* drivers: mux: mmio-based syscon mux controllerJean-Jacques Hiblot2020-10-283-0/+157
| | | | | | | | | | This adds a driver for mmio-based syscon multiplexers controlled by bitfields in a syscon register range. This is heavily based on the linux mmio-mux driver.

| * efi_loader: Disable devices before handing over controlIlias Apalodimas2020-10-271-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot Driver Model is supposed to remove devices with either DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting. Our bootm command does that by explicitly calling calling "dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any USB devices. The EFI equivalent is doing none of those at the moment. As a result probing an fTPM driver now renders it unusable in Linux. During our (*probe) callback we open a session with OP-TEE, which is supposed to close with our (*remove) callback. Since the (*remove) is never called, once we boot into Linux and try to probe the device again we are getting a busy error response. Moreover all uclass (*preremove) functions won't run. So let's fix this by mimicking what bootm does and disconnect devices when efi_exit_boot_services() is called.

| | | | | | | | | | | | | | | | | | | | An UEFI application may change the value of the register that gd lives in. But some of our functions like get_ticks() access this register. So we have to set the gd register to the U-Boot value when entering a trace point and set it back to the application value when exiting the trace point.

| | | | | | | | | | | | | | | | | | | | | | On a board without hardware clock this software real time clock can be used. The build time is used to initialize the RTC. So you will have to adjust the time either manually using the 'date' command or use the 'sntp' to update the RTC with the time from a network time server. See CONFIG_CMD_SNTP and CONFIG_BOOTP_NTPSERVER. The RTC time is advanced according to CPU ticks. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some drivers use macro pr_cont() for continuing a message sent via printk. Hence if we want to convert printk messaging to using the logging system, we must support continuation of log messages too. As pr_cont() does not provide a message level we need a means of remembering the last log level. With the patch a pseudo log level LOGL_CONT as well as a pseudo log category LOGC_CONT are introduced. Using these results in the application of the same log level and category as in the previous log message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is unsafe to enable OF_BOARD_FIXUP only based on OF_SEPARATE. OF_SEPARATE may indicate that the user wishes U-Boot to use a different device tree than one obtained via OF_PRIOR_STAGE. However, OF_SEPARATE may also indicate that the device tree which would be obtained via OF_PRIOR_STAGE is invalid, nonexistant, or otherwise unusable. In this latter case, enabling OF_BOARD_FIXUP will result in corruption of the device tree. To remedy this, only enable OF_BOARD_FIXUP if U-Boot is configured for S-Mode.

If ramdisk size is 0x800000 and start address is 0x2700000, then it's used until 0x02efffff, not 0x02f00000. But it's detected to overlapt RD image, when kernel start address is 0x02f00000. Because it's doing wrong calculation about rd_len. This patch fixed wrong calculation address position when check condition.
