* ENGR00209899-1 mx6x: add generic gpio interface.Zhang Jiejing2012-05-21-5/+6
| | | | | | | | | | | | | | | | | | | | | | Add generic gpio interface in uboot. Seems more and more gpio operation invoke in uboot, without RAW register operation, we should use generic gpio interface. you should define the CONFIG_MXC_GPIO use generic gpio interface: gpio_request, gpio_direction_output, gpio_direction_input, gpio_set_value, gpio_get_value, etc. Test on MX6Q, MX6DL. Other MX6X should also define this config. Signed-off-by: Zhang Jiejing <jiejing.zhang@freescale.com>

* ENGR00172490: FIX: PMIC registers may not be accessible in u-boot via SPIRobby Cai2012-01-20-2/+6
| | | | | | | | | | | | | | | | The system PMIC registers may not be accessible in u-boot via SPI if function pmic_reg() is called in the latter part of boot up process in u-boot. It is because the imx_spi_slave structure is allocated from malloc() in the spi_setup_slave() function. However, this structure is not completely initialized, which may result in using a dirty control register value at CSPI during transfer. memset() the imx_spi_slave structure after malloc() can resolve this problem Please refer to CT39243849.

Cannot use print_size function when displaying card capacity because it expects a 32 bit integer as input, while mmc->capacity is a 64 bit integer.

| | | | | | | | | | | | Removed delay of 10 ms before each command. There should not be a need to have this delay after the ENGR00156405 patch that polls until card is not busy anymore before proceeding to next cmd.

* ENGR00156405 ESDHC: Add workaround for auto-clock gate errata ENGcm03648Anish Trivedi2011-09-13-2/+33
| | | | | | | | | | | | The errata, not applicable to USDHC, causes ESDHC to shut off clock to the card when auto-clock gating is enabled for commands with busy signalling and no data phase. The card might require the clock to exit the busy state, so the workaround is to disable the auto-clock gate bits in SYSCTL register for such commands. The workaround also entails polling on DAT0 bit in the PRSSTAT register to learn when busy state is complete. Auto-clock gating is re-enabled at the end of busy state.

* ENGR00156304 eMMC: Need to update partition config after changing boot partitionAnish Trivedi2011-09-08-32/+33
| | | | | | | | | | | | | | | | After enabling boot partition on an eMMC using "mmc bootpart" command, the partition configuration variable that is supposed to track this value on the eMMC is not updated. This leads to stale and possibly inaccurate boot partition number being printed when "mmcinfo" command is used, thereby confusing the user. The fix is to update the part_config variable of mmc struct with the new value that was just written to the eMMC. Also removed condition that restricted boot_bus_width programming (for fastboot) to eMMC with DDR support only. Now, even non-DDR capable eMMCs can be programmed for fastboot (in SDR mode).

* ENGR00152755 MX6 Switch DRAM init script from plugin to DCD for emmc fastbootAnish Trivedi2011-07-06-2/+6
| | | | | | | | | | | | | | | | | ROM requires DCD table instead of plugin to initialize DRAM if emmc fastboot mode is to be used. Therefore, switched the DRAM script from plugin to DCD table. The DCD table created is based on the following RVD script: Arik_init_DDR3_528MHz_002.inc found at http://compass.freescale.net/livelink/livelink?func=ll&objId=222928845 When fastboot mode is used by ROM, the MMC_BOOT register of USDHC does not get reset when RSTA bit is set by uboot driver. Therefore, need to write 0 to it manually during driver init. This brings USDHC out of fastboot mode, allowing normal communication with emmc to proceed in uboot. Changed comments for DLL delay to be more accurate. Signed-off-by: Anish Trivedi <anish@freescale.com>

* ENGR00142995 MX50: Enable uSDHC instead of eSDHC for SDR modeAnish Trivedi2011-05-10-6/+30
| | | | | | | | | | | | | | | | | | On SD3 on MX50, there is an option to choose eSDHC or uSDHC controller. By default eSDHC is selected. However, eSDHC shows some borderline timing in SDR mode at 50 MHz, whereas uSDHC shows borderline timing in DDR mode at 50 MHz. Therefore, add a compile time option to uboot for MX50 to select uSDHC in SDR mode or eSDHC in DDR mode on SD3 port. By default the compile time option, CONFIG_MX50_ENABLE_USDHC_SDR, is commented out in the include/configs/mx50_<board>.h file to select eSDHC with DDR mode enabled. Uncomment the define to select uSDHC with only SDR mode enabled. Also increased max frequency supported by ESDHC to 52 MHz instead of 50 MHz. Signed-off-by: Anish Trivedi <anish@freescale.com>
