* net: use common rand()/srand() functionsMichael Walle2012-07-07-1/+3
| | | | | | | | | Replace rand() with the functions from lib/. The link-local network code stores its own seed, derived from the MAC address. Thus making it independent from calls to srand() in other modules. Signed-off-by: Michael Walle <michael@walle.cc> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

* pxe: add support for parsing local syslinux filesRob Herring2012-06-21-0/+6
| | | | | | | | Add a new command "sysboot" which parses syslinux menu files and boots using kernel and initrd specified by menu files. The operation is similar to "pxe boot" except local files on ext2 or fat filesystem are parsed. Signed-off-by: Rob Herring <rob.herring@calxeda.com>

DEBUG_LL_STATE = Link local state machine changes DEBUG_DEV_PKT = Packets or info directed to the device DEBUG_NET_PKT = Packets on info on the network at large DEBUG_INT_STATE = Internal network state changes Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

* Move bootstage timer out of lib/time.cSimon Glass2012-04-10-7/+0
| | | | | | | | | | | | The standalone example does not have get_timer() defined, so we cannot rely on it being available. Move the timer function into boootstage.c to avoid this problem. This corrects a build breakage for the standalone example on some boards. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Matthias Fuchs <matthias.fuchs@esd.eu>
* Revert "Add board_pre_console_putc to deal with early console output"Simon Glass2012-03-23-7/+0
| | | | | | | | | | | This reverts commit 295d3942b806552503243f5cfb36aec6f1b5a9bf. It turns that this really doesn't work very nicely. Instead we should have a pre-console panic function so that we know that further execution is impossible and we don't need to worry about trampling on UARTs, etc. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Wolfgang Denk <wd@denx.de>
* bootstage: Define an optional microsecond timerSimon Glass2012-03-18-0/+7
| | | | | | | | | | | | Define timer_get_boot_us() which returns the number of microseconds since boot. If undefined then we use get_timer() * 1000. We can fit this in a 32-bit register which keeps everyone happy on the efficiency side. It will wrap around after about an hour. If we are still looking at it after an hour then we had better not be timing the boot. Signed-off-by: Simon Glass <sjg@chromium.org>
* bootstage: Create an initial header for boot progress integersSimon Glass2012-03-18-4/+2
| | | | | | | | | | | | At present boot_stage_progress() is called with various magic numbers. The new bootstage.h header will be used to turn these into symbolic names throughout the code. The intent is not that these numbers are passed to Linux. In fact by using an enum to track them we should eventually be able to remove the explict numbers and just have the stages count up from 0.

* Stop using builtin_run_command()Simon Glass2012-03-06-1/+0
| | | | | | | | | | Boards can select either the 'built-in' parser or the hush parser. We should not call builtin_run_command() if we are using the hush parser. We use run_command() instead, since it knows how to call the correct parser. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org>

* Rename run_command() to builtin_run_command()Simon Glass2012-03-06-1/+1
| | | | | | | | | The current run_command() is only one of the parsing options - the other is hush. We should not call run_command() when the hush parser is being used.

* Add board_pre_console_putc to deal with early console outputSimon Glass2011-12-09-0/+7
| | | | | | | | | | | | | | | | This patch adds support for console output before the console is inited. The main purpose of this is to deal with a very early panic() which would otherwise cause a silent hang. A new board_pre_console_putc() function is added to the board API. If provided by the board it will be called in the event of console output before the console is ready. This function should turn on all UARTs and spray the character out if it possibly can. The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Graeme Russ <graeme.russ@gmail.com>

* fdt: Add support for embedded device tree (CONFIG_OF_EMBED)Simon Glass2011-10-26-0/+1
| | | | | | | | | | | | | | | | | This new option allows U-Boot to embed a binary device tree into its image to allow run-time control of peripherals. This device tree is for U-Boot's own use and is not necessarily the same one as is passed to the kernel. The device tree compiler output should be placed in the $(obj) rooted tree. Since $(OBJCOPY) insists on adding the path to the generated symbol names, to ensure consistency it should be invoked from the directory where the .dtb file is located and given the input file name without the path. This commit contains my entry for the ugliest Makefile / shell interaction competition. Signed-off-by: Simon Glass <sjg@chromium.org>

* cache: include asm/cache.h for ARCH_DMA_MINALIGN definitionAnton Staaf2011-10-23-0/+8
| | | | | | | | | | | | | | | | | ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are aligned correctly. In all current cases this means that the DMA buffer will be aligned to at least the L1 data cache line size of the configured architecture. If the board configuration file does not specify the architecture L1 data cache line size then the maximum line size of the architecture is used to align DMA buffers.

* powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun2011-09-29-1/+3
| | | | | | | | | | | | | | | | | Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

| | | | | | | | | | Some SOCs have discontiguously-numbered cores, and so we can't determine the valid core numbers via the FRR register any more.

* Add assert() for debug assertionsSimon Glass2011-09-10-0/+21
| | | | | | | | | | | | | | | assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these. Build errors exposed by this change (and defining DEBUG) are also fixed in this patch. Signed-off-by: Simon Glass <sjg@chromium.org>
* common: fix behavior of ROUND macro when input is already roundedAnton Staaf2011-09-07-1/+1
| | | | | | | | | | | | | | | | | | | Currently when you call ROUND with a value that is already a multiple of the second parameter it will return a value that is one multiple larger, instead of returning the value passed in. There are only two types of usage of ROUND currently, one in various config files to round CONFIG_SYS_MALLOC_LEN to a multiple of 4096 bytes. The other in cmd_sf.c where the incorrect behavior of ROUND is worked around be subtracting one from the length argument before passing it to ROUND. This patch fixes ROUND and removes the workaround from cmd_sf. It also results in all of the malloc pools that use ROUND to compute their size shrinking by 4KB.

* arm: do not force d-cache enable on all boardsAneesh V2011-09-04-0/+1
| | | | | | | | | | | | c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable() to board_init_r(). This enables d-cache for all ARM boards. As a result some of the arm boards that are not cache-ready are broken. Revert this change and allow platform code to take the decision on d-cache enabling. Also add some documentation for cache usage in ARM. Signed-off-by: Aneesh V <aneesh@ti.com>
