x86: Add error checking to x86 relocation codeSimon Glass2013-03-04-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This does not actually change normal behaviour, but adds a check that should detect corruption of relocation data (e.g. by using BSS data prior to relocation). Also add additional debugging output when enabled. During this investigation, two situations have been seen: 1. calculate_relocation_address(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; turns into 111166f: b8 83 c4 17 01 mov $0x117c483,%eax whih is beyond the end of bss: 0117b484 g .bss 00000000 __bss_end Somehow the __bss_end here is 255 bytes ahead. 2. do_elf_reloc_fixups(): uintptr_t size = (uintptr_t)&__bss_end - (uintptr_t)&__text_start; Here the __text_start is 0 in the file: 1111d9f: bb a0 e0 13 01 mov $0x113e0a0,%ebx 1111da4: 81 ef 00 00 00 00 sub $0x0,%edi As it happens, both of these are in pre-relocation code.

But in fact all we really need is to set the top of usable RAM, and then the base version will work as is. So instead of allowing the whole calculate_relocation_address() function to be replaced, create board_get_usable_ram_top() which can be used by a board to specify the top of the area where U-Boot relocations to.
