| | | | | | | | | | | | There are some minor changes with original linux-3.16 file: * the 'model' attribute is added (it used for barebox banner board name); * all "opencores,*-rtlsvn*" 'compatible' attribute values are dropped; these values are not actually used in the device drivers.

* openrisc: generic board: reserve 512K for bareboxAntony Pavlov2014-09-091-2/+2
| | | | | | | | | | | | | | Here is a linker's error message for some configurations: or1k-elf-ld: barebox section `.eh_frame' will not fit in region `ram' or1k-elf-ld: region `ram' overflowed by 16868 bytes This patch increases space reserved for barebox from 256K to 512K so the error's probability is dramatically decreased.

* sandbox: allow "make ARCH=sandbox allyesconfig"Holger Schurig2014-07-221-0/+1
| | | | | | | | | | | | | Compiling the tree with allyesconfig is helpful because different compilers (gcc, clang) or static checkers (e.g. clang's scan-build) can then process and check more code. This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.

* consistently use the same bitops.h fileSascha Hauer2014-07-172-9/+21
| | | | | | | | | | | | | | | | We have many variants of the same bitops.h file. Consistently use the same file for all architectures which completely use the generic bitops versions. Some architectures had static inline versions of functions identically to the generic versions, these are removed and the generic versions are used directly now. Also several architectures depend on the generic find_*_bit functions but didn't have the GENERIC_FIND_NEXT_BIT Kconfig option selected. This is added where needed.

| * openrisc: fix relocation codeFranck Jullien2014-05-221-17/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The relocation code can now relocate from anywhere to the RAM. The old code assumed that the binary was copied to the RAM by some PBL and then it just relocated the .text section from the loaded address to the linked address. Now, it first checks if vectors are somewhere else than the linked address. If yes, there are copied to address 0 (or to the exception vector base address if register EVBAR is present). Then, the .text section is relocated from its current location to the RAM. Signed-off-by: Franck Jullien <franck.jullien@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

What is does is this: * each command has one short description, e.g. "list MUX configuration" * made sure the short descriptions start lowercase * each command has one usage. That string contains just the options, e.g. "[-npn]". It's not part of the long help text. * that is, it doesn't say "[OPTIONS]" anymore, every usable option is listed by character in this (short) option string (the long description is in the long help text, as before) * help texts have been reworked, to make them - sometimes smaller - sometimes describe the options better - more often present themselves in a nicer format * all long help texts are now created with BUSYBOX_CMD_HELP_ macros, no more 'static const __maybe_unused char cmd_foobar_help[]' * made sure the long help texts starts uppercase * because cmdtp->name and cmdtp->opts together provide the new usage, all "Usage: foobar" texts have been removed from the long help texts * BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this is nicer in the source code * BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself * made sure no line gets longer than 77 characters * delibertely renamed cmdtp->usage, so that we can get compile-time errors (e.g. in out-of-tree modules that use register_command() * the 'help' command can now always emit the usage, even without compiled long help texts * 'help -v' gives a list of commands with their short description, this is similar like the old "help" command before my patchset * 'help -a' gives out help of all commands Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | commands: group 'help' outputHolger Schurig2014-05-141-0/+1
|/ | | | | | | | | | | | | | | | | | | The old output of "help" was just producing a long list, that usually scrolled of the screen (even on a X11 terminal). This list is more compact, and also sorted by groups. The old output format (plus grouping) is now available with 'help -v'. Example: Information commands: ?, devinfo, help, iomem, meminfo, version Boot commands: boot, bootm, go, loadb, loads, loadx, loady, saves, uimage ...

* x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-091-1/+2
| | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.

* Set model and hostname at boardlevelSascha Hauer2013-08-162-3/+3
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

OpenRISC is the original flagship project of the OpenCores community. This project aims to develop a series of general purpose open source RISC CPU architectures. A team from OpenCores provided the first implementation, the OpenRISC 1200, written in the Verilog hardware description language. Even though I should have created an mach-or1200 directory, it is not necessary for now. The OpenRISC 1200 CPU is the only one available and it will be for some time.
