2021-02-08arm: mvebu: Espressobin: Set default value for $fdtfile env variablePali Rohár
On Espressobin board value for $fdtfile cannot be determined at compile time and is calculated at board runtime code. This change uses a new option DEFAULT_ENV_IS_RW to allow modifying default_environment[] array at runtime and set into it correct value. This change also ensure that 'env default -a' set correct value to $fdtfile. Signed-off-by: Pali Rohár <pali@kernel.org> Acked-by: Andre Heider <a.heider@gmail.com>
2021-02-08env: Allow to set default_environment[] from board code via compile option ↵Pali Rohár
DEFAULT_ENV_IS_RW This change allows board code to modify default_environment[] array when compile option DEFAULT_ENV_IS_RW is specified in board config file. Some board default variables depend on runtime configuration which is not known at compile time. Therefore allow to set default_environment[] array as non-const and allow board code to modify it when it is needed.

- introduces some standard sysinfo options as a source, e.g. to read strapping pins to determine the board revision - allows the U-Boot version number to be included - allows the version number to be provided programmatically, e.g. to support the build system adding information after U-Boot is built
2021-02-06smbios: Allow a few values to come from sysinfoSimon Glass
While static configuration is useful it cannot cover every case. Sometimes board revisions are encoded in resistor straps and must be read at runtime. The easiest way to provide this information is via sysinfo, since the board can then provide a driver to read whatever is needed. Add some standard sysinfo options for this, and use them to obtain the required information. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2021-02-06x86: coral: Add sysinfo opsSimon Glass
These ops are missing at present which is not permitted. Add an empty operation struct. Note: If the uclass requires operations then the drivers should provide them. Otherwise, checking for missing operations must be done in every uclass operation, so it adds to code size. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2021-02-06sysinfo: Move #ifdef so that operations are always definedSimon Glass
At present the struct is not available unless SYSINFO is enabled. This is annoying since code it is not possible to use compile-time checks like CONFIG_IS_ENABLED(SYSINFO) with this header. Fix it by moving the #ifdef. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2021-02-06smbios: Add more options for the BIOS version stringSimon Glass
At present the version string is obtained from PLAIN_VERSION. Some boards may want to configure this using the device tree, since the build system can more easily insert things there after U-Boot itself is built. Add this option to the code. Also in some cases the version needs to be generated programmatically, such as when it is stored elsewhere in the ROM and must be read first. To handle this, keep a pointer around so that it can be updated later. This works by storing the last string in the context, since it is easier than passing out a little-used extra parameter. Provide a function to update the version string. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2021-02-06smbios: Drop the eos parameterSimon Glass
We can store this in the context and avoid passing it to each function. This makes it easier to follow and will also allow keeping track of the end of the string table (in future patches). Add an 'eos' field to the context and create a function to set it up. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2021-02-06smbios: Use a struct to keep track of contextSimon Glass
At present we pass the ofnode to each function. We also pass the 'eos' pointer for adding new strings. We don't track the current end of the string table, so have smbios_string_table_len() to find that. The code can be made more efficient if it keeps information in a context struct. This also makes it easier to add more features. As a first step, switch the ofnode parameter to be a context pointer. Update smbios_add_prop() at the same time to avoid changing the same lines of code in consecutive patches. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

According to the AM654x Data Manual[1], the setup timing in lower speed modes can only be met if the controller uses a falling edge data launch. To ensure this, the HIGH_SPEED_ENA (HOST_CONTROL[2]) bit should be cleared in default speed, SD high speed, MMC high speed, SDR12 and SDR25 speed modes.

With the new SW tuning App note[1], a custom tuning algorithm is required for eMMC HS200, HS400 and SD card UHS modes. The algorithm involves running through the 32 possible input tap delay values and sending the appropriate tuning command (CMD19/21) for each of them to get a fail or pass result for each of the values. Typically, the range will have a small contiguous failing window. Considering the tuning range as a circular buffer, the algorithm then sets a final tuned value directly opposite to the failing window.

DLL need only be enabled for speed modes and clock frequencies at or above 50 MHz. For speed modes that don't enable the DLL, we need to configure a static input delay value. This involves reading an optional itap-del-sel-* value from the device tree and configuring it for the appropriate speed mode. Therefore, move all dll configurations to their own functions and gate it with 50 MHz speed and a minimum mode. If both these conditions are not satisfied then configure delay chain modes.
