20202902f2
These changes were obtained by running a script created by Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following specification: 1. Read the contents of all dts_fixup.h files in Zephyr 2. Check the left-hand side of the #define macros (i.e. the X in #define X Y) 3. Check if that name is also the name of a Kconfig option 3.a If it is, then do nothing 3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it has neither of these two prefixes 4. Replace the use of the changed #define in the code itself (.c, .h, .ld) Additionally, some tweaks had to be added to this script to catch some of the macros used in the code in a parameterized form, e.g.: - CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS - CONFIG_UART_##idx##_TX_PIN - I2C_SBCON_##_num##_BASE_ADDR and to prevent adding DT_ prefix to the following symbols: - FLASH_START - FLASH_SIZE - SRAM_START - SRAM_SIZE - _ROM_ADDR - _ROM_SIZE - _RAM_ADDR - _RAM_SIZE which are surprisingly also defined in some dts_fixup.h files. Finally, some manual corrections had to be done as well: - name##_IRQ -> DT_##name##_IRQ in uart_stm32.c Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>
