* mmc: Add option to adjust b_max before long readMarek Vasut2020-04-221-0/+16
| | | | | | | | | | | | | | | | | | | | | | | Add getter function which permits adjusting the maximum number of blocks that could be read in a single sustained read transfer based on the location of the source/target buffer and length, before such transfer starts. This is mainly useful on systems which have various DMA restrictions for different memory locations, e.g. DMA limited to 32bit addresses, and where a bounce buffer is used to work around such restrictions. Since the U-Boot bounce buffer is mallocated, it's size is limited by the malloc area size, and the read transfer to such a buffer must also be limited. However, as not all areas are limited equally, the b_max should be adjusted accordinly as needed to avoid degrading performance unnecessarily.

* mmc: add additional quirk for APP_CMD retryJoel Johnson2020-01-161-0/+1
| | | | | | | | | | | | It was observed (on ClearFog Base) that sending MMC APP_CMD returned an error on the first attempt. The issue appears to be timing related since even inserting a puts() short debug entry before the execution added sufficient delay to receive success on first attempt. Follow the existing quirks pattern to retry if initial issuance failed so as to not introduce any delay unless needed. Signed-off-by: Joel Johnson <mrjoel@lixil.net>
* mmc: add a driver callback for power-cycleYann Gautier2019-10-101-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some MMC peripherals require specific power cycle sequence, where some registers need to be written between the regulator is turned off and then back on. This is the case for the MMC IP embedded in STM32MP1 SoC. In STM32MP157 reference manual [1], the power cycle sequence is: 1. Reset the SDMMC with the RCC.SDMMCxRST register bit. This will reset the SDMMC to the reset state and the CPSM and DPSM to the Idle state. 2. Disable the Vcc power to the card. 3. Set the SDMMC in power-cycle state. This will make that the SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are driven low, to prevent the card from being supplied through the signal lines. 4. After minimum 1ms enable the Vcc power to the card. 5. After the power ramp period set the SDMMC to the power-off state for minimum 1ms. The SDMMC_D[7:0], SDMMC_CMD and SDMMC_CK are set to drive “1”. 6. After the 1ms delay set the SDMMC to power-on state in which the SDMMC_CK clock will be enabled. 7. After 74 SDMMC_CK cycles the first command can be sent to the card. The step 3. cannot be handled by the current framework implementation. A new callback (host_power_cycle) is created, and called in mmc_power_cycle(), after mmc_power_off(). The incorrect power cycle sequence has shown some boot failures on STM32MP1 with some SD-cards, especially on cold boots when the input frequency is low (<= 25MHz). Those failures are no more seen with this correct power cycle sequence. [1] https://www.st.com/resource/en/reference_manual/DM00327659.pdf Signed-off-by: Yann Gautier <yann.gautier@st.com>
* spl: dm_mmc: Initialize only the required mmc deviceLokesh Vutla2019-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | In SPL, all the available mmc devices gets initialized during boot. This might not work in cases where clocks are not available for certain mmc devices(other than boot device) and the support for enabling device might not be ready. Texas Instruments' K3 J721E device having a central system controller (dmsc) is one such example falling in this category. Below is the sequence for the failing scenario: - ROM comes up in SD mode and loads SPL by just initialing SD card. - SPL loads dmsc firmware from SD Card. Since ROM has enabled SD, SPL need not enable the SD, just need to re initialize the card. But SPL is trying to initialize other MMC instances which are in disabled state. Since dmsc firmware is not yet available, devices cannot be enabled. So in SPL, initialize only the mmc device that is needed.

* mmc: Rename timeout parameters for clarificationSam Protsenko2019-09-051-6/+6
| | | | | | | | | | | | | | | | | It's quite hard to figure out time units for various function that have timeout parameters. This leads to possible errors when one forgets to convert ms to us, for example. Let's rename those parameters correspondingly to 'timeout_us' and 'timeout_ms' to prevent such issues further. While at it, add time units info as comments to struct mmc fields. This commit doesn't change the behavior, only renames parameters names. Buildman should report no changes at all.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
