2019-10-25drivers: nand: brcmnand: fix nand_chip ecc layout structureWilliam Zhang
The current brcmnand driver is based on 4.18 linux kernel which uses mtd_set_ooblayout to set ecc layout. But nand base code in u-boot is from old kernel which does not use this new API and expect nand_chip.ecc.layout structure to be set. This cause nand_scan_tail function running into a bug check if the device has a different oob size than the default ones. This patch ports the brcmstb_choose_ecc_layout function from kernel 4.6.7 that supports the ecc layout struture and replaces the mtd_set_ooblayout method Signed-off-by: William Zhang <william.zhang@broadcom.com> Reviewed-by: Philippe Reynes <philippe.reynes@softathome.com>

2019-10-25mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTDFrieder Schrempf
Most boards currently use SPI_FLASH_MTD only in U-Boot proper, not in SPL. They often rely on hacks in the board header files to include this option conditionally. To be able to fix this, we previously introduced a separate option SPL_SPI_FLASH_MTD. Therefore we can now adjust the Makefile and change the code in sf_probe.c and sf_internal.h to use CONFIG_IS_ENABLED(SPI_FLASH_MTD). We also need to move all occurences of CONFIG_SPI_FLASH_MTD from the header files to the according defconfigs. The affected boards are socfpga, aristainetos, cm_fx6, display5, ventana, rcar-gen2, dh_imx6 and da850evm. We do this all in one patch to guarantee bisectibility. This change was tested with buildman to make sure it does not introduce any regressions by comparing the resulting binary sizes.

2019-10-24usb: dwc3: Kconfig: get rid of obsolete mode selectionJean-Jacques Hiblot
The mode selection for the DWC3 is kind of obsolete. The driver does not have to be host only or gadget only. This choice is confusing. All the remaining callers of dwc3_uboot_init() explicitly set dr_mode before calling the function, so none rely on a default behavior. Remove the choice menu and keep only the USB_DWC3_GADGET option. Enable it by default if USB_GADGET and USB_DWC3 are enabled. It must be disabled for the evb-rk3328 as it uses DWC2 for the gadget and DWC3 for the host.

2019-10-24usb: dwc3-generic: add a new host driver that uses the dwc3 coreJean-Jacques Hiblot
Currently the host driver used by dwc3-generic is "xhci-dwc3". This is a functional driver but it doesn't use the dwc3 core and, in particular, it lacks some bits that may be important. For example on the k2 platforms, it is important that the phy are properly suspended when the USB is not used anymore. The dwc3 core also has a partial support for quirks. The new driver can be used as a drop-in replacement for "xhci-dwc3". In terms of implementation, it may seem strange that 2 private structures dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this is simply that the xhci layer expects a struct xhci_ctrl at the beginning of the private data and it seemed wasteful to include it also for the peripheral case.
