| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to how the Makefile logic is we currently get DM_SPI support in SPL enabled by having DM_SPI enabled for full U-Boot but not having CONFIG_SPL_DM_SPI set. Add this missing option to boards that were inadvertently making use of it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add OP-TEE firmware node in stm32mp15 U-Boot DTSI. This node is needed since commit [1] that changed U-Boot/stm32mp15 to detect OP-TEE availability by probing the resource instead of relying on U-Boot configuration. The software sequence implemented by [1] is fine but U-Boot DTS/DTSI files were not updated accordingly since, hence OP-TEE presence is never detected by U-Boot, preventing Linux kernel from using OP-TEE resources. For consistency and to synchronize stm32mp15 DTSI files (excluding U-Boot specific DTSI files) with the Linux kernel ones, this change also moves the OP-TEE reserved memory nodes from board generic DTSI files to U-Boot specific board DTSI files.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fix in commit b7adcdd073c0 has the side-effect that the regulator will be disabled when requesting the relevant gpio in regulator_common_ofdata_to_platdata() and enabled in regulator_pre_probe() when the regulator was already enabled. This leads to a short interruption in the 3.3V power to the PCIe slot on the firefly-rk3399 which makes an ADATA SX8000NP NVMe SSD unhappy. Fix this by setting the GPIOD_IS_OUT_ACTIVE flag again when the 'regulator-boot-on' property is set, but check for this property explicitly instead of relying on the "boot_on" member of the uclass platdata.

The strtoul has well-defined semantics. It is defined by the C standard and POSIX. To quote the relevant section of the man pages, > If base is zero or 16, the string may then include a "0x" prefix, and the > number will be read in base 16; otherwise, a zero base is taken as 10 > (decimal) unless the next character is '0', in which case it is taken as > 8 (octal). Keeping these semantics is important for several reasons. First, it is very surprising for standard library functions to behave differently than usual. Every other implementation of strtoul has different semantics than the implementation in U-Boot at the moment. Second, it can result in very surprising results from small changes. For example, changing the string "1f" to "20" causes the parsed value to *decrease*. Forcing use of the "0x" prefix to specify hexidecimal numbers is a feature, not a bug. Lastly, this is slightly less performant, since the entire number is parsed twice. This fixes the str_simple_strtoul test failing with test/str_ut.c:29, run_strtoul(): expect_val == val: Expected 0x44b (1099), got 0x1099ab (1087915) test/str_ut.c:46, str_simple_strtoul(): 0 == run_strtoul(uts, str2, 0, 1099, 4): Expected 0x0 (0), got 0x1 (1) Signed-off-by: Sean Anderson <seanga2@gmail.com> CC: Michal Simek <michal.simek@xilinx.com> CC: Shiril Tichkule <shirilt@xilinx.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Those are two different variables with the same name. So the priv->vqmmc_dev was always NULL and thus voltage switch between modes never really suceeded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When eSDHC operates at 3.3v, damage can accumulate in an internal level shifter at a higher than expected rate. The faster the interface runs, the more damage accumulates. This issue now is found on LX2160A eSDHC1 for only SD card. The hardware workaround is recommended to use an on-board level shifter that is 1.8v on SoC side and 3.3v on SD card side. For boards without hardware workaround, this option could be enabled, ensuring 1.8v IO voltage and disabling eSDHC if no card. This option assumes no hotplug, and u-boot has to make all the way to to linux to use 1.8v UHS-I speed mode if has card. If you do not want the workaround for better user experience, of course you can choose to not select it running eSDHC in unsafe mode.
