* @author MCD Application Team
* @version V2.2.0
* @date 05-December-2014
* @brief CMSIS STM32F0xx Device Peripheral Access Layer Header File.
*
* The file is the unique include file that the application programmer
* is using in the C source code, usually in main.c. This file contains:
* - Configuration section that allows to select:
* - The STM32F0xx device used in the target application
* - To use or not the peripheral's drivers in application code(i.e.
* code will be based on direct access to peripheral's registers
* rather than drivers API), this option is controlled by
* "#define USE_HAL_DRIVER"

#
# Line description:
# <pattern> <parent> (<data> ...)
#
# <pattern>: is the pattern for the chip description to be searched for.
# The case of the pattern string is ignored.
# Pattern match symbols:
# ? - matches exactly one character
# * - matches none or more characters
# + - matches single or more characters
#
# <parent>: is the parent group name, where the search will continue.
# There are special parents names that controls traversing:
# "END" - Exit traversal.
# "+" - Don't change the parent. Use for split long line to two.
#
# <data>: space-separated list of preprocessor symbols supplied to the linker.
# -D option name is automatically prepended to each symbol definition
#
# All lines starting with # symbol are treated as Comments
#
# Recommended tree hierarchy:
#
# <device name> <family group> <device specific params>
# +- <family group> <family> <family group specific params>
# +- <family> <architecture> <device family specific params>
# +- <architecture> END <architecture specific params>
#
# You can split the long line into two or more by using "+" in the parent field,
# and defining same regex with appropriate parent on the next line. Example:
#
# device + PARAM1=aaa PARAM2=bbbb PARAM3=ccc PARAM4=dddd PARAM5=eeee
# device parent PARAM6=ffff PARAM7=gggg PARAM8=hhhh
# parent END
#
# The order of the lines is important. After the regex match, its parent will
# be used for match on the next line. If two regexp lines matches input, only
# the first will be evaluated, except special group definition "+"
#
# The regex matches entire sym
#
# Example:
#
# --- devices.data file ---
# stm32f05[01]?4* stm32f0 ROM=16K RAM=4K
# stm32f0 stm32 ROM_OFF=0x08000000 RAM_OFF=0x20000000
# stm32 END
#
# --- queried chip name ---
# stm32f051c8t6
#
# --- output of the awk script ---
# -DROM=16K -DRAM=4K -DROM_OFF=0x08000000 -DRAM_OFF=0x20000000
#
# The generated linker script file will contain sections rom and ram with
# appropriate initialization code, specified in linker file source linker.ld.S
