2012-05-08mmc: add the quirk to use the sdhci for samsung-socJaehoon Chung
To support the Samsung-SoC, added the basically functions. Samsung-SoC didn't used the SDHCI_CTRL_HISPD. And added set_control_reg callback for s3c64xx.

2012-05-08mmc: sdhci: add the quirk for broken r1b responseJaehoon Chung
When response type is R1b, mask value is added the SDHCI_INT_DAT_END. but in while(), didn't check that flag. So sdhci controller didn't work fine. CMD6 didn't always complete. So add the quirks for broken r1b response and add the timeout value to prevent the infinite loop.

2012-05-08i.MX28: Lower the amount of blocks transfered in one DMA cycleMarek Vasut
Some MMC cards, like my ancient 32.0MB SanDisk RS-MMC cards had issue if b_max was set to 0x40 and DMA was enabled. Lower this value to 0x20, which allows these cards to work too.

2012-05-08mmc: fsl_esdhc: Poll until card is not busy anymoreDirk Behme
This patch imports parts of two patches from the Freescale U-Boot with the following commit messages: ENGR00156405 ESDHC: Add workaround for auto-clock gate errata ENGcm03648 http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=e436525a70fe47623d346bc7d9f08f12ff8ad787 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. ENGR00156670-1 ESDHC/USDHC: Remove delay before each cmd and some bug fixes http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/commit/drivers/mmc/imx_esdhc.c?h=imx_v2009.08_12.01.01&id=a77c6fec8596891be96b2cdbc742c9824844b92a 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. This patch imports the polling part of both patches. The auto-clock gating code don't apply for i.MX6 as implemented in these two patches. SYSCTL_RSTA was defined twice. Remove one definition.

2012-05-08mmc: omap: handle controller errors properlyGrazvydas Ignotas
According to OMAP3 TRM, when the controller reports certain errors, driver must perform a software reset. This is done by setting a bit in SYSCTL and waiting it to clear: - SRC on command timeout (CTO) - SRD on data errors (DTO, DCRC and DEB) This fixes a problem seen on OMAP3 pandora board with some cards that won't work with a message printed multiple times: timedout waiting on cmd inhibit to clear Code loosely based on Linux omap_hsmmc driver.

2012-04-30Allow for parallel builds and saved outputAndy Fleming
The MAKEALL script cleverly runs make with the appropriate options to use all of the cores on the system, but your average U-Boot build can't make much use of more than a few cores. If you happen to have a many-core server, your builds will leave most of the system idle. In order to make full use of such a system, we need to build multiple targets in parallel, and this requires directing make output into multiple directories. We add a BUILD_NBUILDS variable, which allows users to specify how many builds to run in parallel. When BUILD_NBUILDS is set greater than 1, we redefine BUILD_DIR for each build to be ${BUILD_DIR}/${target}. Also, we make "./build" the default BUILD_DIR when BUILD_NBUILDS is greater than 1. MAKEALL now tracks which builds are still running, and when one finishes, it starts a new build. Once each build finishes, we run "make tidy" on its directory, to reduce the footprint. As a result, we are left with a build directory with all of the built targets still there for use, which means anyone who wanted to use MAKEALL as part of a test harness can now do so.

Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes displays which of these is actually built, but it's inconsistent. This is especially problematic since the "default" build for a given 85xx board can be either one, so if you don't see a message, you can't always know which size is being used. Not only that, but each board includes code that displays the message, so there is duplication. The 'bdinfo' command has been updated to display this information, so we don't need to display it at boot time. The board-specific code is deleted.

The image can be fetched from another processor's memory space by SRIO link connected between them. The processor boots from SRIO is slave, the processor boots from normal flash memory space and can help slave to boot from its memory space is master. They are different environments and requirements: master: 1. NOR flash for its own u-boot image, ucode and ENV space. 2. Slave's u-boot image in master NOR flash. 3. Normally boot from local NOR flash. 4. Configure SRIO switch system if needed. slave: 1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV. 2. Boot location should be set to SRIO1 or SRIO2 by RCW. 3. RCW should configure the SerDes, SRIO interfaces correctly. 4. Slave must be powered on after master's boot. 5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode locally. For the slave module, need to finish these processes: 1. Set the boot location to SRIO1 or SRIO2 by RCW. 2. Set a specific TLB entry for the boot process. 3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot. 4.
