Other Parts Discussed in Thread: OMAP-L138

I grepped system_rev in the linux psp part of DVSDK 4.03 and I don't see anywhere where the davinci platform (I'm using OMAP-L138) actually sets that variable... can someone clue me in?  It's referenced (used) in the da850 evm setup file...

    system_rev variable sets at linux kernel as ATAG structure. (kernel/arch/arm/kernel/setup.c)

    ATAG structure comes from loader (U-Boot in case davinci board). (uboot/board/davinci/da8xxevm/da850evm.c)

    As I can see at source revision is configured by environment variable "maxcpuclk".
