2021-07-23reboot-mode: read the boot mode from GPIOs statusNandor Han3-0/+138
A use case for controlling the boot mode is when the user wants to control the device boot by pushing a button without needing to go in user-space. Add a new backed for reboot mode where GPIOs are used to control the reboot-mode. The driver is able to scan a predefined list of GPIOs and return the magic value. Having the modes associated with the magic value generated based on the GPIO values, allows the reboot mode uclass to select the proper mode.

2021-07-23reboot-mode: add support for reboot mode controlNandor Han5-0/+162
A new driver uclass is created to handle the reboot mode control. The new uclass driver is updating an environment variable with the configured reboot mode. The mode is extracted from a map provided at initialization time. The map contains a list of modes and associated ids.

This patch add support for using NXP's pca8574 I2C IO expander, which has only 8 IO lines. After this change the .data member's information from struct udevice_id are used to either sent one or two bytes. Moreover, the '_le16' suffix from pcf8575_i2c_{write|read}_le16() functions have been removed as now we also sent 8 bit data.

This change ensures both U-Boot and OP-TEE see the same content from shared memory when OP-TEE is invoked prior U-Boot relocation.

As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.

2021-07-18dm: pci: add option to map virtual system memory base addressDaniel Schwierzeck2-3/+19
On MIPS the DRAM start address respectively CONFIG_SYS_SDRAM_BASE is still used as a virtual, CPU-mapped address instead of being used as physical address. Converting all MIPS boards and generic MIPS code to fix that is not trivial. Due to the approaching deadline for PCI DM conversion, this workaround is required for MIPS boards with PCI support until the CONFIG_SYS_SDRAM_BASE issue could be solved. Add a compile-time option to let the PCI uclass core optionally map the DRAM address to a physical address when adding the PCI region of type PCI_REGION_SYS_MEMORY.

According to i.MX7ULP Reference Manual we should wait for WDOG unlock and reconfiguration to complete. Section "59.5.3 Configure Watchdog" provides the following example: DisableInterrupts; //disable global interrupt WDOG_CNT = 0xD928C520; //unlock watchdog while(WDOG_CS[ULK]==0); //wait until registers are unlocked WDOG_TOVAL = 256; //set timeout value WDOG_CS = WDOG_CS_EN(1) | WDOG_CS_CLK(1) | WDOG_CS_INT(1) | WDOG_CS_WIN(0) | WDOG_CS_UPDATE(1); while(WDOG_CS[RCS]==0); //wait until new configuration takes effect EnableInterrupts; //enable global interrupt Update U-Boot WDOG driver to align with i.MX7ULP reference manual.

According to i.MX7ULP Reference Manual the second word write for both UNLOCK and REFRESH operations must occur in maximum 16 bus clock. The current code is using writel() function which has a DMB barrier to order the memory access. The DMB between two words write may introduce some delay in certain circumstance, causing a WDOG timeout due to 16 bus clock window requirement. Replace writel() function by __raw_writel() to achieve a faster memory access and avoid such issue. Reviewed-by: Ye Li <ye.li@nxp.com> Signed-off-by: Breno Lima <breno.lima@nxp.com>
