2018-02-19mmc: omap_hsmmc: add signal voltage selection supportJean-Jacques Hiblot
I/O data lines of UHS SD card operates at 1.8V when in UHS speed mode (same is true for eMMC in DDR and HS200 modes). Add support to switch signal voltage to 1.8V in order to support UHS cards and eMMC HS200 and DDR modes.

2018-02-19mmc: omap_hsmmc: Add support to get pinctrl values and max frequency for ↵Kishon Vijay Abraham I
different hw revisions AM572x SR1.1 requires different IODelay values to be used than that used in AM572x SR2.0. These values are populated in device tree. Add capability in omap_hsmmc driver to extract IOdelay values for different silicon revision. The maximum frequency is also reduced when using a ES1.1. To keep the ability to boot both revsions with the same dtb, those values can be provided by the platform code.

2018-02-19ARM: OMAP5/DRA7: Enable iodelay recalibration to be done from ubootKishon Vijay Abraham I
Add a new API to perform iodelay recalibration without isolate io to be used in uboot. The data manual of J6/J6 Eco recommends to set different IODELAY values depending on the mode in which the MMC/SD is enumerated in order to ensure IO timings are met. The MMC driver can use the new API to set the IO delay values depending on the MMC mode. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2018-02-19mmc: omap_hsmmc: Workaround for errata id i802Jean-Jacques Hiblot
According to errata i802, DCRC error interrupts (MMCHS_STAT[21] DCRC=0x1) can occur during the tuning procedure. The DCRC interrupt, occurs when the last tuning block fails (the last ratio tested). The delay from CRC check until the interrupt is asserted is bigger than the delay until assertion of the tuning end flag. Assertion of tuning end flag is what masks the interrupts. Because of this race, an erroneous DCRC interrupt occurs. The suggested workaround is to disable DCRC interrupts during the tuning procedure which is implemented here.

2018-02-19mmc: omap_hsmmc: add support to set default io voltageKishon Vijay Abraham I
"ti,dual-volt" is used in linux kernel to set the voltage capabilities. For host controller dt nodes that doesn't have "ti,dual-volt", it's assumed 1.8v is the io voltage. This is not always true (like in the case of beagle-x15 where the io lines are connected to 3.3v). Hence if "no-1-8-v" property is set, io voltage will be set to 3v.

2018-02-19mmc: omap_hsmmc: cleanup clock configurationJean-Jacques Hiblot

Starting the clock and stopping the clock can be used irrespective of setting the clock (For example during iodelay recalibration). Also set the clock only if there is a change in frequency.

2018-02-16ARM: rmobile: Convert Porter to SPLMarek Vasut
Due to size limitations of the MERAM, switch U-Boot to SPL. The SPL is loaded by the SPI_LOADER into MERAM and then loads U-Boot proper into DRAM. This way U-Boot can freely grow in size in DRAM, as there is plenty of it.

2018-02-15arm: socfpga: use imply instead of select where applicableSimon Goldschmidt
Kconfig should only 'select' features that are required for an arch. Standard features that can be disabled without breaking board support should use 'imply' instead, to allow users to disable it. These options are changed for mach-socfpga: - DM_SPI & DM_SPI_FLASH: only required with QSPI support enabled - SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION: the boot rom supports a partitionless mode also, where SPL is located at address 0 - HW_WATCHDOG: while all mainline board defconfigs use it, U-Boot should still work without it.

This patch adds "spi-flash" to the compatible list of the qspi flash chip for all socfpga boards. This is required to make qspi work on these boards on top of the recent fixes. Without the "spi-flash" compatible string for the flash chip, the speed cannot be read and a speed of 0Hz is used (which results in a divide-by-zero on these boards).

The current version of binutils does not swallow the error. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=888403 The necessary constant IMAGE_SUBSYSTEM_EFI_APPLICATION is already defined in pe.h. So let's factor out asm-generic/pe.h for the image subsystem constants and use it in our assembler code. IMAGE_SUBSYSTEM_SAL_RUNTIME_DRIVER does not exist in the specification let's use IMAGE_SUBSYSTEM_EFI_ROM instead.

2018-02-04imx: mx7: run sec_init for CAAM RNGBryan O'Donoghue
This patch adds a sec_init call into arch_misc_init(). Doing so in conjunction with the patch "drivers/crypto/fsl: assign job-rings to non-TrustZone" enables use of the CAAM in Linux when OPTEE/TrustZone is active. u-boot will initialise the RNG and assign ownership of the job-ring registers to a non-TrustZone context. With recent changes by Lukas Auer to fully initialize the RNG in sec_init() this means that u-boot will hand-off the CAAM in a state that Linux then can use the CAAM without touching the reserved DECO registers. This change is safe both for the OPTEE/TrustZone boot path and the regular non-OPTEE/TrustZone boot path.

It is used when the nature direction of a pin depending on selected alternative function is an output, but it is needed to read the real logic value on a pin. The SION bit can be used in: • Loopback: the module of a selected alternative function drives the pad and also receives the pad value as an input • GPIO capture: the module of a selected alternative function drives the pin and the value is captured by the GPIO SION bit is not necessary when the pin is configured as a peripheral apart specific silicon bug.
