All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
