Move the gdsys Controlcenter DC specific build time kwbimage.cfg generation code into the mach-mvebu/ directory to be shared by all 32bit mvebu platforms. Remove board specific kwbimage.cfg files, and use the generated one instead. These files are all identical, with two exceptions. Clearfog and Helios4 use the sdio boot device, whereas all others use spi. Update the defconfigs for the exceptional boards to generate the same kwbimage.cfg as before. Signed-off-by:

The Assigned Clock parents and rates misses the fact that a "0" entry can be passed to skip setting a parent or rate of an assigned clock as described in the Linux clock bindings at [1]. This patch simply skips the clock reparenting if the DT parsing returns -ENOENT and the clock rate setting if "0" is passed as clock rate.

Even though the exception vector table is a fundamental part of the ARM architecture, U-Boot mostly does not make real use of it, except when crash dumping. But having it in takes up quite some space, partly due to the architectural alignment requirement of 2KB. Since we don't take special care of that, the compiler adds a more or less random amount of padding space, which increases the image size quite a bit, especially for the SPL. On a typical Allwinner build this is around 1.5KB of padding, plus 1KB for the vector table (mostly padding space again), then some extra code to do the actual handling. This amounts to almost 10% of the maximum image size, which is quite a lot for a pure debugging feature. Add a Kconfig symbol to allow the exception vector table to be left out of the build for the SPL. For now this is "default y" for everyone, but specific defconfigs, platforms or .config files can opt out here at will, to mitigate the code size pressure we see for some SPLs.

The arm64 exception handling code is quite big, mostly due to architectural alignment requirements. Each exception entry spans 32 instructions, which sounds generous, but is too small to fit all of the save/branch/restore code in there. So at the moment we use only four instructions, branching into shared save and restore routines. To not leave the space for those remaining 28 instructions wasted, let's split the save and restore routines and stuff them into the gaps. This saves about 250 bytes of code, which is helpful for those tight SPLs. Signed-off-by: -
Several boards do not use the default UART3, so they do a check for ifdef CONFIG_SPL_BUILD and enable the pointer for CONFIG_SYS_NS16550_COMx to point to OMAP34XX_UARTx. Let's consoldate this all into one place, and remove them from the individual boards. Signed-off-by:Adam Ford <aford173@gmail.com>

This patch adds support for STMicroelectronics STM32 ADC (analog to digital converter). It's originally based on Linux kernel v4.18-rcs drivers/iio/adc/stm32-adc*. It's composed of: - core driver (UCLASS_SIMPLE_BUS) manages common resources (clk, regu). - child drivers (UCLASS_ADC) declare each ADC, channels and handle conversions. This driver currently supports STM32H7 and STM32MP1 ADC. Signed-off-by:

device_get_supply_regulator() only needs to be called once. But each time there's call to adc_vxx_value() for instance, it calls adc_vxx_platdata_update() -> device_get_supply_regulator(). So, move device_get_supply_regulator() to pre_probe() routine. This also allows vdd_supply/vss_supply to be provided directly from uc_pdata, e.g dt-binding variant like stm32-adc provide its own 'vref-supply'. Signed-off-by:
