1. Adding a new platform
|
|
0) Create a mach/${PLATFORM} directory, which must contain the platform-
|
|
specific I/O routines for user interface and filesystem access.
|
|
1) Specify platform storage types, setup platform specific access methods
|
|
and strategies, or fall back on the defaults
|
|
2) Create platform-specific c_putc, c_getc, c_memsz
|
|
3) Create a platform_init() method; this will be the first method to be
|
|
called from start_bootloader(). This must register platform-specific
|
|
4) Build up any re-usable peripheral methods required - for example, if
|
|
your platform requires a new filesystem class (that may be seen in
|
|
other platforms), please add support for it in filesys.
