2020-10-28test: mux-cmd: Add tests for the 'mux' commandWIP/2020-10-28-mux-driver-frameworkPratyush Yadav3-0/+179
Tests tests run the three mux subcommands: list, select, and deselect, and verify that the commands do what we expect. Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2020-10-28cmd: Add a mux commandPratyush Yadav3-0/+191
This command lets the user list, select, and deselect mux controllers introduced with the mux framework on the fly. It has 3 subcommands: list, select, and deselect. List: Lists all the mux present on the system. The muxes are listed for each chip. The chip is identified by its device name. Each chip can have a number of mux controllers. Each is listed in sequence and is assigned a sequential ID based on its position in the mux chip. It lists details like ID, whether the mux is currently selected or not, the current state, the idle state, and the number of states. A sample output would look something like: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no unknown as-is 0x4 1 no 0x2 0x2 0x10 2 no 0x73 0x73 0x100 another-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x2 0x2 0x4 Select: Selects a given mux and puts it in the specified state. This subcommand takes 3 arguments: mux chip, mux ID, state to set the mux in. The arguments mux chip and mux ID are used to identify which mux needs to be selected, and then it is selected to the given state. The mux needs to be deselected before it can be selected again in another state. The state should be a hexadecimal number. For example: => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 => mux select a-mux-controller 0 0x3 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 yes 0x3 0x1 0x4 1 no 0x1 0x1 0x4 Deselect: Deselects a given mux and puts it in its idle state. This subcommand takes 2 arguments: the mux chip and mux ID to identify which mux needs to be deselected. So in the above example, we can deselect mux 0 using: => mux deselect a-mux-controller 0 => mux list a-mux-controller: ID Selected Current State Idle State Num States 0 no 0x1 0x1 0x4 1 no 0x1 0x1 0x4 Signed-off-by: Pratyush Yadav <p.yadav@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Provide tests to check the behavior of the multiplexer framework. Two sets of tests are added. One is using an emulated multiplexer driver that can be used to test basic functionality like select, deselect, etc. The other is using the mmio mux which adds tests specific to it.

2020-10-27efi_loader: Disable devices before handing over controlIlias Apalodimas1-0/+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.

2020-10-27rtc: provide an emulated RTCHeinrich Schuchardt4-0/+93
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>

2020-10-27log: allow for message continuationHeinrich Schuchardt4-5/+38
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.

2020-10-26riscv: Only enable OF_BOARD_FIXUP for S-ModeSean Anderson1-1/+1
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.
