* | mmc: Protect `mmc_initialize` from initialising mmc multiple timesDaniel Kochmański2015-07-24-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | `mmc_initialize` might be called multiple times leading to the mmc-controllers being initialised twice, and initialising the `mmc_devices` list head twice which may lead to memory leaks.

* mmc: sdhci.c: Add config option to use a fixed buffer for transfersStefan Roese2015-07-10-0/+15
| | | | | | | | | | | | | | | | | | | | While implementing SDIO/MMC SPL booting for the Marvell Armada 38x, the following problem occured. The SPL runs in internal SRAM which is the L2 cache locked to memory. When the MMC buffers now are located on the stack (or bss), the SDIO controller (SDHCI) can't write into this L2 cache memory. This patch introduces a method to use a fixed buffer that will be used for all transfers by defining CONFIG_FIXED_SDHCI_ALIGNED_BUFFER. This way, the board can use this buffer address located in SDRAM for all transfers. This solves this SPL problem on the A38x and should only be used in the SPL U-Boot version. Tested for SPL booting on Marvell Armada 38x DB-88F6820-GP board.

* mmc: sdhci: Use timer based timeout detection in sdhci_send_command()Stefan Roese2015-07-10-5/+5
| | | | | | | | | | | | | The loop counter based timeout detection does not work on the Armada 38x based board (DB-88F6820-GP). At least with dcache enabled a timeout is detected. Without dcache enabled, the timeout does not occur. Increasing the loop counter solves this issue. But a better solution is to use a timer based timeout detection instead. This patch now implements this timer based detection. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Luka Perkov <luka.perkov@sartura.hr>
* mmc: bcm2835_sdhci: Restore original delay behaviorMarek Vasut2015-06-25-2/+2
| | | | | | | | | | | | | | | | | | Patch 33fe2fb8df01647f97a7bce96a1c7781a7f6d253 titled "mmc: bcm283x: Remove get_timer_us() from mmc driver" incorrectly replaced ad-hoc get_timer_us() function with a plain get_timer(). The get_timer() operates in mSec units instead of uSec though, which caused very slow operation of the driver. Restore the original behavior of the driver, but avoid get_timer_us() and use timer_get_us() instead. The later is part of the standard API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting part of device initialization sets the init_in_progress flag only if the MMC card did not yet come to ready state and needs to continue polling. If the card is SD or if the MMC card became ready quickly, the flag is not set and (if using pre-initialization) the starting phase will be re-executed from mmc_init function. Set the init_in_progress flag in all non-error cases. Also, move flags setting statements around so that the flags are not set in error paths. Also, IN_PROGRESS return status becomes unnecessary, so get rid of it. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The polling loops in sd_send_op_cond and mmc_complete_op_cond functions check the ready flag state at the end of the loop, that is after executing a delay inside the loop, which, in case of exiting with no error, is not needed. Also, one of these loops, as well as the loop in mmc_send_status, have the delay just before exiting on timeout conditions. Restructure all these loops to check the respective conditions before making a delay for the next loop pass, and to appropriately exit without the delay.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | The 'op_cond_response' field in mmc structure contains the response from the last SEND_OP_COND MMC command while making iterational polling of the card. Later it is copied to 'ocr' field, designed to contain the OCR register value, which is actually the same response from the same command. So, these fields have actually the same data, just in different time periods. It's easier to use the same 'ocr' field in both cases at once, without temporary using of the 'op_cond_response' field.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | sun6i and newer (derived) SoCs such as the sun8i-a23, sun8i-a33 and sun9i have a various things in common, like having separate ahb reset control registers, the SID living inside the pmic, custom pmic busses, new style watchdog, etc. This commit introduces a new hidden SUNXI_GEN_SUN6I Kconfig bool which can be used to check for these features avoiding the need for an ever growing list of "#if defined CONFIG_MACH_SUN?I" conditionals as we add support for more "new style" sunxi SoCs. Note that this commit changes the behavior of the gmac and hdmi code for sun8i and the upcoming sun9i devices. This does not matter as sun8i does not have gmac nor hdmi, and sun9i has new hardware-blocks for these so the old code will not work there. Also this is intentional as if a sun8i / sun9i variant which does use the old hwblocks shows up then the GEN_SUN6I code paths will be the right ones to use. For completeness this also adds a SUNXI_GEN_SUN4I bool for A10/A13/A20. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, the mmc devices were always registered in the same order. So dwmmc channel 0 was registered as mmc 0, channel 1 as mmc 1, etc. In case of possibility to boot from more then one device, the CONFIG_SYS_MMC_ENV_DEV should always point to right mmc device. This can be achieved by init boot device as first, so it will be always registered as mmc 0. Thanks to this, the 'saveenv' command will work fine for all mmc boot devices. Exynos based boards usually uses mmc host channels configuration: - 0, or 0+1 for 8 bit - as a default boot device (usually eMMC) - 2 for 4bit - as an optional boot device (usually SD card slot) And usually the boot order is defined by OM pin configuration, which can be changed in a few ways, eg. - Odroid U3 - eMMC card insertion -> first boot from eMMC - Odroid X2/XU3 - boot priority jumper By this commit, Exynos dwmmc driver will check the OM pin configuration, and then try to init the boot device and register it as mmc 0.
