* stdio: Pass device pointer to stdio methodsSimon Glass2014-07-23-101/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
* stdio: Remove redundant code around stdio_register() callsSimon Glass2014-07-23-42/+0
| | | | | | | | | | | | | There is no point in setting a structure's memory to NULL when it has already been zeroed with memset(). Also, there is no need to create a stub function for stdio to call - if the function is NULL it will not be called. This is a clean-up, with no change in functionality.

* Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>
* sandbox: Set up global data before board_init_f()Simon Glass2014-07-23-1/+5
| | | | | | | | | | | | At present sandbox defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that the global_data pointer is set up in board_init_f(). If we set up and zero the global data before calling board_init_f() then we don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA. Make this change to simplify the init process.

* m68k: define __kernel_size_t as unsinged int againMasahiro Yamada2014-07-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ddc94378d changed the definition of __kernel_size_t from unsigned int to unsigned long. It is true that it fixed warnings on some crosstools but it increased warnings on the others. The problem is that we cannot see consistency in terms of the typedef of __kernel_size_t on M68K architecture. However, I'd like to suggest to have __kernel_size_t to be unsigned int again. Rationale: [1] Linux Kernel defines __kernel_size_t on M68K as unsigned int. Let's stick to the Linux's way. [2] We want to build boards with popular pre-built toolchains, not the one locally-built by indivisuals. I think m68-linux-gcc which can be downloaded from www.kernel.org is the candidate for our _recommended_ toolchains. With this patch, all the m68k boards can be built without any warnings. Give it a try with the following crosstools: https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/ x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz or https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ x86_64-gcc-4.9.0-nolibc_m68k-linux.tar.xz (The latter is newer.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest GCC is so clever that it reports more warnings than old ones did: ------------------------------>8------------------------------ board/freescale/m5253demo/flash.c: In function 'flash_get_offsets': board/freescale/m5253demo/flash.c:65:23: warning: iteration 2047u invokes undefined behavior [-Waggressive-loop-optimizations] info->start[k + 1] = info->start[k] + CONFIG_SYS_SST_SECTSZ; ^ board/freescale/m5253demo/flash.c:64:3: note: containing loop for (k = 0, j = 0; j < CONFIG_SYS_SST_SECT; j++, k++) { ^ ------------------------------8<------------------------------ The cause of the warning is like this: The for statement iterates 2048 times in flash_get_offsets() func. (Notice CONFIG_SYS_SST_SECT is defined as 2048) The last iteration does info->start[2048] = info->start[2047] + CONFIG_SYS_SST_SECTSZ; causing an undefined behavior. (Please note the array size of info->start is 2048. CONFIG_SYS_MAX_FLASH_SECT is defined as 2048 for this board.) This commit fixes that so as not to overrun the info->start array.

| | | | | | | | | | | | | | | | | This has been disabled for ARM in initr_scsi since that function was introduced. However it works fine for me on Cubieboard and Cubietruck (with the upcoming AHCI glue patch). I also tested on two random ARM platforms which seem to define CONFIG_CMD_SCSI: - highbank worked fine (on midway hardware) - omap5_uevm built OK and I confirmed using objdump that things were as expected (i.e. the default weak scsi_init nop was used). While there remove the mismatched comment from the #endif (omitting the comment seems to be the prevailing style in this file).

* AHCI: Increase link timeout to 200msIan Campbell2014-07-22-1/+1
| | | | | | | | | | | | | In 73545f75b66d "ahci: wait longer for link" I increased the timeout to 40ms based on the observed behaviour of a WD disk on a Cubietruck. Since then Karsten Merker and myself have both observed timeouts with HGST disks (Karsten on Cubietruck, me on Cubieboard2). Increasing the timeout to ~175ms fixes this, so go to 200ms for a bit of headroom.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This tool helps to create/update the mailmap file. It runs 'git shortlog' internally and searches differently spelled author names which share the same email address. The author name with the most commits is asuumed to be a canonical real name. If the number of commits from the cananonical name is equal to or greater than 'MIN_COMMITS' (=50), the entry for the cananical name will be output. ('MIN_COMMITS' is used here because we do not want to create a fat mailmap by adding every author with only a few commits.) If there exists a mailmap file specified by the mailmap.file configuration options or '.mailmap' at the toplevel of the repository, it is used as a base file. The base file and the newly added entries are merged together and sorted alphabetically (but the comment block is kept untouched), and then printed to standard output. Usage ----- scripts/mailmapper prints the mailmapping to standard output. scripts/mailmapper > tmp; mv tmp .mailmap will be useful for updating '.mailmap' file.
