[okl4-developer] Question about Build system (Platform related)

[Sean]

Dear all

Now I want to port the OKL4 to a new platform. But I had some questions
about the build system.

1. Does anyone give me some explanation of the relationship between
platform/s3c2410/tools/machine.py and the source codes in
platform/s3c2410/pistachio/src/

For example,  the content in machine.py
class s3c2410(arm920t):
    platform = "s3c2410"
    platform_dir = "s3c2410"
    memory = arm920t.memory.copy()
    timer_driver = "s3c2410_timer"
    rtc_driver = "s3c2410_rtc"
    serial_driver = "s3c2410_uart"
    lcd_driver = "s3c2410_lcd"
    touch_driver = "s3c2410_touch"
    spi_driver = "s3c2410_spi"
    drivers = [timer_driver, serial_driver, lcd_driver]
    memory_timer = [(0x51000000, 0x51001000)]
    interrupt_timer = [11, 12]
    memory_serial = [(0x50000000, 0x50001000)]
    interrupt_serial = [32, 33]
    memory_lcd = [(0x4d000000, 0x4d001000)]
    interrupt_lcd = [16]
    memory_rtc = [(0x57000000, 0x57001000)]
    interrupt_rtc = [30]
    v2_drivers = [("s3c2410_timer", "vtimer", memory_timer,
interrupt_timer),
                 ("s3c2410_uart", "vserial", memory_serial,
interrupt_serial),
                 ("s3c2410_lcd", "vlcd", memory_lcd, interrupt_lcd),
                 ("s3c2410_rtc", "vrtc", memory_rtc, interrupt_rtc)
                 # ("s3c2410_spi", "vbus"),
                 # ("s3c2410_touch", "vtouch"),
                 ]

and the function startup_system_mmu() in arch/arm/pistachio/src/init.cc
    if (!Platform::init(Platform::API_VERSION,
PlatformSupport::API_VERSION))
        for(;;);

How does the class "Platform" declare?


2. Where is the directories of the include files, and the relationship on
different paths
For example:
in platform/s3c2410/pistachio/src/head.spp
#include <kernel/l4.h>
#include <kernel/arch/asm.h>
#include <kernel/cpu/syscon.h>

I can't find the path like "include/kernel/" in the source tree.

Really need your helps, thanks very much!

Best Regards,
Sean
