* spl: if MMCSD_MODE_RAW fails, try MMCSD_MODE_FSGuillaume GARDET2016-02-19-1/+1
| | | | | | | | | | | | | | | | | | | Since commit fd61d39970b9901217efc7536d9f3a61b4e1752a: spl: mmc: add break statements in spl_mmc_load_image() RAW and FS boot modes are now exclusive again. So, if MMCSD_MODE_RAW fails, the board hangs. This patch allows to try MMCSD_MODE_FS then. It has been tested on a beaglebone black to boot on an EXT partition.

| * dm: video: Add a temporary work-around for old stdout varSimon Glass2016-02-11-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Boards with a saved environment may use 'lcd' in their stdout environment variable, expecting that this will enable output to the LCD. When the board moves to use driver model for video, this will no-longer work. Add a work-around to fix this. A warning messages is printed, and we will remove the work-around at the end of 2016.

* | malloc: solve dead code issue in memalign()Stephen Warren2016-02-08-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change to memalign() caused the allocation failure detection code to be dead code; the "retry" logic is always activated under the same condition that the original failure detection code is, and also fully handles any possible failures. This patch solves the presence of dead code. Two alternatives are possible: a) Delete the now-dead test, and rely on the "retry" path to handle any allocation problems, as it does. b) Make the "retry" path fall through to the existing (currently dead) failure detection code, thus making it not-dead. (b) was chosen since it reduces the diff between U-Boot's and the upstream dlmalloc. This should make it marginally easier to import a new version of dlmalloc in the future.

* malloc: work around some memalign fragmentation issuesStephen Warren2016-02-01-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use of memalign can trigger fragmentation issues such as: // Internally, this needs to find a free block quite bit larger than s. // Once the free region is found, any unaligned "padding" immediately // before and after the block is marked free, so that the allocation // takes only s bytes (plus malloc header overhead). p = memalign(a, s); // If there's little fragmentation so far, this allocation is likely // located immediately after p. p2 = malloc(x); free(p); // In theory, this should return the same value for p. However, the hole // left by the free() call is only s in size (plus malloc header overhead) // whereas memalign searches for a larger block in order to guarantee it // can adjust the returned pointer to the alignment requirements. Hence, // the pointer returned, if any, won't be p. If there's little or no space // left after p2, this allocation will fail. p = memalign(a, s); In practice, this issue occurs when running the "dfu" command repeatedly on NVIDIA Tegra boards, since DFU allocates a large 32M data buffer, and then initializes the USB controller. If this is the first time USB has been used in the U-Boot session, this causes a probe of the USB driver, which causes various allocations, including a strdup() of a GPIO name when requesting the VBUS GPIO. When DFU is torn down, the USB driver is left probed, and hence its memory is left allocated. If "dfu" is executed again, allocation of the 32M data buffer fails as described above. In practice, there is a memory hole exactly large enough to hold the 32M data buffer than DFU needs. However, memalign() can't know that in a general way. Given that, it's particularly annoying that the allocation fails! The issue is that memalign() tries to allocate something larger to guarantee the ability to align the returned pointer. This patch modifies memalign() so that if the "general case" over-sized allocation fails, another allocation is attempted, of the exact size the user desired. If that allocation just happens to be aligned in the way the user wants, (and in the case described above, it will be, since the free memory region is located where a previous identical allocation was located), the pointer can be returned. This patch is somewhat related to 806bd245b1ab "dfu: don't keep freeing/reallocating". That patch worked around the issue by removing repeated free/memalign within a single execution of "dfu". However, the same technique can't be applied across multiple invocations, since there's no reason to keep the DFU buffer allocated while DFU isn't running. This patch addresses the root-cause a bit more directly. This problem highlights some of the disadvantages of dynamic allocation and deferred probing of devices. This patch isn't checkpatch-clean, since it conforms to the existing coding style in dlmalloc.c, which is different to the rest of U-Boot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables boards to choose where to/from the environment should be saved/loaded. They can then for example support using the same device (dynamically) from which the bootloader was launched to load and save env data and do not have to define CONFIG_SYS_MMC_ENV_DEV statically. In my use case, the environment needs to be on the same device I booted from. It can be the eMMC or an optional SD card. I therefore would override mmc_get_env_dev in the board code, read the CPU registers to determine where we booted from and return the corresponding device index.
