2020-10-30common: update: add a generic interface for FIT imageAKASHI Takahiro
The main purpose of this patch is to separate a generic interface for updating firmware using DFU drivers from "auto-update" via tftp. This function will also be used in implementing UEFI capsule update in a later commit. Signed-off-by: AKASHI Takahiro <[email protected]> Reviewed-by: Tom Rini <[email protected]>

2020-10-30dfu: rename dfu_tftp_write() to dfu_write_by_name()AKASHI Takahiro
This function is essentially independent from tftp, and will also be utilised in implementing UEFI capsule update in a later commit. So just give it a more generic name. In addition, a new configuration option, CONFIG_DFU_WRITE_ALT, was introduced so that the file will be compiled with different options, particularly one added in a later commit.

2020-10-30rtc: initialize emulated RTC from environment variableHeinrich Schuchardt
Up to now the emulated RTC is initialized using the U-Boot build time. With this patch the environment variable 'rtc_emul_epoch' can be used to provide a better initial time. The variable is a decimal string with the number of seconds since 1970-01-01. Here is an example where the RTC had not been probed yet: => setenv rtc_emul_epoch 1610109000 => date Date: 2021-01-08 (Friday) Time: 12:30:00 If the variable does not exist, the U-Boot build time is used as fallback. The environment variable may be set when shutting down the operating system if the U-Boot environment is exposed to the OS (cf. ENV_IS_IN_FAT and ENV_IS_IN_EXT4).

The SRAM on the PX30 is not big enough to hold multiple DDR configs so it needs to be selected during build. So far simply the DDR3 config was always selected and getting DDR4 or LPDDR2/3 initialized would require a code modification.

2020-10-29dm: Use driver_info index instead of pointerSimon Glass
At present we use a 'node' pointer in the of-platadata phandle_n_arg structs. This is a pointer to the struct driver_info for a particular device, and we can use it to obtain the struct udevice pointer itself. Since we don't know the struct udevice pointer until it is allocated in memory, we have to fix up the phandle_n_arg.node at runtime. This is annoying since it requires that SPL's data is writable and adds a small amount of extra (generated) code in the dm_populate_phandle_data() function. Now that we can find a driver_info by its index, it is easier to put the index in the phandle_n_arg structures. Update dtoc to do this, add a new device_get_by_driver_info_idx() to look up a device by drive_info index and update the tests to match. Signed-off-by: Simon Glass <[email protected]>

2020-10-29dm: Add a test for of-platdata parent informationSimon Glass

2020-10-29dm: Support parent devices with of-platdataSimon Glass
At present of-platdata does not provide parent information. But this is useful for I2C devices, for example, since it allows them to determine which bus they are on. Add support for setting the parent correctly, by storing the parent driver_info index in dtoc and reading this in lists_bind_drivers(). This needs multiple passes since we must process children after their parents already have been bound. Signed-off-by: Simon Glass <[email protected]>

2020-10-29dm: Use an allocated array for run-time device infoSimon Glass
At present we update the driver_info struct with a pointer to the device that it created (i.e. caused to be bound). This works fine when U-Boot SPL is stored in read-write memory. But on some platforms, such as Intel Apollo Lake, it is not possible to update the data memory. In any case, it is bad form to put this information in a structure that is in the data region, since it expands the size of the binary. Create a new driver_rt structure which holds runtime information about drivers. Update the code to store the device pointer in this instead. Also update the test check that this works.

2020-10-29dm: test: Add a check that all devices have a dev valueSimon Glass
With of-platdata, the driver_info struct is updated with the device pointer when it is bound. This makes it easy for a device to be found by its driver info with the device_get_by_driver_info() function. Add a test that all devices (except the root device) have such an entry. Fix a bug that the function does not set *devp to NULL on failure, which the documentation asserts. Signed-off-by: Simon Glass <[email protected]>

This reverts commit 942b5fc03218d1c94468fc658e7dec65dabcc830. This is partial revert of the above commit. mmc_of_parse() is reading no-1-8-v from device tree and if set, it is clearing the UHS speed capabilities of cfg->host_caps. cfg->host_caps &= ~(UHS_CAPS | MMC_MODE_HS200 | MMC_MODE_HS400 | MMC_MODE_HS400_ES); This is still missing to clear UHS speeds like SDHCI_SUPPORT_SDR104, SDHCI_SUPPORT_SDR50 and SDHCI_SUPPORT_DDR50. Even if we clear the flags SDHCI_SUPPORT_XXX in mmc_of_parse(), these speed flags are getting set again in cfg->host_caps in sdhci_setup_cfg(). The reason for this is, SDHCI_SUPPORT_XXX flags are cleared only if controller is not capable of supporting MMC_VDD_165_195 volts. if (caps & SDHCI_CAN_VDD_180) cfg->voltages |= MMC_VDD_165_195; if (!(cfg->voltages & MMC_VDD_165_195)) caps_1 &= ~(SDHCI_SUPPORT_SDR104 | SDHCI_SUPPORT_SDR50 | SDHCI_SUPPORT_DDR50); It means "no-1-8-v", which is read from DT is not coming in to effect. So it is better we keep the host quirks(SDHCI_QUIRK_NO_1_8_V) to clear UHS speeds based on no-1-8-v from device tree. Hence revert the functionality related to no-1-8-v only, rest is fine in the patch.
