* Merge branch 'for-2023.07' of ↵WIP/29Apr2023Tom Rini2023-04-299-81/+343
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://source.denx.de/u-boot/custodians/u-boot-mpc8xx This pull request adds support for the last CPU board from CS GROUP France (previously CSSI). That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence its name) and can be plugged in place of the CMPC885 board. In order to support that new board, the following changes are included in this series: - Make the mpc8xx watchdog driver more generic for reusing it with mpc83xx - Fix various small problems on mpc83xx platform - Add a GPIO Driver for QE GPIOs - Add support for mpc832x into mpc83xx SPI driver - Refactor existing board code that will be shared with new board - Add the new board
| * spi: mpc8xxx: Add support for SPI on mpc832xChristophe Leroy2023-04-061-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On mpc832x, SPI can be either handled by CPU or QE. In order to work in CPU mode, bit 17 of SPMODE has to be set to 1, that bit is called OP. Also, data is located at a different place than the one expected by the driver today. In 8 bits mode with REV set, data to be transmitted is located in the most significant byte while received data is located in second byte. So perform the necessary shifts. In order to differentiate with other CPUs, a new compatible is added for mpc832x: fsl,mpc832x-spi Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Cc: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

| | | | | | | | | | | | | | | | | | | | The mpc832x has GPIOs handled by the QUICC Engine. The registers are different from the one for the non QE mpc83xx GPIOs. Implement a GPIO driver for those. Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu>

| * watchdog: mpc8xxx: Make it genericChristophe Leroy2023-04-062-19/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same memory registers. Refactor the driver to get the register addresses from the device tree and use the compatible to know the prescale factor. Calculate the watchdog setup value from the provided timeout. Don't declare it anymore as an HW_WATCHDOG, u-boot will start servicing the watchdog early enough. On mpc8xx the watchdog configuration register is also used for configuring the bus monitor. So add it as an option to the watchdog when it is mpc8xx. When watchdog is not selected, leave the configuration of the initial SYPCR from Kconfig.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's quite a few instances of board-specific code doing off = fdt_path_offset(gd->fdt_blob, ...); ... ret = uclass_get_device_by_of_offset(..., off, &dev); looking for an eeprom or a pmic via some alias. Such code can be simplified a little if we have a helper for directly getting a device via device tree path (including being given as an alias).

The custom driver can be implemented like nvmxip_qspi in addition to the platform custom settings.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add block storage emulation for NVM XIP flash devices Some paltforms such as Corstone-1000 need to see NVM XIP raw flash as a block storage device with read only capability. Here NVM flash devices are devices with addressable memory (e.g: QSPI NOR flash). The implementation is generic and can be used by different platforms. Two drivers are provided as follows. nvmxip-blk : a generic block driver allowing to read from the XIP flash nvmxip Uclass driver : When a device is described in the DT and associated with UCLASS_NVMXIP, the Uclass creates a block device and binds it with the nvmxip-blk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present the code does ide_init() as a separate operation, then calls device_probe() to copy over the information. We can call ide_init() from probe just as easily. The only difference is that using 'ide init' twice will do nothing. However it already fails to copy over the new data in that case, so the effect is the same. For now, unbind the block devices and remove the IDE device, which causes the bus to be probed again. Later patches will fix this up fully, so that all blk_desc data is copied across. Since ide_reset() is only called from ide_init(), there is no need to init the ide_dev_desc[] array. This is already done at the end of ide_init() so drop this code. The call to uclass_first_device() is now within the probe() function of the same device, so does nothing. Drop it.
