2019-05-23serial: stm32: remove watchog reset in debug putcPatrick Delaunay
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.

2019-04-09serial: atmel_usart: Use fixed clock value in SPL version with DM_SERIALStefan Roese
This patch adds an alterative SPL version of atmel_serial_enable_clk(). This enables the usage of this driver without full clock support (in drivers and DT nodes). This saves some space in the SPL image. Please note that this fixed clock support is only added to the SPL code in the DM_SERIAL part of this file. All boards not using SPL & DM_SERIAL should not be affected. This patch also introduces CONFIG_SPL_UART_CLOCK for the fixed UART input clock. It defaults to 132096000 for ARCH_AT91 but can be set to a different value if needed.

2019-01-15serial: ns16550: fix debug uart putc called before initSimon Goldschmidt
If _debug_uart_putc() is called before _debug_uart_init(), the ns16550 debug uart driver hangs in a tight loop waiting for the tx FIFO to get empty. 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).

2018-12-12spl: fix build failure with !CONFIG_SPL_PCI_SUPPORTSekhar Nori
Building U-Boot with CONFIG_PCI and CONFIG_DM_PCI enabled, but CONFIG_SPL_PCI_SUPPORT disabled, results in following linker error: lib/built-in.o: In function `fdtdec_get_pci_bar32': lib/fdtdec.c:305: undefined reference to `dm_pci_read_bar32' fdtdec.c:305:(.text.fdtdec_get_pci_bar32+0x24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `dm_pci_read_bar32' This is because reference to dm_pci_read_bar32() remains in lib/fdtdec.c while SPL build does not descend into drivers/pci directory in drivers/Makefile if CONFIG_SPL_PCI_SUPPORT is not enabled. Fix this by applying appropriate #define guards in lib/fdtdec.c. It looks like ns16550.c has the same problem, so fixed that too. To simplify this, CONFIG_SPL_PCI_SUPPORT is renamed to CONFIG_SPL_PCI (enables use of CONFIG_IS_ENABLED() macro).

2018-11-14serial: Remove DM_FLAG_PRE_RELOC flag in various driversBin Meng
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be bound before relocation. However due to a bug in the DM core, the flag only takes effect when devices are statically declared via U_BOOT_DEVICE(). This bug has been fixed recently by commit "dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()", but with the fix, it has a side effect that all existing drivers that declared DM_FLAG_PRE_RELOC flag will be bound before relocation now. This may expose potential boot failure on some boards due to insufficient memory during the pre-relocation stage. To mitigate this potential impact, the following changes are implemented: - Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver only supports configuration from device tree (OF_CONTROL) - Keep DM_FLAG_PRE_RELOC flag in the driver only if the device is statically declared via U_BOOT_DEVICE() - Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
