| | | | | | | | | | | | | | | Several options are presenting themselves on a various boards where the options are clearly not used. (ie, SPL/TPL options when SPL or TPL are not defined) This patch is not attempting to be a complete list of items, but more like low hanging fruit. In some instances, I wasn't sure of DM was required, so I simply made them SPL or TPL.

| | | | | | | | | | | | | | | | | | | | | | This patch fixes not enabled uart2 (and hence serial console) on i.MX53 devices. After following commit 1d255904c306 ("ARM: dts: imx: imx53: Synchronize iMX53 DT with Linux") from the uart2 compatible the 'fsl,imx7d-uart' has been removed (which was correct). However, the root cause of the problem was the commit 98d62e618bb9 ("arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC") which introduced this compatible. Moreover, without this patch all i.MX53 UARTs are not usable as neither 'fsl,imx53-uart' nor 'fsl,imx21-uart' are in compatible IDs in drivers/serial/serial_mxc.c file. The fix is to add 'fsl,imx53-uart' and 'fsl,imx21-uart' as compatibles for the aforementioned serial driver (those are also defined in the Linux kernel).

* IMX: serial: dm: Set DM_FLAG_PRE_RELOC in the IMX uart driverLukasz Majewski2019-07-191-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | The DM_FLAG_PRE_RELOC shall be set unconditionally as this driver is going to be re-used in both early SPL and U-Boot proper's pre-reloc. For i.MX based devices it is crucial to have available the serial console before relocation (otherwise the board may hand). The device definition may be provided either via device tree description or with U_BOOT_DEVICE(mxc_serial) definition. In the latter case the device will not bind in U-Boot proper when DM_FLAG_PRE_RELOC is not set. The !CONFIG_IS_ENABLED(OF_CONTROL) #if check was set as a "workaround" for DM problem described in following commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers"). Let's look on this check more thoroughly - we add this flag if the board doesn't support OF_CONTROL. This is a bit strange as the serial_mxc.c can be used with CONFIG_DM_SERIAL but without corresponding device tree description (OF_CONTROL). In such case the aforementioned U_BOOT_DEVICE(mxc_serial) definition is used. Other boards/SoCs have this flag set unconditionally for serial driver. Signed-off-by: Lukasz Majewski <lukma@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For STM32MP, the watchdog is based on DM and the function watchod_reset call the function uclass_get_device(UCLASS_WDT) to found the driver associated IWDG2. As this reset is not mandatory in debug putc (the uart fifo will be empty after some us), we can simplify the code by removing this call. And this patch avoid issue when putc is called before initialization of DM core, before the parsing of the device tree parsing and each node bound to driver; that also avoid memory leak.

As this can happen via a printf sneaking in before the port calls debug_uart_init(), introduce a config option to ignore characters before the debug uart is initialized. This is done by reading the baudrate divisor and aborting if is zero. The Kconfig option is required as reading the baudrate divisor does not seem to work for all ns16500 compatibles (which is why the last attempt on this has been reverted in 1a67969a99). Tested on socfpga_cyclone5_socrates. Signed-off-by: Simon Goldschmidt <simon.k.r.goldschmidt@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
