* fs/fat/fat_write: Fix buffer alignmentsBenoît Thébaudeau2015-10-111-14/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | set_cluster() was using a temporary buffer without enforcing its alignment for DMA and cache. Moreover, it did not check the alignment of the passed buffer, which can come directly from applicative code or from the user. This could cause random data corruption, which has been observed on i.MX25 writing to an SD card. Fix this by only passing ARCH_DMA_MINALIGN-aligned buffers to disk_write(), which requires the introduction of a buffer bouncing mechanism for the misaligned buffers passed to set_cluster(). By the way, improve the handling of the corresponding return values from disk_write(): - print them with debug() in case of error, - consider that there is an error is disk_write() returns a smaller block count than the requested one, not only if its return value is negative. After this change, set_cluster() and get_cluster() are almost symmetrical. Signed-off-by: Benoît Thébaudeau <benoit@wsystem.com>

| | | | | | | | | | | | | | This patch changes the default "root=" parameter to "/dev/sda2". Many linux based distros use /dev/sda1 for their boot partition; this is often not a rootfs that can be used by the "root=" parameter.

* vexpress64: juno: add alternate kernel and device tree filenamesRyan Harkin2015-10-111-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | The latest Juno firmware stores the files in NOR flash as "norkern" for kernel binary, "board.dtb" for the device tree binary. The "old" firmware used the name "Image" for the kernel binary and "juno" for the device tree binary. Rather than just change the default U-Boot configuration to use the new names, breaking users with the old firmware, attempt to load the default filename first. If that fails, attempt to load the alternate filename. I've echo'd that we are loading the alternate file to counter the output from "afs load" shown if the first load attempt fails. For example, I see output like this on my Juno board when it's configured the with the "old" firmware: image "norkern" not found in flash Loading Image instead of norkern loaded region 0 from 08500000 to 80000000, 00AB6318 bytes image "board.dtb" not found in flash Loading juno instead of board.dtb loaded region 0 from 0A000000 to 83000000, 00003188 bytes Signed-off-by: Ryan Harkin <ryan.harkin@linaro.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | The pcDuino1 board unconditionally provides 5V to USB host receptacles. The pcDuino2 board has a voltage regulator, controlled by the PD2 pin which is pulled-up by default (so that the USB power is also enabled by default). Not specifying pins for enabling USB power in the defconfig means that the PH3 and PH6 pins are driven high by default. The PH6 pin is available on the Arduino-compatible expansion header and touching it is not nice (this may be even dangerous, depending on what kind of role is assigned to this particular pin by various Arduino shields). This patch explicitly configures the USB VBUS pins to "", which means that no pins should be touched. The patch has been tested on a pcDuino2 board and USB still works.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when driver model starts up it finds the root uclass and the pinctrl uclass. This is because even the root node handles pinctrl processing. But this is not useful. The root node is not a real hardware device so cannot require any particular pinmux settings. Also it means that the memory leak tests fails, since they end up freeing more memory than they allocate: the marker it set after the root device and pinctrl uclass are allocated, and later once the pinctrl uclass is freed the memory used by driver model is less than when the marker was set. If a platform needs 'core' pin mulitplex settings it can do this with a driver that is probed on start-up. It would be an abuse of the root node to use this for pinctrl. To avoid this problem, only process pinctrl settings for non-root nodes. Signed-off-by: Simon Glass <sjg@chromium.org>
* | rockchip: Reconfigure the malloc based to point to system memorySjoerd Simons2015-10-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When malloc_base initially gets setup in the SPL it is based on the current (early) stack pointer, which for rockchip is pointing into SRAM. This means simple memory allocations happen in SRAM space, which is somewhat unfortunate. Specifically a bounce buffer for the mmc allocated in SRAM space seems to cause the mmc engine to stall/fail causing timeouts and a failure to load the main u-boot image. To resolve this, reconfigure the malloc_base to start at the relocated stack pointer after DRAM has been setup. For reference, things did work fine on rockchip before 596380db was merged to fix memalign_simple due to a combination of rockchip SDRAM starting at address 0 and the dw_mmc driver not checking errors from bounce_buffer_start. As a result, when a bounce buffer needed to be allocated mem_align simple would fail and return NULL. The mmc driver ignored the error and happily continued with the bounce buffer address being set to 0, which just happened to work fine..

The new API introduced fdtdec_get_addr_size_auto_parent() for the 'reg' property parsing, but the implementation assumes, that #size-cells can't be less than 1. This causes that the following children's 'reg' property can't be reached: parent@0x0 { #address-cells = <1>; #size-cells = <0>; children@0x100 { reg = < 0x100 >; }; }; Change the condition value from '1' to '0', which allows parsing property with at least zero #size-cells, fixes the issue.

In this case, the DT property must be large enough to contain both values. b) With sizep NULL, in which case only an address is parsed from DT. In this case, the DT property only need be large enough to contain this address value. Commit 02464e386bb5 "fdt: add new fdt address parsing functions" broke this relaxed checking, and required the DT property to contain both an address and a size value in all cases. Fix fdtdec_get_addr_size() to vary ns based on whether the size value is being parsed from the DT or not. This is safe since the function only parses the first entry in the property, so the overall value of (na + ns) need not be accurate, since it is never used to step through the property data to find other entries. Besides, this fixed behaviour essentially matches the original behaviour before the patch this patch fixes. (The original code validated that the property was exactly the length of either na or (na + ns), whereas the current code only validates that the property is at least that long. For non-failure cases, the two behaviours are identical).

When we get to adding accelerometer support the plan is to add some kind of autodetection and mangle the dt accordingly (likely using the new quirks mechanism). For now this is a non issue as we do not yet have accelerometer support, and in the future, some sort of auto-detect is the way to go as we cannot expect users to exactly know what is inside their tablet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size allocation for SPL is increased in all cases to match the already-expanded value used on Tegra124. This is both for general consistency, and because the seaboard build trips over the limit already when using one of the ARM compilers packaged with 14.04. For the record, when building Seaboard: arm-linux-gnueabi- SPL is too big by 0x36 bytes arm-linux-gnueabihf- SPL fits by 0x2a bytes arm-none-eabi- SPL fits by 0xa bytes (Those figures are from builds with the expanded SPL size allocation, relative to the non-expanded SPL size limit; they're better by about 6 bytes in the more constrained build.)

| * ARM: tegra: don't enable GPIOs until direction is setStephen Warren2015-10-021-12/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's GPIO driver currently enables pins as GPIO as soon as they're requested. This is not safe, since the desired direction and output value are not yet known. This could cause a glitch on the output pins between gpio_request() and gpio_direction_*(), depending on what values happen to be in the GPIO controller's in/out and out-value registers vs. the final desired configuration. To solve this, defer enabling pins as GPIOs until some gpio_direction_*() is invoked, and the desired configuration is explicitly programmed. In theory this change could cause regressions, if code exists that claims a GPIO, never explicitly sets a direction, and then gets/sets the GPIO value based on that assumption. However, I've read through all the Tegra- related board files and device drivers that touch GPIOs and I do not see such buggy code anywhere.

| * ARM: tegra: fix GPIO init table programmingStephen Warren2015-10-021-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Tegra's gpio_config_table() currently uses common GPIO APIs. These used to work without requesting the GPIO, but since commit 2fccd2d96bad "tegra: Convert tegra GPIO driver to use driver model" no longer do so. This prevents any of the GPIO initialization table from being applied to HW. Fix gpio_config_table() to directly program the HW to solve this.
