* 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>
* ENGR00139206 MX6 USDHC eMMC 4.4 supportAnish Trivedi2011-07-05-14/+42
| | | | | | | | | | | New bit definitions in USDHC. Added is_usdhc variable to fsl_esdhc_cfg to distinguish between ESDHC and USDHC. Enabled DDR mode support in USDHC. Created a config to customize target delay for DDR mode. Modified USDHC pad settings to make DDR mode work for all emmcs at 50 MHz. 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>
* ENGR00141335-1: Use bypass way to set ddr dll in mx53Terry Lv2011-04-11-1/+1
| | | | | | | | Usually dll setup for eMMC4.4 DDR is required to polling SLV_LOCK status bit. However the system hangs when polling for SLV_LOCK bit. The temporary workaround is to force slave override mode to bypass it. Signed-off-by: Terry Lv <r65388@freescale.com>

* ENGR00140873: MMC may wrongly regconize 2GB eMMC as high capacityTerry Lv2011-03-21-2/+4
| | | | | | | | | | | | MMC driver may wrongly regconize some 2GB eMMC as high capacity card. This patch is picked from community. A non-zero value of SEC_COUNT does not indicate that the card is sector addressed. According to the MMC specification, cards with a densitygreater than 2GiB are sector addressed.

* ENGR00136863-2: Fix mx53 CMD12 issue.Terry Lv2010-12-29-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | As in mx53 and lster socs, when using CMD12, cmdtype need to be set to ABORT, otherwise, next read command will hang. This is a software Software Restrictions in spec 29.7.8. For pre-defined multi-block read operation, i.e., The number of blocks to read has been defined by previous CMD23 for MMC, or pre-defined number of blocks in CMD53 for SDIO/SDCombo, or whatever multi-block read without abort command at card side, an abort command, either automatic or manual CMD12/CMD52, is still required by ESDHCV2 after the pre-defined number of blocks are done, to drive the internal state machine to idle mode. In this case, the card may not respond to this extra abort command and ESDHCV2 gets Response Timeout. It is recommended to manually send an abort command with RSPTYP[1:0] both bits cleared.

* mmc: fix response decoding on little endianRabin Vincent2009-06-02-10/+10
| | | | | | | | | | | | | | | | The mmc code defines the response as an array of chars. However, it access the response bytes both as (i) an array of four uints (with casts) and (ii) as individual chars. The former case is used more often, including by the driver when it assigns the response. The char-wise accesses are broken on little endian systems because they assume that the bytes in the uints are in big endian byte order. This patch fixes this by changing the response to be an array of four uints and replacing the char-wise accesses with equivalent uint-wise accesses. Signed-off-by: Rabin Vincent <rabin@rab.in>
