Nathaniel Graff 8b40260283 boards/riscv32: Add support for the HiFive1 Rev B
The HiFive1 Rev B adds the following features to the
original HiFive1:

 - A second UART peripheral 'uart_1'
 - A hardware I2C peripheral 'i2c_0'
 - Segger J-Link OB
 - An ESP32-WROOM attached to the 'spi_1' peripheral bus

Filip Kokosinski e0a825003d riscv32: use device tree defines in linker
Delete memory-related configs from defconfig and use device tree based
macros in general riscv32 linker script instead of Kconfig ones.

Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

hardcoded in soc.h

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
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

Andrzej Głąbek f39ba7230d dts_fixups: Update labels generated from DTS with DT_ prefix
All labels containing "_<8-hex-digits>_" or "16550_<3or6-hex-digits>_"
in their names, assumed to be generated by the extracting script,
are updated with the DT_ prefix, to reflect the recent changes made
to the script.

Sebastian Bøe 8eb734cd82 DT: Rename from dts.fixup to dts_fixup.h
The Zephyr configuration system uses many different files in many
different formats. It makes it a lot easier for users to understand
what these files do if when we use the correct file extensions.

To this end we rename the dts.fixup files to the correct file
extension '.h'.

This is a breaking change for out-of-tree fixup files. Such files will
be detected and given an appropriate error message.

Kumar Gala 11e98fa925 riscv32: sifive-freedom: Move dts.fixup into soc dir
The dts.fixup for the hifive1 board was not board specific but related
to the SoC.  Move the dts.fixup into the SoC dir so any other boards
using this same SoC will take advantage of it.

Anas Nashif 279cc2e448 riscv32: move soc to top-level dir soc/
Move the SoC outside of the architecture tree and put them at the same
level as boards and architectures allowing both SoCs and boards to be
maintained outside the tree.
