* sf: Fix look for the fastest read commandJagannadha Sutradharudu Teki2014-12-13-56/+60
| | | | | | | | | | | Few of the spi controllers are only supports array slow read which is quite different behaviour compared to others. So this fix on sf will correctly handle the slow read supported controllers. Signed-off-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>

* x86: ich-spi: Fix a bug of reading from a non-64 bytes aligned addressBin Meng2014-12-13-15/+2
| | | | | | | | | | | | | The ich spi controller driver spi_xfer() tries to align reading address to 64 bytes when doing spi data in, which causes a bug of either infinite loop or a huge size memcpy(). Actually the ich spi controller does not have such requirement of 64 bytes alignment when reading data from spi slave devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts all Tegra boards over to use driver model for I2C. The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | usb_phy_enable should return status bit, but not phy mode bit, thus add a new function usb_phy_mode to query the PHY for it's mode and make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'. Include a new board weak function board_usb_phy_mode. If board code does not reimplement this function, it just call usb_phy_mode and return usb_phy_mode's return value. The reason to include such a weak function is: " SOC OTG core <--connect--> board HOST port, but no pin id for the board host port, so board can not use usb_phy_mode to return the phy mode, but define it's own rule."

Lets use it always, also for the main U-Boot. As all boards should have this HW connection. Testing on Siemens Draco (am335x) showed a small perfomance gain by using this ready pin to detect the NAND chip state. Here the values tested on Draco with Hynix 4GBit NAND: Without NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.947 seconds, 2947 ticks With NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.795 seconds, 2795 ticks So an increase of approx. 5%.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Boards using the TWL4030 regulator may not all use the LDOs the same way (e.g. MMC2 power can be controlled by another LDO than VMMC2). This delegates TWL4030 MMC power initializations to board-specific functions, that may still call twl4030_power_mmc_init for the default behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not every device has multiple MMC slots available, so it makes sense to enable only the required LDOs for the available slots. Generic code in omap_hsmmc will enable both VMMC1 and VMMC2, in doubt. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Reviewed-by: Tom Rini <trini@ti.com>
