* ARM: i.MX8M: Add DDR controller supportSascha Hauer2020-02-192-0/+504
| | | | | | | | | | | | | | | This adds the DDR driver for the i.MX8MQ/i.MX8MM. It's taken from U-Boot v2020.04-rc1 with slight modifications for barebox The i.MX8MQ boards in the tree currently use the output of an earlier version of the NXP i.MX8M DDR Tool which doesn't use a controller driver but instead does most stuff in board code. It seems this can coexist with the new driver, only a few helper functions that previously lived in arch/arm/mach-imx/imx8-ddrc.c are now provided by the new driver. Tested on an i.MX8MM EVK Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | The Rohm bd71837 is a PMIC used on the NXP i.MX8MM EVK eval board. For now only add the register definitions to be used by the lowlevel code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clk: imx: Add pll14xx supportSascha Hauer2020-02-191-0/+7
| | | | | | | | This adds support for the pll14xx found on i.MX8MM devices. This is taken from the Kernel as of v5.5. Since we'll need some early setup for the PLL a PBL hook is added to be called from lowlevel code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* usb: gadget: fsl_udc: Add PBL image loading supportSascha Hauer2020-02-191-0/+6
| | | | | | | | | | | | | | | | | For boards that do the RAM setup in code we can up to now only download the PBL part to SRAM. This patch adds support for downloading the rest of the image after the RAM has been configured. The ROM is nice enough to leave the USB controller initialized after a download, so we don't have to reinitialize it, but can simply continue to use the controller. Like all two-staged loading processes on i.MX this needs board support, it will only work when a board calls imx_barebox_load_usb() or one of the SoC specific variants. This needs the host counterpart in imx-usb-loader which is done in the next patch. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts 03b59bdb64 ("paramter: The dev_add_param_*() return ERR_PTR(), change no-ops to return ERR_PTR(-ENOSYS) instead of NULL"). Most callers of dev_add_param_*() don't care about whether CONFIG_PARAMETER is enabled or not. The remaining ones have already been prepared for getting a NULL pointer.

OP-TEE will then be started and barebox will continue to run in normal mode. The function start_optee_early should be used in a boards lowlevel.c file. Ensure that barebox has been relocated and a proper c environment has been setup beforehand. Depending on the OP-TEE configuration, the fdt will be modified. If the internal barebox device tree is passed, OP-TEE will overwrite barebox PBL memory during this modification. Copy the fdt to a save memory location beforehand to avoid a corruption of barebox PBL memory. This also moves the OP-TEE Kconfig symbols into a separate menu.
