# Add a new board
|
||||||
|
|
||||||
|
Before adding a new board, you may consider if your board can use another
|
||||||
|
board definition and simply overwrite the weak symbols.
|
||||||
|
|
||||||
|
If you think it is worth adding a new board, you need to perform the following
|
||||||
|
steps:
|
||||||
|
|
||||||
|
* Decide for a meaningful board name (refered to as <board> below). It should
|
||||||
|
be specific enough (not openrisc..), but be rather generic if it may cover
|
||||||
|
similar boards as well.
|
||||||
|
|
||||||
|
* Create a file <board>.S (assembler) or <board>.c (C). Of course, C is easier
|
||||||
|
to write and you can implement everything in C, but there are restrictions:
|
||||||
|
|
||||||
|
* There is an early initialization function. It is called before the C
|
||||||
|
library and even the stack are initialized. A default implementation skips
|
||||||
|
this step, so everything will compile, but if you really need
|
||||||
|
initialization that early you are bound to assembly language.
|
||||||
|
|
||||||
|
* You essentially should not use the C library functions as this may lead to
|
||||||
|
link issues and circular dependencies.
|
||||||
|
|
||||||
|
You can copy board_tmpl.S or board_tmpl.c as starting point for your board.
|
||||||
|
|
||||||
|
* The following symbols must be defined in your board file:
|
||||||
|
|
||||||
|
* _or1k_board_mem_base: Memory base address
|
||||||
|
|
||||||
|
* _or1k_board_mem_size: Memory size
|
||||||
|
|
||||||
|
* _or1k_board_clk_freq: Clock frequency
|
||||||
|
|
||||||
|
* _or1k_board_uart_base: UART base address. Set to 0 if no UART present.
|
||||||
|
|
||||||
|
* _or1k_board_uart_baud: UART baud rate. Only used if UART base is > 0
|
||||||
|
|
||||||
|
* _or1k_board_uart_IRQ: UART interrupt line. Only used if UART base is > 0
|
||||||
|
|
||||||
|
You can define a weak attribute for all of the symbols so that they can
|
||||||
|
be overwritten by the user (more flexibility).
|
||||||
|
|
||||||
|
* The following functions need to be implemented:
|
||||||
|
|
||||||
|
* _or1k_board_init: Is called after C library initialization and UART
|
||||||
|
initialization.
|
||||||
|
|
||||||
|
* _or1k_board_exit: Is called after the program has exited and the C library
|
||||||
|
finished all deconstructions etc.
|
||||||
|
|
||||||
|
Similar to the symbols you can define those functions weak.
|
||||||
|
|
||||||
|
* The following functions can be implemented:
|
||||||
|
|
||||||
|
* _or1k_board_init_early: Only in assembly (see above). Is called before
|
||||||
|
anything is initialized, not even the stack! You can use all registers
|
||||||
|
in this function. The default implementation in crt0.S skips this step,
|
||||||
|
which is fine in most cases. If you decide to implement it, you need to
|
||||||
|
define it with the global attribute to overwrite the default
|
||||||
|
implementation. It is recommended to do so in assembler board files to
|
||||||
|
keep the ability to overwrite the default implementation by the user.
|
||||||
|
|
||||||
|
When you are done with your board, add it to libgloss/or1k/Makefile.in to the
|
||||||
|
BOARDS variable and compile.
