This works on socfpga. The other user of this driver is Rockchip and the datasheet I found for the RK30xx indicated it supported highspeed modes as well. The Linux kernel has DT properties, e.g. "cap-mmc-highspeed", but none of the drivers in barebox support this at all. They all specify flags in their code.

There needs to be a way to supply the equivalent of the DT property bus-width this way to support devices that need to use a smaller bus. So that we don't need to put every flag that might get added to the MMC_CAP list into platform_data, just put the bus width ones into platform_data. The socfpga dts sources specify a bus-width of 4 so use that in the platform_data for socfpga.

Because of this, if the driver had set 8 or 4 bit width, it wasn't possible for the DT to specify that fewer pins were used on the board and a smaller width was necessary. Change this so the width in the DT overrides whatever widths the driver says it supports. There is no reason to have an incorrect device tree and it makes far more sense for the DT to override the driver default than for the driver default to override the DT. The widths the driver puts in host_caps before calling mci_of_parse() are considered the default if the DT doesn't specify bus-width. This should cause the least amount of change to existing boards, as despite a comment that no bus-width meant to use 1 bit, using the driver default is what was really happening. Unfortunately, half of existing drivers default to the largest width they support while the other half default to the smallest. Boards should just stick the width in the device tree.

MIPS architecture standard boot vector is 0xbfc00000 so on most MIPS SoCs all addresses higher than 0xbfc00000 belong to boot ROM or on-chip SRAM. Thus there's a simple criterion to check if PBL runs from ROM: just check if current PC is higher than 0xbfc00000. Some MIPS boards have ROM start address lower than 0xbfc00000 so it's reasonable to make ROM start address checking board-dependant. The pbl_blt macro checks if current pc is lower than the first argument (ROM start address). If so then next instruction executed is defined by the second argument of the macro.

| * | | | | | spi: i.MX: optimize transfers for ECSPI v2.3Sascha Hauer2015-11-302-2/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of writing one word to the txfifo and then wait until one is received in the rxfifo we can write while the txfifos are not full and read as long the rxfifos contain data. This makes transfers for the m25p80 driver around 7 times faster here. Unlike the last version this time we only optimize the common case with 8 bits per word and SPI_LSB_FIRST cleared. The other cases would require more bit shuffling of the data. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
